The Mailgun alternative built for modern teams
Mailgun is powerful but complex and no longer free. Sendbound gives you the same deliverability with a modern API, React Email support, and 3,000 free emails per month.
Built for a better email experience
Mailgun is complicated
Mailgun was built for complex enterprise setups with dedicated operations teams. The dashboard is confusing, the documentation is dense, and configuring a single domain can take an hour of DNS wrangling.
Missing modern tooling
If you want to use React to build your emails, you are on your own. Mailgun expects you to upload raw HTML or use their basic drag-and-drop editor. Sendbound natively understands React Email.
Expensive entry point
Mailgun removed their generous free tier. Sendbound gives you 3,000 emails per month for free, forever. You can build your MVP without paying a cent.
Support takes days
Unless you're on a premium support plan, getting help from Mailgun can take days. Sendbound provides direct Slack channels for Business customers and responsive email support for everyone.

Move from Mailgun in four steps
Avg time: < 1 hourVerify your domain
Add your sending domain. We walk you through DNS, DKIM, and SPF and verify automatically.
Install the SDK
One command. TypeScript types and IntelliSense included out of the box.
Swap the API call
Change your import and key. The REST API is intentionally familiar.
Go live
We monitor your first send live and stay on call. Lists, webhooks, and templates come with you.
Developers who made the switch
We were paying Mailgun $120/mo and struggling to get our templates to render correctly. We switched to Sendbound, write our templates in React, and pay $19/mo. It's a no-brainer.
The Sendbound API is so much cleaner than Mailgun's. The TypeScript types actually match the API response, which saved us hours of debugging.
