Question 1

Proton is privacy-focused — isn’t it more private than CeyMail?

Accepted Answer

Proton encrypts your email on their servers, but your data still resides on Proton’s infrastructure in Switzerland. With CeyMail, email never leaves your server at all. You choose the jurisdiction, control physical access, and decide encryption policies. For organizations where data sovereignty is non-negotiable, self-hosting is the most private option.

Question 2

Does CeyMail support end-to-end encryption?

Accepted Answer

CeyMail uses standard TLS encryption for email in transit and you can enable full disk encryption on your server. For end-to-end encryption between specific parties, users can use PGP/GPG with any email client connected to CeyMail.

Question 3

Can I use Outlook or Apple Mail with CeyMail?

Accepted Answer

Yes. CeyMail uses standard IMAP and SMTP, so it works with every email client out of the box. Proton requires their Bridge app for third-party clients, which adds complexity and a point of failure.

Question 4

Why choose CeyMail over Proton for a team?

Accepted Answer

Cost and control. CeyMail’s flat-rate licensing saves 80% vs. Proton for a 50-person team. You get AI spam screening, AI log analysis, and outbound screening that Proton doesn’t offer. And your data stays on infrastructure you control, not a third party’s.
