Sequenzy vs MailerLite for Startups: Free Plans, Costs and Fit
Sequenzy vs MailerLite for startups: free plans, prices at five list sizes, and which tool fits billing-driven SaaS lifecycle email versus newsletter-first sending.
For a startup whose emails are triggered by subscription events, such as a trial that starts, a plan upgrade or a failed card payment, Sequenzy is the better pick of these two. It connects to Stripe, Paddle and Lemon Squeezy, lets those billing events start automated flows, and its paid plans are priced by monthly email volume: the 15,000-email plan costs $19 a month, or $205 a year, and the free plan covers 2,500 emails a month. For a startup that mostly sends a newsletter to a list that is still small, MailerLite is the cheaper choice, because its Free plan covers up to 250 subscribers and 2,500 emails a month at $0.
The rest of this page explains where the line falls. It covers the free plans, the cost at five realistic list sizes, what each tool does well for a startup, where each one falls short, and how to move a list from one to the other without losing consent records or the automations that matter most.
Prices in this comparison are the ones listed on each vendor's pricing page, as checked on 7 October 2026. Sequenzy charges by emails sent and includes unlimited contacts and sending domains on every plan. MailerLite charges by subscriber count, and its monthly email allowance depends on the subscriber tier. Because the two models count different things, the cost comparison below uses the same list and send patterns for both tools.
Who this comparison is for
This page is written for founders and small teams who have to pick an email platform before they have a large list. Most of them fall into one of two groups. The first group runs a software product with monthly or annual subscriptions. Its email is tied to what happens inside the billing system: a customer starts a trial, pays, downgrades, cancels or fails to pay. The second group is closer to a publisher or a service business. It sends a newsletter, a product update or an occasional offer to people who signed up on a website, and billing has little to do with the sends. Sequenzy is aimed mainly at the first group. MailerLite is aimed mainly at the second. Neither product is limited to its audience, and a few startups sit between the two. The sections below explain how to tell which group you are in and which tool follows from it.
The two tools at a glance
The table below sets the core facts side by side. The starting prices are the lowest paid plans on each vendor's pricing page. The free plans are listed separately because their limits decide most early choices.
| Tool | Best for | Entry price (plan and billing) | Main limitation |
|---|---|---|---|
| Sequenzy | SaaS startups that send billing-triggered lifecycle and transactional email | Free plan at $0 for 2,500 emails a month. Paid: 15,000 emails a month at $19 a month (monthly billing) or $205 a year | Price rises with the number of emails sent, not the number of contacts, so frequent sends to a large list move you up the plan ladder quickly |
| MailerLite | Newsletter-first startups and solo founders with a small list that is growing steadily | Free plan at $0 for up to 250 subscribers and 2,500 emails a month. Paid: Comfort from $12 a month (monthly billing) or $10.80 a month billed yearly | The free plan stops at 250 subscribers, and the price for larger lists depends on the subscriber tier, so it has to be looked up for each list size |
Two things stand out in this table. Sequenzy's free plan is set by sends, so a startup with a list of a few hundred people that emails weekly can stay free. MailerLite's free plan is set by subscribers, so the same startup can hit the 250-subscriber ceiling before it hits the 2,500-email ceiling. Growth affects the two tools in different ways, and the cost table further down shows the effect at specific sizes.
Free plans compared
Both vendors offer a free plan, and for a pre-revenue startup it is usually the first thing to test. The limits are different enough that the same list can fit one and not the other.
Sequenzy's free plan allows 2,500 emails a month. Its pricing page also says contacts and sending domains are unlimited on every plan, including the free one. That means a startup with a list of 1,000 people can send two emails to all of them in a month and stay free, and it can grow the list without changing the plan until its monthly sends pass 2,500. Because the free plan is not limited by subscriber count, it is a practical option for a SaaS team that is still building its product and wants a welcome sequence, onboarding emails and a few announcements without paying for a tool yet.
MailerLite's free plan covers up to 250 subscribers and 2,500 emails a month. Those two limits apply together. A list of 250 people who each receive ten emails a month would use the full monthly allowance, so the free plan suits a small list that is sent to sparingly. Once the list passes 250 subscribers, the free plan no longer applies, and the first paid option is the Comfort plan.
The practical rule is this. If your list will stay under 250 people for the next few months and you send a single newsletter, the MailerLite free plan is hard to beat. If your list is already in the hundreds or will be soon, and your sends include automated emails that follow customer behaviour, the Sequenzy free plan is usually the better starting point, because the limit it sets is on volume rather than on the size of the list.
What each tool costs at five list sizes
The following table takes five realistic startup profiles and shows what each tool charges for them. The email counts are simple arithmetic: contacts multiplied by the number of sends in the month. Where a vendor does not publish a price for that list size on its pricing page, the table says so and does not estimate one.
| Startup profile | Emails per month | Sequenzy plan and price | MailerLite plan and price |
|---|---|---|---|
| 200 contacts, 2 sends a month | 400 (200 × 2) | Free plan, $0 (2,500 emails a month) | Free plan, $0 (under 250 subscribers, under 2,500 emails) |
| 500 contacts, weekly sends | About 2,170 (500 × 52 ÷ 12) | Free plan, $0 (under the 2,500-email limit) | Comfort plan, $12 a month (monthly billing) or $10.80 a month billed yearly, which is $129.60 a year |
| 5,000 contacts, 4 sends a month | 20,000 (5,000 × 4) | 30,000-email plan, $29 a month or $313 a year | Pricing on request for lists above the Comfort starting tier |
| 25,000 contacts, 2 sends a month | 50,000 (25,000 × 2) | 60,000-email plan, $49 a month or $529 a year | Pricing on request |
| 100,000 contacts, 1 send a month | 100,000 (100,000 × 1) | 120,000-email plan, $99 a month or $1,069 a year | Pricing on request |
Three observations follow from the table. First, at the 500-contact weekly profile the Sequenzy free plan costs nothing, while the lowest MailerLite paid plan costs $10.80 a month when billed yearly, or $129.60 a year. That gap is the clearest case for Sequenzy at a small size, provided the send volume stays under 2,500 emails a month. Second, the Comfort plan's monthly allowance is ten times its subscriber ceiling, which is 5,000 emails a month for a 500-subscriber tier. A 500-contact list sent weekly is well inside that allowance. The cost question for MailerLite at this size is the subscriber count, not the send count. Third, above 500 subscribers the MailerLite price is set by the subscriber tier on its pricing page, and the rows for 5,000 contacts and above say "pricing on request" because this comparison does not publish a figure for them. Anyone choosing between the two at those sizes should request a quote from MailerLite and compare it with the Sequenzy plan in the table.
The Sequenzy yearly prices in the table are the totals listed on its pricing page. Billed monthly, the 15,000-email plan would cost 12 × $19 = $228 over a year. Billed yearly, it costs $205, which is $23 less. The 30,000-email plan is 12 × $29 = $348 monthly, against $313 yearly. For MailerLite's Comfort plan, 12 × $12 = $144 monthly, against $129.60 billed yearly.
Sequenzy for startup lifecycle email
Sequenzy is built around the idea that a SaaS company's most useful emails follow what a customer does with the product and the bill. Its pricing page describes it as a unified transactional and marketing email platform, so one API, one dashboard and one bill cover receipts, product notifications and newsletters. For a small team that would otherwise run one service for transactional email and another for marketing, that consolidation is the main practical argument.
The billing integrations are the feature most relevant to the startups this page is about. Sequenzy lists Stripe, Paddle and Lemon Squeezy among its payment integrations, along with Polar, Creem and Dodo Payments. Connecting one of them lets subscription events start automations. A trial that begins can trigger an onboarding series. An upgrade can trigger a message about the features in the new plan. A cancellation can trigger a short survey. Each of these flows can be targeted using plan, revenue and engagement data, which Sequenzy's product description says it uses to build segments.
Payment failures get specific attention. Sequenzy documents a payment-event trigger, saas.payment_failed, which includes a hosted invoice URL. That URL points to a page where the customer can pay the invoice or update their card. A startup can use the event to send a message that links straight to the page where the fix happens, rather than sending a generic reminder. This page does not quote a recovery rate for it, because the vendor does not publish one in the material used here, and a startup should measure its own results after launch. Revenue attribution and goal tracking are also listed on Sequenzy's pricing page as included on each plan. For a founder who wants to see which sequence brought in paying customers, this turns email from an activity into a measurable channel. The limit is that attribution depends on the billing connection and on how goals are set up, so it works best when the billing integration is in place from the start.
Where Sequenzy falls short for a startup
The first limitation is cost growth with send volume. Because the plan is set by emails sent, a startup that wants a weekly newsletter to a large list, and also runs several automated sequences, can move up the plan ladder faster than the contact count would suggest. The 120,000-email plan at $99 a month is a reasonable price for that volume, but a team with a big list should model its monthly sends before choosing a plan, not after. The second limitation is scope. Sequenzy is built around email and the automations that drive it. Its listed features do not include landing pages or a website builder, so a startup that wants to create signup pages inside the same tool will need a separate page builder and will connect it to Sequenzy. For a SaaS product where signup happens in the app, this is usually not a problem. For a company that sells through simple marketing pages, it is one. The third limitation is the SMS add-on. Sequenzy lists an SMS and MMS add-on, but the price of that add-on is not part of this comparison, so a team that plans to use SMS should look up its cost before deciding.
MailerLite for newsletter-first startups
MailerLite is a better fit for a startup whose main email is a newsletter or a content series sent to a list of people who opted in through a website. Its free plan is useful for a company that is still deciding whether email will be a core channel, and its Comfort plan is one of the lower-priced paid options for a list of a few hundred subscribers. The yearly billing option brings the Comfort price down from $12 to $10.80 a month, which is a 10 percent reduction on the monthly rate.
MailerLite also includes landing pages and forms, according to its own description. For a startup that needs a signup page, a lead magnet and a confirmation flow in one tool, that combination removes a step. A founder who is building an audience before the product exists can set up the list, the form and the welcome email in one place, and the lower cost of the early tiers keeps the setup inexpensive.
Where MailerLite falls short for a SaaS startup
The first limitation is billing. This comparison does not treat MailerLite as having a native billing connection of the kind Sequenzy describes for Stripe, Paddle and Lemon Squeezy. A SaaS team that wants trial, upgrade and failed-payment emails from MailerLite would have to connect its billing system through a third-party automation tool or a custom webhook. Zapier is one route. Its free plan includes 100 tasks a month, and its Professional plan starts at $19.99 a month. Each successful action in a Zap uses tasks, so a busy billing account can use up the free allowance quickly. The MailerLite integrations page lists the connectors it supports, and that list is the place to see what is available at any point in time. The second limitation is transactional email. In this comparison MailerLite is a marketing tool, and transactional sends such as receipts, password resets and invoice notices are handled by a separate product. A startup that wants one platform for both kinds of email will find Sequenzy better suited to that goal. The third limitation is the way the free plan scales. Because the free plan is capped at 250 subscribers, a startup that grows its list quickly will reach the paid tiers sooner than it would reach the paid tiers of a sends-based plan. That is not a problem in itself, but it changes the budget from the first month of growth.
Choosing between them
The choice comes down to three questions. What triggers your emails: a billing event or a calendar? How many people are on the list today, and how many will there be in six months? And do you need landing pages, billing sync or both? The decision table below turns these questions into direct recommendations.
| If you need | Pick | Because |
|---|---|---|
| Emails triggered by subscription events from Stripe, Paddle or Lemon Squeezy | Sequenzy | Those billing platforms are listed as native integrations, and the events can start automations directly |
| Free sending for a list under 250 people | MailerLite | The free plan covers up to 250 subscribers and 2,500 emails a month at $0 |
| Free sending for a list of about 500 with weekly emails | Sequenzy | The free plan allows 2,500 emails a month, which covers about 2,170 emails in that pattern, while MailerLite's lowest paid plan starts at $12 a month |
| Landing pages and forms in the same tool | MailerLite | MailerLite includes landing pages and forms, which Sequenzy's listed features do not cover |
| Revenue attribution by email sequence | Sequenzy | Revenue attribution and goal tracking are listed as included on every Sequenzy plan |
| Large list with frequent sends and a budget set by volume | Sequenzy | The price is set by emails sent, so the 120,000-email plan at $99 a month covers 120,000 emails in a month; MailerLite pricing above the Comfort tier needs a quote |
| One platform for transactional and marketing email | Sequenzy | Sequenzy describes transactional and marketing email in one platform, while MailerLite treats transactional email as a separate product |
One pattern is worth noting. A startup that is still pre-revenue, has a small list and sends a newsletter can start with MailerLite's free plan at no cost and move to Sequenzy later, once the product has billing events worth automating. The reverse path is less common, because a team that starts with billing-triggered flows usually wants them from day one.
Migrating between the two
Moving a list is mostly a question of keeping consent and history intact. A list that was built on a signup form carries an opt-in record for each person, and any move should preserve it. The same goes for tags and groups that drive segments, because they are what makes an automation send the right message to the right people. The table below sets out a migration in order. The steps are the same in either direction, with the names of the platform screens changed.
| Step | What to do | Why it matters |
|---|---|---|
| 1. Export | Export every subscriber or contact with email address, signup date, opt-in source and any tags or groups | Opt-in evidence and tags are the two things that are hard to rebuild later |
| 2. Map segments | Write down which tags or groups drive which emails, then recreate each one as a segment on the new platform | Segments are the logic behind onboarding, upgrade and re-engagement flows |
| 3. Connect billing | On Sequenzy, connect Stripe, Paddle or Lemon Squeezy. On MailerLite, set up the connector your billing system supports | Billing events are what turn a generic list into a lifecycle program |
| 4. Rebuild the core flows | Rebuild the welcome, trial, payment-failed and cancellation flows first, then the newsletter | These are the emails customers receive most often and the ones that affect revenue |
| 5. Run both briefly | Send a small test segment through the new platform while the old one still runs the rest of the list | A short parallel run exposes broken links, missing merge fields and suppression problems before the full switch |
| 6. Cut over and close | Move the full list, confirm the last send from the old platform, then cancel the old plan | Cancelling before the last send can leave flows half-finished, and paying for two platforms for a month costs more than a short overlap |
When moving from MailerLite to Sequenzy, the practical risk is the billing connection. Trial and upgrade flows should be rebuilt on Sequenzy's payment-event triggers rather than copied from a Zapier chain, so the new setup does not depend on tasks counted in a separate tool. When moving from Sequenzy to MailerLite, the risk is losing the payment-event logic, so the team should decide in advance how failed-payment and cancellation emails will be sent, whether through a connector or a webhook.
A setup plan for a startup starting from zero
A startup that has no list yet can avoid most migration work by choosing the right tool at the start. Here is a simple sequence. Begin with the free plan that matches your first 90 days. For a SaaS product that will take payments from day one, connect the billing platform before the first customer signs up, so that trial and onboarding emails start with real data. For a content or newsletter business, set up the signup form and the welcome email before publishing anything, so every subscriber gets the same consent language and the same first message. Keep a single list of every automation you rely on, with the trigger and the goal for each. A founder who can explain each flow in one sentence will find it easier to move to a higher plan or change tools, because the requirements are already written down. Review the list each quarter, and remove any automation that no longer has a clear goal. This habit keeps the send count low, which matters for Sequenzy's volume-based pricing, and keeps the subscriber count honest, which matters for MailerLite's tier pricing.
Finally, measure what changes after the switch. Open rates and click rates are easy to see, but for a SaaS startup the more useful numbers are trial-to-paid conversion, failed-payment recovery and the rate of cancellations after onboarding. Sequenzy's revenue attribution can connect email sends to those outcomes when the billing connection is in place. With MailerLite, the same questions require exporting data and joining it in a spreadsheet or in a separate analytics tool. Neither approach is wrong, but the effort is different, and that difference should be part of the decision.
Frequently asked questions
Is Sequenzy free to start?
Yes. Sequenzy's free plan allows 2,500 emails a month. Its pricing page also lists unlimited contacts and sending domains on every plan, so the free allowance is set by monthly sends rather than by the size of the list.
Can MailerLite's free plan handle a list of 1,000 people?
No. The MailerLite free plan covers up to 250 subscribers and 2,500 emails a month. A list of 1,000 people needs a paid plan, and the price for that size is on request.
Which tool is cheaper for a list of 500 people sent weekly?
On the figures in this comparison, Sequenzy's free plan is cheaper, because 500 people emailed weekly is about 2,170 emails a month, which fits within the 2,500-email free allowance. MailerLite's lowest paid tier, Comfort, starts at $12 a month on monthly billing, or $10.80 a month billed yearly.
Does Sequenzy help recover failed payments?
Sequenzy provides a payment-event trigger, saas.payment_failed, which includes a hosted invoice URL. That link goes to a page where the customer can pay the invoice or update their card, and a payment-failed flow can send a message that points to it. This page does not state a recovery rate, and the outcome depends on the product, the customers and the message.
Does MailerLite connect directly to Stripe?
This comparison does not list a native Stripe connection for MailerLite. A billing system can reach MailerLite through a third-party tool such as Zapier or through a custom webhook. The MailerLite integrations page shows the connectors it currently supports.
Is paying yearly cheaper on both tools?
Yes, on the plans where the vendor publishes a yearly price. Sequenzy's 15,000-email plan costs $205 a year billed yearly, against $228 billed monthly, a difference of $23. MailerLite's Comfort plan costs $10.80 a month billed yearly, which is $129.60 a year, against $144 billed monthly.
Can I move my list from one tool to the other without losing subscribers?
Yes, in most cases. Export each contact with the email address, the signup date, the opt-in source and any tags or groups, then import them into the new platform and recreate the segments. Keep the old account running until the last send has gone out, so no flow is cut in the middle.
Which should a pre-launch startup pick?
A pre-launch startup with a small list and a newsletter should start with the free plan that fits its list. If the product will take payments soon and the team wants trial and payment emails from the first customer, start with Sequenzy's free plan and connect the billing platform before launch. If the team wants a signup page and a newsletter with no billing logic, MailerLite's free plan is the simpler start.
