Mailgun

3. Good to know

Mailgun has been the workhorse email API for over a decade, sending billions of messages a month for companies that treat email as infrastructure. It layers useful extras on top of raw sending: inbound routing, address validation and detailed analytics. Connect your Mailgun account and Rocketeers deals with the part everyone gets wrong — domain and DNS configuration — so your transactional mail authenticates cleanly from day one.

#What you get with Mailgun

• A proven, high-volume email API for password resets, receipts and notifications.
• Sending domains created and verified for you, with SPF, DKIM and DMARC records set up correctly.
• US and EU sending regions, so you can keep mail data on the right side of the Atlantic.
• Logs, analytics and deliverability tooling in your Mailgun dashboard.
• No manual DNS spelunking — Rocketeers wires up the records for you.

#How the integration works

Add your Mailgun API key (found under API security in your account) and tell Rocketeers which domain should send mail for a site. Rocketeers registers the sending domain with Mailgun and publishes the DNS records that authentication requires — SPF, DKIM and DMARC — automatically where it also manages your DNS, or hands you the exact records to add if it doesn't. Once verified, your sites send through Mailgun with proper alignment.

#Good to know

• Choose the US or EU region when creating a domain; the two are separate environments with separate API endpoints, and domains don't move between them.
• Use a subdomain for sending (like mg.yourdomain.com) — it isolates your transactional reputation from your root domain.
• Mailgun's pricing is volume-based with a trial to start; heavy senders should look at plans with dedicated IPs.
• DMARC only passes when SPF or DKIM aligns with the From domain — the setup Rocketeers applies is built around exactly that.
