The Verdict

Postmark wins if all you need is reliable, fast transactional email and you don't mind paying from day one. Brevo is the better default for small teams that also want marketing campaigns, automation, and SMS without juggling separate tools and bills. If you're purely sending receipts and password resets at scale, stick with Postmark; if you're a small business doing both marketing and transactional email, Brevo's free tier and all-in-one design will save money.

How to switch from Postmark to Brevo

1Export your Postmark message history and template content: pull activity data via the Activity API or CSV export on the Activity page, and copy each custom template's HTML/CSS manually or via the Templates API since there's no bulk export.
2Sign up for Brevo and verify your sending domain (SPF, DKIM, DMARC records) to protect deliverability during the transition.
3Recreate your Postmark templates in Brevo's template editor, or import the raw HTML you exported and adjust merge tags to Brevo's syntax.
4Update your application's SMTP credentials or API keys to point to Brevo's SMTP relay or REST API, and re-test all transactional triggers (signup, password reset, receipts) in a staging environment.
5Set up any marketing automation, contact lists, and segmentation in Brevo that Postmark didn't support, migrating subscriber data via CSV import.
6Run both services in parallel for one billing cycle, monitor deliverability and bounce rates in Brevo, then fully cut over and cancel your Postmark plan.

Postmark vs Brevo: common questions

How do I export my data from Postmark before switching?+

Postmark doesn't offer a one-click full account export — you pull data via their Activity API or CSV exports from the Activity page (bounces, opens, message history) per message stream. Templates need to be copied manually or pulled via the Templates API since there's no bulk export button. Budget a few hours if you have many custom templates or years of message history you want archived.

What features do I lose moving from Postmark to Brevo?+

You lose Postmark's message stream separation and its especially fast, dedicated transactional delivery speed — Brevo mixes transactional and marketing traffic more than Postmark's purpose-built architecture. Postmark's bounce/spam analytics are also more granular. You gain marketing campaigns, automation, and SMS in exchange, so it's a net feature increase if you need those.

Is Brevo's free plan enough for a small team?+

If you send under 300 transactional/marketing emails per day combined, yes — the free plan covers most early-stage startups and small businesses. Once you're consistently sending password resets, receipts, and newsletters together, you'll likely hit the daily cap and need to upgrade to a paid tier starting around $25/month.

Does Brevo support the same integrations as Postmark?+

Both have SMTP and REST APIs that work with most frameworks and platforms (Rails, Django, Node, WordPress plugins, Zapier). Brevo has broader native integrations for e-commerce (Shopify, WooCommerce) since it's marketing-focused, while Postmark has deeper webhook support tailored to transactional event tracking. Most common app integrations exist on both, but check your specific stack before switching.

Will switching from Postmark to Brevo actually save money long-term?+

For low-to-moderate volume senders (under a few thousand emails/month) who also need marketing email, yes — you'd otherwise pay for Postmark plus a separate marketing tool like Mailchimp. At high transactional volume with no marketing needs, Postmark can be cheaper per email since Brevo's paid tiers bundle features you may not use. Run your actual monthly email volume through both pricing pages before deciding.
