Escape Mailgun's per-email pricing

Mailgun invented the developer email API: and monetized every message you send. CeyMail gives you the same SMTP + REST + inbound routing on a VPS you control, at a flat monthly cost regardless of volume.

What you pay per year.

Switching takes an afternoon.

  1. 1

    Point your app at the SMTP submission port (587) with a mailbox credential. Same port, same protocol.

  2. 2

    Update DNS per domain. CeyMail auto-generates and verifies SPF, DKIM, and DMARC records from the dashboard.

  3. 3

    Replace the SDK import. CeyMail uses identical method signatures to the API you are already on.

Questions about moving from Mailgun.

Is Mailgun cheaper for very low volume?+

At tiny volumes (a few thousand emails per month) Mailgun's free tier and low-volume pricing wins on absolute cost. CeyMail wins when you want full mailboxes, no per-email meter, or predictable pricing at scale.

Can I still use Mailgun as a relay in front of CeyMail?+

Yes. CeyMail's SMTP relay integration works with Mailgun, SendGrid, Amazon SES, Postmark and any custom SMTP. Use it as an IP warm-up strategy or a failover path.
