What is the latest verified information about 1 and 1 webmail?
Current service status
- 1&1 webmail is actively operated by IONOS SE. All email functions remain available via login.ionos.com (IONOS Help – service status).
- The official mobile application is still named “1&1 Mail” and can be downloaded from both major app stores (Google Play listing).
Rebranding to IONOS
- In 2018, 1&1 Internet merged its hosting and email products under the IONOS brand (Wikipedia – IONOS history).
- Existing users did not lose any email data during the transition (IONOS email settings overview).
Available features
- Supports IMAP, POP3, and SMTP with full SSL/TLS encryption (IONOS Help – incoming mail server).
- Two-factor authentication is available for account security (IONOS Help – two-factor authentication).
Long-time 1&1 users face a one-time URL change. Your mailbox content, password, and filters carry over — but if you try to log in at the old 1and1.com address, you’ll be redirected. The catch: some third-party email clients need explicit server updates.
The implication: users can rely on the current settings and should expect continued service.
What should readers know first about 1 and 1 webmail?
Service overview
- Originally part of 1&1 Internet (founded 1988), 1&1 Webmail provided free and paid email accounts for personal and business use (Wikipedia – 1&1 Internet).
- Today, all new subscriptions are sold as IONOS Mail, but legacy users retain their existing accounts (IONOS email settings).
Key facts
- Login is centralized at login.ionos.com — the same portal used for IONOS hosting, domains, and cloud services (IONOS Identity Portal).
- No data loss, no forced migration: existing 1&1 mailboxes work exactly as before (IONOS Help – Apple Mail setup).
The implication: if you’ve been ignoring the IONOS rebranding, you can keep using your old setup — as long as you know which login page to type.
Which official sources confirm key claims about 1 and 1 webmail?
Official IONOS login page
- login.ionos.com is the primary authentication portal for all IONOS services, including email (IONOS Help – login overview).
- id.ionos.com provides product-specific logins (e.g., email, hosting).
Help center documentation
- help.ionos.com contains step‑by‑step guides for email client configuration (Office 2016 Outlook setup).
- Protocol‑specific pages confirm IMAP, POP3, and SMTP server addresses and ports.
Mobile app store listings
- The Google Play Store listing for “1&1 Mail” is maintained by IONOS SE (Google Play – 1&1 Mail).
- The Apple App Store version is also official (App Store – 1&1 Mail).
The pattern: three authoritative layers — the login portal (operational), the help center (instructional), and the stores (distribution) — all carry the IONOS SE name.
What is still unclear or unverified about 1 and 1 webmail?
Migration timeline
- IONOS has not published a specific date when all legacy 1&1 login URLs (e.g., webmail.1and1.com) will be fully redirected or decommissioned (IONOS Help Center). The current redirect is operational, but the sunset plan remains internal.
- Whether legacy server names (imap.1and1.com) will continue to work indefinitely
Feature parity
- Whether every legacy feature — such as the original spam filter rules or custom mailbox folder structures — transfers identically to IONOS Mail is unverified (IONOS email settings overview).
- Whether advanced spam filter settings are fully replicated
Legacy interface availability
- The long‑term plan for the mobile app name “1&1 Mail” is still unclear. IONOS may rebrand it to “IONOS Mail” in the future (Google Play listing).
Users who rely on the old web interface should bookmark login.ionos.com now. If a future feature gap appears — say, missing filter types — you’ll need to adjust based on IONOS Mail’s feature set, not the original 1&1 one.
The pattern: the most significant unknowns revolve around timing and feature equivalence, not core service availability.
What are the most common user questions on 1 and 1 webmail?
Login issues
- “Why can’t I log in at the old 1and1.com address?” — The server now redirects to IONOS. Use login.ionos.com instead (IONOS account login help).
- “Forgot password.” — Reset via the IONOS account portal at login.ionos.com/password/forgotten.
Client setup (Outlook, Apple Mail, mobile)
- IMAP settings are the single most requested technical detail (Mailbird setup guide for 1and1.com).
- Outlook users must check “My outgoing server (SMTP) requires authentication” (IONOS Outlook 2016 setup).
Account recovery
- If you lose access to your email, IONOS help documents two‑step verification reset and backup email addition (IONOS two‑factor help).
The catch: most common issues stem from one root cause — users trying the old URL or using outdated server names (e.g., imap.1and1.com vs. imap.ionos.com).
The table below lists all supported server configurations for email clients.
| Protocol | Server | Port | Encryption | Username |
|---|---|---|---|---|
| IMAP | imap.ionos.com | 993 | SSL/TLS | Full email address |
| POP3 | pop3.ionos.com | 995 | SSL/TLS | Full email address |
| SMTP | smtp.ionos.com | 465 | SSL/TLS | Full email address |
| SMTP (alternative) | smtp.ionos.com | 587 | STARTTLS | Full email address |
| Legacy IMAP | imap.1and1.com (still works) | 993 | SSL/TLS | Full email address |
| Legacy POP3 | pop3.1and1.com | 995 | SSL/TLS | Full email address |
| Legacy SMTP | smtp.1and1.com | 587 | STARTTLS | Full email address |
Six server options, one pattern: the current IONOS names (imap.ionos.com, smtp.ionos.com) are the recommended targets. The old 1and1.com equivalents still accept connections, but IONOS may eventually retire them.
How to log in and set up your 1&1 webmail (step by step)
Step 1: Log in via the web browser
- Open login.ionos.com in any modern browser.
- Enter your complete 1&1 email address (e.g., you@yourdomain.com) and your current password.
- Click Log in. You’ll be taken to the IONOS Mail dashboard where you can read and send messages.
Step 2: Set up your email client (Outlook, Apple Mail, etc.)
IONOS recommends IMAP as the default account type (IONOS Apple Mail setup). Use these settings:
- Incoming mail server (IMAP): imap.ionos.com, port 993, SSL/TLS
- Incoming mail server (POP3): pop3.ionos.com, port 995, SSL/TLS (if you prefer POP3)
- Outgoing mail server (SMTP): smtp.ionos.com, port 465 (SSL/TLS) or port 587 (STARTTLS)
- Username: your full email address
- Authentication: include SMTP authentication; in Outlook, check “My outgoing server (SMTP) requires authentication” (IONOS Outlook 2016 guide).
Step 3: Reset your password if you’ve forgotten it
- Go to login.ionos.com/password/forgotten.
- Enter your email address and click Send reset link.
- Check your alternative email or phone for a verification code. Follow the link to set a new password.
Step 4: Download the mobile app
- Android: Install “1&1 Mail” from Google Play (Google Play – 1&1 Mail).
- iPhone/iPad: Install “1&1 Mail” from the App Store (App Store – 1&1 Mail).
- After installation, log in with your email address and current password. The app automatically configures server settings.
The consequence: following these steps ensures access regardless of platform or client.

“When setting up an IONOS email account in Apple Mail, IMAP is the recommended account type for best performance.”
IONOS Help – Apple Mail Setup
“For 1and1.com IMAP, use server imap.1and1.com, port 993, SSL. For SMTP, use server smtp.1and1.com, port 587, STARTTLS.”
Mailbird Setup Guide for 1and1.com
For anyone still using a 1&1 email address, the choice is simple: update your bookmark to login.ionos.com and, if you use a desktop client, switch the incoming/outgoing server names from imap.1and1.com to imap.ionos.com (and smtp.1and1.com to smtp.ionos.com). The consequence if you don’t: eventually your client will fail to connect when the legacy servers go offline. German and international users alike — IONOS Mail is your single access point now.
