Event-driven email alternatives
Customer.io Alternatives for Email Automation in 2026
The best Customer.io alternative depends on why you are leaving. If it is the bill, Loops reads $99 a month at 9,998 subscribers against $145 for 10k profiles on Customer.io Essentials. If your customers are companies, move to Userlist. If marketers rather than engineers now run the journeys, pick ActiveCampaign, and if you are a coach or course seller who mostly sends launches and welcome sequences, Kit (formerly ConvertKit) is simpler and cheaper.
Why people leave Customer.io
Customer.io is built for teams that send product events and want messages to react to them. Essentials is $100 a month for 5k profiles, billed monthly, with $145 at 10k, $235 at 20k, $325 at 30k, $415 at 40k and $505+ at 50k and above; each extra profile costs $0.009, which is where the extra $90 per 10,000 profiles comes from. Premium starts at $1,000 a month, billed yearly, with custom profile volume, and Customer.io lists managed deliverability as not included on Essentials. Three things push teams to look elsewhere: the profile count grows faster than the revenue, someone has to keep sending clean events, and the people who write the emails want a simpler editor.
The profile count has a detail that catches teams out. Profiles include people and objects, so a company modelled as an object takes a profile as well, and under the billing rule in Customer.io’s docs a profile that exists at any point during the billing period counts toward that month’s bill even if you delete it. Cleaning the workspace after a big import therefore lowers next month’s bill, not this month’s. Customer.io also runs a Startup Program that gives companies that have raised under $10M a free first year, which is worth checking before you leave if you qualify.
What the alternatives cost at about 10,000 contacts
Platforms charge by different units, so the table lists each vendor’s own unit. Prices were read from the vendors’ pricing pages on October 7, 2026.
| Tool and plan | Unit | Monthly price at about 10,000 |
|---|---|---|
| Customer.io Essentials | Profiles (people and objects), billed monthly | $145 |
| Loops | Subscribers | $99 at 9,998 subscribers |
| Userlist Basic | Tracked users | $149 |
| ActiveCampaign Starter | Contacts, billed yearly | $149 |
| Kit Creator | Subscribers, billed yearly | $116 |
| MailerLite Comfort | Subscribers, monthly billing | $89 |
| Mailchimp Standard | Contacts, 5,001 to 10,000 band | $135 |
| Drip | People | $154 |
| Klaviyo Email | Profiles | $150 |
Only Loops, Kit and MailerLite are meaningfully cheaper than Essentials at this size. Mailchimp, Userlist, ActiveCampaign Starter, Drip and Klaviyo land within about $10 of it, so a move to any of them is a decision about the data model or who edits the journeys, not about savings. The free and low-cost plans in the entries below are better for a very small list, and the cheaper rows only stay cheaper if you can live without Customer.io’s deeper event logic, push and in-app channels.
Fourteen Customer.io alternatives at a glance
| Tool | Best for | Pricing context | Primary trade-off |
|---|---|---|---|
| Loops | Lean SaaS lifecycle email at a lower list price | Free for 1,000 newest contacts; $99 at 9,998 subscribers | It may be limiting when Customer.io’s event depth, complex branching, or additional channels such as push, in-app messaging and WhatsApp are essential. |
| Userlist | Company and account adoption | Basic $149 a month for up to 10,000 users; Professional $349 | Validate channel coverage and event flexibility if the current Customer.io setup depends on many custom behaviors. |
| ActiveCampaign | Scoring and visual automation run by marketers | Starter $15 a month at 1,000 contacts; $79 at 5,000 and $149 at 10,000 (billed yearly) | Contact-based economics and interface complexity need modeling at growth scale, and Starter allows only 1 user and 5 actions per automation. |
| Kit | Creator, coaching and course lists | Free up to 10,000 subscribers; Creator $116 a month for 10,000 subscribers (billed yearly) | It should not be selected for application notifications, account adoption, or complex SaaS telemetry. |
| HubSpot | CRM-owned lifecycle operations | Free tools; Marketing Hub Starter $7, Professional $800, Enterprise $3,600 a month (per seat) | The CRM suite adds cost and governance |
| MailerLite | Simple campaigns and nurture | Free for 250 subscribers; Comfort $89 a month for 10,000 subscribers (monthly billing) | It is not a substitute for real-time product-event eligibility or complex behavioral programs. |
| Brevo | Accessible email plus transactional sending | Free with 300 sends a day; Starter from $9 and Standard from $18 a month | Test event granularity, analytics, and suppression boundaries before moving sophisticated lifecycle logic. |
| Klaviyo | Commerce behavior and revenue flows | Free up to 250 profiles; Email plan $30 for 1,000 profiles, $150 for 10,000 profiles | Pure SaaS teams should verify that the commerce-first model does not make their product events awkward to represent. |
| Drip | Behavioral ecommerce retention | $39 a month for up to 2,500 people; $154 for 10,000 people; 14-day trial | It is a weak replacement for Customer.io if the application needs deep custom event orchestration or in-app channels. |
| Braze | Enterprise cross-channel engagement | No public price; billed on engaging users (quote-based) | Implementation, procurement, data engineering, and cost are substantially heavier than Customer.io for most smaller teams. |
| Resend | Developer-owned transactional email | Free 3,000 emails a month; Pro $20 for 50,000 emails; marketing $80 for 10,000 contacts | Multi-step lifecycle journeys with deep segmentation require another layer. |
| Postmark | Fast, isolated transactional delivery | Free for 100 emails a month; Basic $15 for 10,000 emails a month | It intentionally does not replace promotional or behavioral marketing automation. |
| Mailgun | API control and inbound parsing | Free 100 emails a day; Basic $15 and Foundation $35 a month | You will need to provide or pair the marketer-facing automation layer that Customer.io supplied. |
| SendGrid | High-volume API and marketing sending | Essentials from $19.95 and Pro from $89.95 a month; Marketing Campaigns free for 2,000 contacts | The split products and plan boundaries can create ownership confusion without a clear architecture. |
1. Loops
Best for: Lean SaaS lifecycle email at a lower list price. Loops is first because it is the closest like-for-like move for a small SaaS team that uses Customer.io for onboarding, product updates and a few lifecycle sequences, and does not use its deepest branching. Its slider reads $99 a month at 9,998 subscribers, where Customer.io Essentials is $145 for 10k profiles, and paid plans carry unlimited sends, transactional sending and no seat fees. It suits a team that values speed over maximal branching.
Trade-off: It may be limiting when Customer.io’s event depth, complex branching, or additional channels such as push, in-app messaging and WhatsApp are essential.
Moving from Customer.io: Switching means pointing your app’s existing event calls at Loops and rebuilding each campaign as a Loops sequence. Check how Loops represents the companies that Customer.io stored as objects before you cut over, and run both tools side by side on one journey first.
What it costs: The free plan sends up to 4,000 emails in any rolling 30 days to your 1,000 newest contacts. The paid slider reads $48 a month at 4,788 subscribers, $99 at 9,998 subscribers, $198 at 24,339 subscribers and $249 at 49,989 subscribers. At 49,989 subscribers that is $249 against $505+ for 50k+ profiles on Essentials, although profiles and subscribers are counted differently. See the Loops pricing page.
2. Userlist
Best for: Company and account adoption. Userlist is worth evaluating when the central object is a company, workspace, role, or account—not only an individual event stream. That makes it relevant for B2B onboarding, account health, and champion-led adoption programs. At 10,000 users it costs about what Customer.io does, so the reason to move is the data model, not the bill.
Trade-off: Validate channel coverage and event flexibility if the current Customer.io setup depends on many custom behaviors.
Moving from Customer.io: Map each Customer.io person to a Userlist user and each company object to a Userlist company, then compare your tracked-user count with your Customer.io profile count, because the two vendors count different things. The message allowance follows that user count, so the user count is the first number to settle.
What it costs: Basic is $149 a month for up to 10,000 users plus $10 for each additional 1,000, so 18,000 users costs $229. Professional is $349 at 10,000 users plus $12 per extra 1,000 and adds A/B split testing, conversion goals and advanced workflow features. Each plan includes a message allowance of 5 times your tracked users with a 500,000 floor, and extra messages are $1 per 1,000. See the Userlist pricing page.
3. ActiveCampaign
Best for: Scoring and visual automation run by marketers. ActiveCampaign is strong for branching nurture, lead scoring, and sales coordination. Teams leaving Customer.io because marketers, not engineers, now own the journeys may appreciate its mature visual automation interface and broad integrations.
Trade-off: Contact-based economics and interface complexity need modeling at growth scale, and Starter allows only 1 user and 5 actions per automation.
Moving from Customer.io: Product events become tags and custom fields, so list the Customer.io events each campaign listens for and decide which can be replaced by a form, an integration or a tag your app sets. Anything that reacted to an event within seconds needs a test in the new tool before you retire the old one.
What it costs: At 1,000 contacts, billed annually, Starter is $15 a month, Plus $49, Pro $79 and Enterprise $145. The contact selector reads Starter $79 and Plus $145 at 5,000 contacts, and Starter $149 and Plus $189 at 10,000. Starter is only offered up to 25,000 contacts; at 50,000 the page lists Plus at $609. See the ActiveCampaign pricing page.
4. Kit
Best for: Creator, coaching and course lists. Kit (formerly ConvertKit) is the right alternative when the business is run by a coach, course seller or consultant who set up Customer.io for a membership or course app but mostly sends broadcasts, launches and welcome sequences. The free plan covers forms, landing pages and broadcasts for up to 10,000 subscribers, and Creator adds Visual Automations and sequences. At 10,000 subscribers Creator’s $116 sits $29 under the $145 that Essentials charges for 10k profiles.
Trade-off: It should not be selected for application notifications, account adoption, or complex SaaS telemetry.
Moving from Customer.io: Kit offers free migrations and a 14-day trial with no credit card, so the cheapest test is to import one segment and rebuild the welcome sequence. Lesson-complete triggers and in-app messages from your course platform need a tag or integration to reach Kit, so list them before you commit.
What it costs: Set against Customer.io Essentials at $145 for 10,000 profiles, Kit Creator at the same size is $116 a month billed yearly, and at 5,000 it is $75 for Creator against $100 for Essentials. Past 10,000 the picture shifts: Creator reads $166 at 25,000 subscribers, while Kit Pro, the tier above it, is listed at $158 for 10,000 and $233 for 25,000. See the Kit pricing page.
5. HubSpot
Best for: CRM-owned lifecycle operations. HubSpot replaces Customer.io’s product-data emphasis with shared CRM context: lead ownership, pipeline stages, forms, and sales activity. It is a logical fit when marketing and sales need the same record and reporting model.
Trade-off: The CRM suite adds cost and governance; do not choose it solely to send a handful of product emails.
Moving from Customer.io: Decide first which Customer.io attributes become HubSpot properties, because events and objects do not arrive as CRM records on their own. Check the automation ceiling for the plan you can afford before you rebuild journeys: Starter allows up to 10 automated actions.
What it costs: Marketing Hub Starter is $7 a month, Professional $800 and Enterprise $3,600, priced per seat as HubSpot’s page reads, with free tools at no cost. Email automation allows up to 10 automated actions on Starter, unlimited on Professional and Enterprise, both listing omni-channel marketing automation; the free tools get 1 action. See the HubSpot pricing page.
6. MailerLite
Best for: Simple campaigns and nurture. MailerLite makes sense when the event graph is less important than newsletters, forms, welcome sequences, and an approachable editor. It lowers the operating burden for a generalist marketer, and at 10,000 subscribers Comfort is $56 a month below Essentials at 10k profiles.
Trade-off: It is not a substitute for real-time product-event eligibility or complex behavioral programs.
Moving from Customer.io: Nothing event-based migrates, so plan to replace API-driven triggers with forms, tags or an integration, and rebuild each campaign by hand. MailerLite states that its data storage center is in the European Union with ISO 27001 certification; Customer.io also lists US and EU data centers, so keep the region you chose.
What it costs: The free plan allows 250 subscribers, 2,500 emails a month and 2 seats. Comfort on monthly billing is $19 at 1,000 subscribers, $49 at 5,000, $89 at 10,000 and $179 at 25,000; Power is $39, $69, $129 and $239 at the same sizes. See the MailerLite pricing page.
7. Brevo
Best for: Accessible email plus transactional sending. Brevo can consolidate basic campaigns, automation, and transactional email for a cost-conscious team. Its appeal is operational simplicity when Customer.io’s data and channel model is more than the organization needs.
Trade-off: Test event granularity, analytics, and suppression boundaries before moving sophisticated lifecycle logic.
Moving from Customer.io: Brevo prices by the email volume you select rather than by profiles, so tally your monthly sends from Customer.io first. The free plan’s 300-a-day cap means a large broadcast has to be staggered while you test.
What it costs: The free plan sends 300 emails a day and stores up to 100,000 contacts. Starter starts at $9 a month and Standard at $18, both from 5,000 emails a month; Standard adds automation, A/B testing and advanced reports, and Professional starts at $499. See the Brevo pricing page.
8. Klaviyo
Best for: Commerce behavior and revenue flows. Klaviyo is a better fit than Customer.io when orders, catalog data, browsing, and customer value drive the journey. Its segmentation is designed around commerce behavior rather than general product telemetry.
Trade-off: Pure SaaS teams should verify that the commerce-first model does not make their product events awkward to represent.
Moving from Customer.io: Move only if you sell products to consumers: the work is connecting a store and rebuilding flows around orders. At 10,000 profiles Klaviyo’s Email plan is $150 against $145 on Essentials, so there is no saving to fund the effort.
What it costs: The free plan covers up to 250 active profiles and 500 emails a month. The Email plan is $30 a month for 1,000 profiles, $100 for 5,000 profiles and $150 for 10,000 profiles. See the Klaviyo pricing page.
9. Drip
Best for: Behavioral ecommerce retention. Drip is a focused choice for stores that want purchase, product-interest, and retention automation without adopting an enterprise platform. It can make commerce journeys easier for a lean team to operate.
Trade-off: It is a weak replacement for Customer.io if the application needs deep custom event orchestration or in-app channels.
Moving from Customer.io: Drip has no ongoing free plan, only a 14-day trial with no credit card, so rebuild one flow during the trial and decide on that. Customers who track subscription state rather than orders will find less to model.
What it costs: The entry tier is $39 a month for 1 to 2,500 people, then $49 at 3,000 people, $89 at 5,000 people, $154 at 10,000 people and $369 at 25,000 people on Drip’s pricing slider, with unlimited email sends and up to 50 workflows. See the Drip pricing page.
10. Braze
Best for: Enterprise cross-channel engagement. Braze is an enterprise alternative for organizations that need mobile, in-app, push, SMS, experimentation, and dedicated lifecycle operations. It is a scale and channel decision, not a simple email migration.
Trade-off: Implementation, procurement, data engineering, and cost are substantially heavier than Customer.io for most smaller teams.
Moving from Customer.io: Treat it as a project with a statement of work: the data pipeline, identity model and channel priorities come first, and templates come last. Leave it out if you are leaving Customer.io to spend less.
What it costs: Braze lists no price on its pricing page, which offers a trial request instead; its pricing article says billing follows the volume of users engaging with your brand and varies by edition, so pricing is on request (quote-based). See the Braze pricing page.
11. Resend
Best for: Developer-owned transactional email. Resend is relevant when Customer.io is being used mostly as an application mailer and developers want code-owned templates and a clean API. It can simplify notifications, receipts, and authentication email, and its Marketing tab covers simple broadcasts and automations.
Trade-off: Multi-step lifecycle journeys with deep segmentation require another layer.
Moving from Customer.io: Customer.io includes transactional email in every plan, so moving it to Resend adds a second bill and a second sending domain to set up. Move the transactional stream first and leave marketing journeys where they are until it is stable.
What it costs: The free plan covers 3,000 emails a month and 100 a day. Pro is $20 a month for 50,000 emails and $35 at 100,000; Scale is $90 for 100,000 and $160 at 200,000. The Marketing tab is free at 1,000 contacts with 10,000 automation runs, and reads $40 at 5,000 contacts and $80 at 10,000. See the Resend pricing page.
12. Postmark
Best for: Fast, isolated transactional delivery. Postmark specializes in critical transactional messages and separates streams to protect deliverability. It is useful when the reason for leaving Customer.io is a desire for a dedicated delivery system.
Trade-off: It intentionally does not replace promotional or behavioral marketing automation.
Moving from Customer.io: Create separate message streams for transactional and broadcast mail before you send anything, so receipts and password resets are never held up by a campaign. Keep your Customer.io journeys until a lifecycle tool replaces them.
What it costs: The free plan covers 100 emails a month. Basic is $15 for 10,000 emails with extra emails at $1.80 per 1,000, Pro is $16.50 and Platform $18 for the same 10,000. The slider reads $55, $60.50 and $66 at 50,000 emails and $115, $126.50 and $138 at 125,000. See the Postmark pricing page.
13. Mailgun
Best for: API control and inbound parsing. Mailgun fits engineering-led teams that need logs, domain controls, validation, inbound parsing, and programmable delivery. It gives application owners direct control over infrastructure.
Trade-off: You will need to provide or pair the marketer-facing automation layer that Customer.io supplied.
Moving from Customer.io: The job is re-pointing your sending to an API and SMTP relay, then keeping a marketer-facing tool for campaigns. Log retention is short on the lower plans, so check how long you need delivery logs before you pick one.
What it costs: The free plan sends 100 emails a day with 1 custom sending domain. Basic starts at $15 a month for 10,000 emails (extra from $1.80 per 1,000), Foundation is $35 a month after the first month for 50,000 emails, and Scale is $90 a month after the first month for 100,000 emails with 5,000 validations included. See the Mailgun pricing page.
14. SendGrid
Best for: High-volume API and marketing sending. SendGrid is worth considering when delivery volume, ecosystem breadth, and separate API and campaign workflows matter. It can support a more traditional division between engineering and marketing operations.
Trade-off: The split products and plan boundaries can create ownership confusion without a clear architecture.
Moving from Customer.io: Decide which product owns which message: the Email API handles application mail, and Marketing Campaigns handles broadcasts with its own contact limits. Name the owner of each before the cutover so a message is not sent from both.
What it costs: The Email API has a free trial of 100 emails a day for 60 days, then Essentials from $19.95 a month (the selector shows 50,000 to 100,000 emails) and Pro from $89.95. Marketing Campaigns has a free plan for up to 2,000 contacts and 6,000 emails a month, Basic from $15 and Advanced from $60. See the SendGrid pricing page.
What to inventory before you leave Customer.io
Leaving is mostly a question of what Customer.io currently does that the new tool will not. Go through this list while the old workspace is still running, and keep it running until every row passes.
| Customer.io feature in use | What to check in the new tool | Pass condition |
|---|---|---|
| People and objects (Essentials includes 2 object types, Premium 10) | Whether companies, workspaces or courses have a home, or become tags and fields | A test person lands in the right company with the right role |
| Events that trigger campaigns | That your app can send the same events, and how fast they take effect | A test event starts the journey and the exit event stops it within the same day |
| Push, in-app messaging, WhatsApp or SMS | That each channel exists in the new tool, or is dropped on purpose | A written list of channels you are keeping and the ones you are retiring |
| Transactional email, included in every Customer.io plan | Whether it moves to the new tool or to Postmark or Resend, with its own domain set-up | Receipts and password resets still arrive after DNS changes |
| US or EU data centers and the DPA | The new vendor’s data region and data processing terms | The region you promised customers is the region you still use |
| Managed deliverability (Premium and above) | Who watches bounces, complaints and sender reputation after the move | A named owner and a dedicated or shared sending domain warmed up before the cutover |
Verdict
Start with Loops if you want the same kind of tool at a lower price and your journeys are mostly onboarding and product updates. Choose Userlist if your customers are companies and you need admins treated differently from teammates, ActiveCampaign if marketers need to edit the journeys without a developer, and Kit if you are a coach or course seller who mostly sends launches and welcome sequences. Use Resend or Postmark when what you need is a transactional channel, HubSpot only when sales and marketing share a CRM, and Braze only when you need mobile, in-app and push at enterprise scale; our Customer.io vs Braze comparison sets those two side by side.
Stay on Customer.io if reactive journeys driven by your own product events are the point and the bill is no longer the problem. Its $100 starting price includes 1 million emails a month, so a growing list is the thing to watch, not the email volume. If you do move, plan for one overlapping month: a profile that existed in Customer.io during a month counts toward that month’s bill even after you delete it, so deleting people at the cutover will not lower that month’s invoice. The customer-success guide and the creator guide compare the same tools for the two audiences that most often leave.
Decision table: who should switch to what?
| If you are leaving Customer.io because… | Test first | Confirm before committing |
|---|---|---|
| The profile bill grows faster than revenue | Loops, Kit or MailerLite | That each tool’s unit (subscribers, not profiles) matches how you count your audience |
| You manage companies, not just people | Userlist | That your app can send a company identifier with each user |
| Marketers want to edit journeys without a developer | ActiveCampaign Plus or Starter | The 5-action limit per automation on Starter |
| You run launches and courses to a list | Kit Creator, with a 14-day trial | That your course platform can tag a student when a lesson is complete |
| Sales and marketing share one record | HubSpot free tools, then Professional | The automation ceiling: up to 10 actions on Starter, unlimited on Professional |
| You mainly need transactional email | Postmark or Resend | That password resets and receipts move first, on their own sending domain |
| You sell products and need order-based flows | Klaviyo or Drip | That the store connects natively, and that $150 for Klaviyo or $154 for Drip at 10,000 contacts beats your current bill |
| You need mobile, in-app and push at scale | Braze, by quote | The definition of an engaged user in the quote, and implementation cost |
A four-week cutover from Customer.io
The safest order keeps Customer.io live until the new tool has carried one real journey, so no customer goes without a welcome or a receipt.
| Week | What you do | Done when |
|---|---|---|
| 1 | List every active campaign and broadcast, the events and attributes each one uses, and the channels it sends on | You can say which journeys are email only and which use push, in-app or WhatsApp |
| 2 | Price your two finalists at your profile or subscriber count and at double it, and send the same test events from your app to each | The events show on a test person in the new tool with the correct company or tags |
| 3 | Rebuild the most important journey, usually onboarding, and run it for new sign-ups only while Customer.io keeps serving everyone else | A new sign-up is in the new tool, and nobody receives the same email from both |
| 4 | Move the remaining journeys and transactional mail, switch your DNS and sender identity, and then cancel the old plan | A week passes with no duplicate sends, and bounces and complaints look like the old tool’s |
What a good pilot actually measures
| Measurement trap | Why it misleads when you switch | Fix |
|---|---|---|
| Comparing price per profile with price per subscriber | Customer.io counts people and objects, while Loops, Kit and MailerLite count subscribers, so the units are not equal | Count the same audience in each tool’s unit before you compare the bills |
| Trusting the new tool’s sample data | A dashboard with demo contacts hides timing and merge problems that real events show | Send real events from your app to a test person in the new tool |
| Judging on the free plan | Kit’s free plan has no sequences and Loops’ free plan reaches only your 1,000 newest contacts | Run the trial on the paid tier you would actually buy |
| Cancelling at cutover | Deleted profiles still count for the month they existed in | Plan one overlapping month and compare activation rates for the same cohort |
Common implementation mistakes to avoid
- Exporting people but not unsubscribes and suppressions, so someone who opted out of Customer.io gets mailed from the new tool
- Leaving the same journey running in both tools after the cutover, so a new user gets two welcome emails
- Moving transactional email without warming a new sending domain, which puts receipts and password resets at risk
- Choosing a cheaper tool and discovering later that the event your journey depends on has no equivalent trigger there

FAQ
What is the best alternative to Customer.io?
For a small SaaS team that wants the same kind of tool for less, Loops: $99 a month at 9,998 subscribers against $145 for 10k profiles on Customer.io Essentials. For company-level accounts it is Userlist ($149 for up to 10,000 users), for marketer-run journeys ActiveCampaign, and for coaches and course sellers Kit.
How much does Customer.io cost?
Essentials starts at $100 a month for 5k profiles, billed monthly, with $145 at 10k, $235 at 20k and $505+ at 50k and above, plus $0.009 per extra profile. Premium starts at $1,000 a month, billed yearly, with custom profile volume.
Does deleting profiles lower my Customer.io bill?
Not for the current month. Customer.io counts a profile toward the bill for any month in which it existed, even if you delete it, so a clean-up lowers the following month’s bill.
Is there a cheaper Customer.io alternative for a coach or course seller?
Yes. Kit is free up to 10,000 subscribers for forms and broadcasts, and Creator is $116 a month at 10,000 subscribers, billed yearly. MailerLite Comfort is $89 at the same size on monthly billing. Both lack Customer.io’s event-driven depth, which a launch-and-welcome-sequence business rarely uses.
