Web.de is one of Germany’s largest free webmail providers, part of the United Internet group that also runs GMX and Ionos. To connect a Web.de account to Outlook, Thunderbird, Apple Mail, or a mobile client, you need to enable POP3/IMAP access in your webmail settings first, then apply the server addresses below.
Web.de disables third-party client access by default for new accounts. Sign in to web.de, open Einstellungen → POP3/IMAP, and check “POP3/IMAP-Zugriff erlauben”. Without this, mail clients receive Nemesis ESMTP or generic authentication errors. See related bounce guides: Nemesis ESMTP errors.
Quick Reference: Web.de Server Settings
Use the values below verbatim. Every protocol requires encryption; Web.de rejects plain-text connections.
| Protocol | Server | Port | Encryption | Authentication |
|---|---|---|---|---|
| SMTP (outgoing, most common) | smtp.web.de | 465 (SSL) or 587 (STARTTLS) | Required | Full email + password |
| IMAP (incoming, recommended) | imap.web.de | 993 | SSL/TLS | Full email + password |
| POP3 (incoming, single device) | pop3.web.de | 995 | SSL/TLS | Full email + password |
Web.de SMTP Settings (Sending Mail)
SMTP is the outbound protocol for mail clients, WordPress SMTP plugins, and any app that sends through your Web.de account. The server is smtp.web.de on port 465 with SSL or 587 with STARTTLS. Authentication is required; use your full user@web.de address and your Web.de password.
Web.de shares outbound infrastructure with GMX and Ionos (all United Internet). Free accounts have a modest daily sending cap; bulk sending will trigger rate limiting even with correct authentication. If sending fails with a Nemesis ESMTP rejection, IMAP/POP is still disabled in webmail; enable it as described in the alert above. Related bounce reference: Nemesis ESMTP errors.
Web.de IMAP Settings (Recommended for Reading)
IMAP keeps folder state synced across all your devices. The server is imap.web.de on port 993 with SSL/TLS. Use your full email as username and your Web.de password.
Web.de uses German folder labels internally (Gesendet for Sent, Papierkorb for Trash, Entwürfe for Drafts), but IMAP presents them with standard SPECIAL-USE attributes, so Outlook and Apple Mail map them correctly. Thunderbird sometimes assigns the wrong folder for Sent; if that happens, set it manually in Account Settings → Copies & Folders.
Web.de POP3 Settings (Single-Device Access)
POP3 downloads to one device with no server-side sync. The server is pop3.web.de on port 995 with SSL/TLS. Note the pop3 prefix; pop.web.de resolves but points to a legacy load balancer that no longer accepts new connections. Web.de keeps a server copy after POP3 download by default; enable “delete from server” only if you want messages purged.

About Web.de
web.deWeb.de launched in 1995 as one of the first German internet portals, initially operating as a search directory before adding free email services. Acquired by United Internet AG in 2005, Web.de became a sister brand to GMX under the same corporate ownership, sharing backend infrastructure while maintaining distinct consumer brands.
Web.de serves an estimated 32+ million active users almost exclusively in Germany, positioning itself as the more traditional and mainstream option compared to GMX's slightly more tech-forward branding. The service offers free 1 GB email storage with FreeMail Plus and Club paid tiers.
Web.de uses IMAP, POP3, and SMTP with SSL/TLS. Server endpoints are on imap.web.de, pop3.web.de, and smtp.web.de. Two-factor authentication is available for account security.
Timeline
- 1995Web.de launched as German internet portal
- 1997Free email service added
- 2005Acquired by United Internet AG
- 2010sBackend consolidated with GMX infrastructure
Web.de shares the same underlying mail infrastructure as GMX. Together the two services represent the largest German-owned consumer email operation, competing directly with T-Online (Deutsche Telekom). Web.de's user base skews older and more mainstream than GMX's.
Frequently Asked Questions
How do I recover a forgotten Web.de password?
Open web.de and use “Passwort vergessen?” on the login page. Web.de sends a reset link to the recovery address or phone number registered on the account. Once reset, update the new password in every mail client; the old password stops working immediately for SMTP, IMAP, and POP3.
Can I access Web.de on mobile without an app?
Yes, the Web.de webmail is responsive and works in any mobile browser. For push notifications and offline access, install the official Web.de Mail Basis app (iOS and Android) or configure the mailbox in the native Mail app using the IMAP settings above.
What is the storage limit on Web.de?
Free Web.de accounts include 1 GB of mailbox storage plus 2 GB of cloud storage. Web.de Club (paid) accounts raise the mailbox to 12 GB and Cloud to 25 GB. If you approach the limit, incoming mail is rejected; the Sent folder is usually the first to trim.
How do I set up email forwarding?
In Web.de webmail, open Einstellungen → E-Mail → Filter & Weiterleitung, click “Weiterleitung einrichten”, enter the destination address, and save. Web.de sends a verification message to the destination before forwarding activates. You can choose to keep or delete a copy on the Web.de server.
Any security tips specific to Web.de?
Turn on two-factor authentication in the Sicherheit section. Web.de supports app-based TOTP codes. Once 2FA is on, third-party mail clients may prompt again for authentication; that is expected. Review the Anmeldeverlauf (sign-in history) periodically for unfamiliar sessions and revoke them if needed.
About This Guide
The Web.de email settings on this page were last verified on July 23, 2026 against the provider’s official help documentation, publicly available postmaster resources, and independent user setup reports. Email server configurations rarely change once established, most providers issue major updates only every one to two years, typically tied to phasing out unencrypted protocols or migrating to new mail infrastructure. SMTPedia re-verifies these settings quarterly and after any announced changes from Web.de. If you find a discrepancy between what is documented here and what Web.de currently requires, please report it so we can update the reference.
