# Mailgun vs Postmark for Next.js

Both are email batteries. A repo takes one of them, not both.

| | Mailgun | Postmark |
| --- | --- | --- |
| What it is | Transactional email through Mailgun, behind one provider-agnostic send function. React Email templates are rendered to HTML before sending. Suppression lists are read straight from Mailgun's own API. Mail routes to the EU or US region, and the event webhook is signature-verified. | Transactional email through Postmark, behind one provider-agnostic send function. React Email templates are rendered to HTML and text before sending. Transactional and broadcast mail use separate message streams. The suppression list is mirrored from Postmark's own. A basic-auth webhook handles bounces, spam complaints and subscription changes. |
| Pricing | Free plan: 100 emails a day and 1 custom domain. Basic starts at $15/month for 10,000 emails. Foundation is $35/month for 50,000 and Scale $90/month for 100,000. Logs are kept 1 day on Free and Basic, 5 days on Foundation and 30 days on Scale. | Free developer plan: 100 emails a month, no expiry. Paid plans start at $15/month for 10,000 emails. Every plan keeps 45 days of message history by default. Dedicated IPs (from $50/month) and longer retention are add-ons. |
| Best for | Teams that need EU data residency, or want suppression and analytics held by the provider instead of their own database. Also teams sending enough volume to care about dedicated IPs and warm-up support. And the pragmatic choice when an existing system already speaks Mailgun. | Products where the transactional mail has to arrive now: sign-in links, password resets, receipts. Also teams that send some marketing and want it kept on separate infrastructure from the mail that must not fail. |
