Choose Brevo when a larger stored contact base, send-volume pricing or combined marketing and transactional email matters. Choose MailerLite when the main job is a conventional newsletter with forms, landing pages and visual automation priced around active subscribers. Calculate your expected list and sends on both before deciding.
- Best for
- Brevo: send-volume-led service businesses. MailerLite: small publications and creators wanting a focused newsletter workflow.
- Not suitable for
- Purchased lists, cold bulk campaigns or anyone selecting a platform without recording consent and future paid-tier costs.
- Bottom line
- Brevo wins on a larger low-frequency database; MailerLite is often simpler for a small newsletter. The exact winner changes with list size and cadence.
- Brevo Free documents 300 daily sends and up to 100,000 stored contacts; MailerLite Free documents 250 active subscribers and 2,500 monthly sends.
- Brevo's paid entry tiers center monthly email volume and contact capacity; MailerLite scales more directly with active subscribers and plan features.
- Both products document double opt-in, but consent wording, evidence and unsubscribe handling remain the publisher's responsibility.
- This is an independent non-affiliate comparison with no deliverability or interface testing.

When Brevo is the better choice
Brevo fits a business that stores many opted-in contacts but sends relatively selectively. The Free daily limit can support testing and small automated flows, while paid plans remove the daily cap and sell monthly send tiers.
The platform also includes transactional email and other communication channels. That can reduce the number of providers for a website that needs password-reset or order messages alongside newsletters. Keep marketing consent and transactional necessity separate even when the same provider sends both.
Brevo's Standard tier becomes relevant when broader automation, A/B testing, advanced reports and landing-page features matter. Do not assume every feature is in Starter; check the current account comparison.
When MailerLite is the better choice
MailerLite offers a familiar newsletter workflow: subscribers, groups, forms, landing pages, campaigns and visual automations. The Free tier is enough to test a small list and welcome flow, but sending locks when the active-subscriber ceiling is exceeded.
Paid plans scale by subscriber tier and plan. Comfort provides a broader small-team toolkit with bounded sends and automations; Power emphasizes unlimited sending under fair-use terms and wider automation/form allowances. Exact allowances depend on the current tier.
MailerLite can be easier to forecast when list size and newsletter cadence are the primary variables. Brevo can be easier when stored contacts are high but messages are less frequent.
Compare at three realistic list sizes
Do not compare only the smallest card. Price both tools at:
- the current active, consented list;
- the expected list in six months;
- the list after a successful year.
Calculate monthly sends as:
active subscribers × newsletters + automation messages + tests + resends
A list of 1,500 receiving four newsletters already needs 6,000 sends before automation. A 300-per-day cap cannot deliver that newsletter in one day. A subscriber-based tool may send it easily but move into a higher paid tier as the list grows.
Forms and double opt-in
Brevo's form builder documents GDPR fields, multi-list choices, consent groups on eligible plans and double confirmation. MailerLite documents double opt-in for its forms and API routes. Both allow a subscriber to confirm an email before activation.
Use a form that states:
- who sends the messages;
- what content and approximate frequency to expect;
- why the email address is collected;
- a link to the privacy notice;
- that unsubscribe is available;
- separate choices for materially different purposes.
Do not pre-tick marketing consent. Store the form version, source, timestamp and confirmation evidence. Consult appropriate legal advice for the actual jurisdiction.
Automation and segmentation
Start with one welcome message and one simple follow-up. Every branch should have an entry rule, exit rule and suppression rule for unsubscribed or invalid contacts. Test with separate addresses before enabling it for the full list.
Avoid using opens as a definitive measure of interest because privacy features can affect tracking. Use a combination of confirmed clicks, replies, conversions and subscriber preferences where appropriate.
Sending-domain setup
Authenticate the sender domain using the exact records supplied by the chosen provider and verify them in the provider interface. DNS changes should be made only by the authorized domain owner after checking for conflicting records. Use a branded From address the organization controls; never invent an address for a public site.
The software connection does not replace a privacy notice, consent log, unsubscribe process or content plan.
Migration considerations
Before moving platforms, export active, unsubscribed, bounced and suppressed records separately. Preserve suppression status so old unsubscribes are not accidentally reactivated. Recreate forms and automations in test mode, authenticate the new sender and import only permitted contacts.
Send a small monitored campaign before moving the full cadence. Keep the old account long enough to verify required records and then follow its retention and deletion process.
