Pricing FAQ.
How is CeyMail different from Resend and Mailgun?+
Resend and Mailgun are transactional email APIs that route your outbound mail through their infrastructure and charge per email. CeyMail is the full mail server stack you install on your own VPS: SMTP, IMAP, DKIM, spam filtering, and a developer dashboard. You own the infrastructure, the IPs, and the sending reputation. You pay a flat license and never hit a per-email meter.
What does the install actually do?+
One curl command bootstraps Postfix, Dovecot, OpenDKIM, SpamAssassin, MariaDB, the CeyMail dashboard, and provisions Let's Encrypt certificates. It's idempotent: safe to re-run, and works on any Ubuntu 22.04+ or Debian 11+ VPS.
Will my email actually reach inboxes?+
CeyMail auto-generates the exact DKIM, SPF, DMARC, MTA-STS and TLSRPT records you need, and verifies each one from the dashboard. Deliverability also depends on your IP reputation. The dashboard includes blacklist monitoring and can route through Amazon SES, SendGrid or Mailgun as a relay when your IP is warming.
Can I use CeyMail as an SMTP API for my app?+
Yes. Point your app at the SMTP submission port (587) with a mailbox credential, or use the REST API on the Business plan to provision domains and users programmatically. Same interface Resend and Mailgun expose, hosted on your own hardware.
What happens to my mail server if I stop paying?+
Postfix and Dovecot keep running. Existing domains and mailboxes keep sending and receiving. The license downgrades to Community, so paid features (AI screening, DKIM management, queue monitoring, in-dashboard updates) become unavailable, but nothing is deleted or shut off.
Do I need Linux experience?+
Not for day-to-day operations. The dashboard handles domains, users, aliases, DKIM keys and mail queues. You'll need SSH for the initial install and periodic OS patching: that's it.
