What are my Seznam Email IMAP settings?

IMAP is imap.seznam.cz on port 993 (SSL); SMTP is smtp.seznam.cz on port 465. Auto-detected from your address.

Do email.cz and post.cz addresses work?

Yes. seznam.cz, email.cz, post.cz, stream.cz and spoluzaci.cz are all the same Seznam platform and use the same servers. Just enter your full address.

Does Seznam support calendar sync?

Yes. Seznam exposes CalDAV at caldav.seznam.cz, authenticated with your email address and password (or your Heslo pro aplikace with two-factor on), so anymailmcp.com can read and manage your events alongside your mail. Accept the Kalendář terms at kalendar.seznam.cz once first.

Before you connect

What you need

Your Seznam password

Use your full address including the domain (for example jan@seznam.cz) and your normal Seznam password. No IMAP toggle is needed.

With two-factor on: a password for apps

With dvoufázové ověření enabled, Seznam refuses your login password in mail programs. At ucet.seznam.cz open Zabezpečení účtu, then in the Dvoufázové ověření section set “Heslo pro aplikace”, and paste it here. The same password also opens the calendar.

Seznam Email works best with a revocable app password.

Under the hood

Server settings we auto-fill

You never type these. We detect them from your address and verify them live against Seznam’s servers — they’re here for the curious.

Server settings

IMAP: imap.seznam.cz:993
SMTP: smtp.seznam.cz:465
Encryption: SSL/TLS

Calendar: yes

Seznam calendar syncs over CalDAV at caldav.seznam.cz with your address and the same password as IMAP, including the Heslo pro aplikace with two-factor on. Before the first sync, open kalendar.seznam.cz once and accept the Kalendář terms, or the calendar login fails.
