What are my IONOS IMAP settings?

Port 993 (SSL) for IMAP, 465 for SMTP, but the hostname depends on your account's market — imap.ionos.de for German accounts, imap.ionos.com for international ones, and so on. We detect the right one from your mailbox's mail server automatically.

Do I need an app password for IONOS?

No. IONOS uses your normal mailbox password for IMAP.

Does IONOS calendar work?

On Mail Basic and Mail Business plans that include CalDAV, yes. We discover it on connect; if your plan has no calendar, email still works.

Connect your IONOS email to Claude & ChatGPT

IONOS (1&1) mailboxes are standard IMAP. If you host your domain with IONOS, your inbox is locked out of every AI assistant's native connector, and anymailmcp.com opens it up.

Set it up in your AI

Pick your assistant, paste one URL, done

Open Settings → Connectors in Claude Desktop or claude.ai.
Click Add custom connector and paste the URL below.
Click Connect, then sign in with your email (we send you a magic link). You add your mailbox from your profile afterwards.

Under the hood

Server settings we auto-fill

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

Server settings

IMAP: imap.ionos.com:993
SMTP: smtp.ionos.com:465
Encryption: SSL/TLS

Calendar: depends on your plan

CalDAV is available on IONOS Mail Basic and Mail Business plans. If your plan includes it, we attach the calendar automatically on connect; entry-level plans without CalDAV still connect for email.
