1 and 1 Webmail (Ionos): our 2026 review of the professional email service

Our 2026 review of Ionos webmail (formerly 1&1): pricing, AI, security, alternatives. Rating 4/5 and our recommendations based on your profile.

1 and 1 Webmail, now marketed under the brand Ionos, remains one of the most widely used professional email solutions among French-speaking freelancers and SMEs. At €1.20 excl. VAT per month as an entry-level offer, the service appeals with its price and its European roots, but users coming from Gmail or Microsoft 365 naturally ask the question: does the quality measure up? After several weeks of testing the two main plans (Mail Basic and Mail Business), here is our full review for 2026, pros, cons, and a data-based comparison with the competition.

Quick verdict: should you choose 1 and 1 Webmail (Ionos) in 2026?

Overall rating: 4 / 5 Ionos Webmail is an excellent choice for freelancers, very small businesses, and SMEs with up to 50 people who are looking for reliable, GDPR-compliant and affordable professional email. It is particularly suitable for clients who already host their website with Ionos. On the other hand, it is less relevant for highly collaborative teams (Google Workspace or Microsoft 365 remain more powerful) and for privacy-conscious users (ProtonMail offers native end-to-end encryption).

1 and 1 Webmail / Ionos: what you need to know

The brand 1&1 became Ionos in 2019, as part of the rebranding of the German group United Internet. In 2026, “1 and 1 Webmail” remains the term most often typed into Google by former customers, but the interface, billing, and official documentation now use only the name Ionos. The webmail access URL is mail.ionos.fr (or mail.ionos.com depending on the country). A few figures to put the publisher in context:

• More than 8 million customers worldwide
• Data centers in Germany, ISO/IEC 27001:2013 certified
• Native GDPR compliance (servers EU, strict German law)
• Recommended by AFNIC in its “Je passe au numérique” initiative for craftspeople and small retailers

Plans and pricing in 2026

Ionos mainly markets two formulas for pure email, plus hosting + email packages for websites. Here are the prices observed in May 2026:

Important to know : like almost all hosting providers, the Ionos prices shown are introductory prices valid for the first year. Upon renewal, expect to pay 2 to 4 times more. With a 36-month commitment, the average price nevertheless remains competitive.

Features tested

Webmail interface: clean and functional

The interface accessible on mail.ionos.fr is stripped down, ad-free, with native sorting (inbox, important, drafts, sent, archives). It is responsive and works correctly on mobile via the browser. Compared with Gmail or the new Outlook web, it looks a bit dated, but it has the advantage of speed and readability. No unnecessary animation, no pop-ups, no marketing nudges.

IMAP, POP3 and SMTP synchronization

All standard protocols are supported. Configuration tested and validated with:

• Microsoft Outlook (Windows and macOS)
• Apple Mail (macOS and iOS)
• Mozilla Thunderbird
• Native Mail iOS and Gmail Android apps

Server settings: IMAP imap.ionos.fr port 993, SMTP smtp.ionos.fr port 465 or 587, automatic SSL/TLS encryption.

Security and GDPR compliance

This is Ionos’s real strong point in 2026. All mailboxes are:

• Hosted in Germany in ISO 27001-certified and geo-redundant data centers
• Automatically encrypted with SSL/TLS in transit
• Filtered by integrated anti-spam and antivirus protection
• Backed up daily with a 7-day recovery window after deletion
• Compatible with two-factor authentication (2FA)

Please note: Ionos does not offer end-to-end encryption (E2E) like ProtonMail or Tutanota. For the majority of SMEs this is not a problem, but it is a drawback for lawyers, journalists, or doctors handling highly sensitive data.

AI email assistant (new for 2026)

Ionos has optionally rolled out an AI-based email assistant, capable of:

• Writing a draft from a few keywords
• Reformulating or shortening an existing email
• Automatically translating between several languages
• Summarizing a long discussion thread

Available as a paid option at checkout, with a monthly quota. Performance is decent for standard uses, though still light-years behind Copilot in Microsoft 365 or Gemini in Google Workspace in terms of integration depth. If AI is a majorr factor for you, do not choose Ionos for this feature alone.

Migration tool from another provider

Ionos provides an integrated migration tool that transfers contacts, emails, and folders from any IMAP provider. Tested from Gmail and OVH: operation completed without data loss on mailboxes of several GB. It is a real advantage for anyone who wants to switch painlessly.

Comparison with competitors in 2026

Ionos’s positioning is clear: a compromise between low prices, European GDPR compliance, and comprehensive professional services. On pure pricing, OVHcloud beats it very slightly. For collaboration, Google and Microsoft dominate everything. For absolute privacy, ProtonMail remains ahead.

The real advantages of 1 and 1 Webmail (Ionos)

• Unbeatable entry-level price for a European solution (€1.20/month on promotion)
• Native GDPR compliance with German data centers certified ISO 27001
• No advertising in the webmail, unlike free consumer solutions
• Email recovery up to 7 days after deletion
• Migration tool built in that simplifies switching from Gmail, OVH, etc.
• Synergy with Ionos hosting : if you already have a site with them, adding a mailbox sometimes costs less than €2 per month
• 24/7 support in French, reachable by phone and chat
• Official recommendation from AFNIC for craftspeople and small retailers

The real limitations of the service

An honest review must say it:

• Promotional pricing for the first year only. Renewal at €4 (Basic) or €7 (Business) remains correct but still always surprises new customers.
• Mail Basic storage limited to 2 GB. Insufficient for anyone who receives a lot of attachments or archives for a long time.
• Less modern interface than Gmail or the new Outlook web. Functional, but without the polish of American competitors.
• No native end-to-end encryption. For privacy-focused profiles (lawyers, doctors, journalists), ProtonMail or Tutanota remain preferable.
• Limited collaborative ecosystem. No equivalent to Google Docs or Teams. For a team of more than 10 people doing intensive collaboration, Microsoft 365 or Google Workspace quickly make up for their extra cost.
• AI assistant lagging behind. Correct for basic tasks, far behind Copilot and Gemini in deep integration.
• Support procedures sometimes lengthy on advanced technical issues (DNS, MX, SPF/DKIM/DMARC configuration) according to user feedback.

Who is 1 and 1 Webmail (Ionos) for?

✅ You should choose Ionos if:

• You are a freelancer, craftsperson, or small business and are looking for a professional address for less than €5/month
• You already host your website with Ionos (pricing and administrative synergy)
• GDPR compliance with European hosting is non-negotiable for your clients
• You want a solution without advertising or resale of behavioral data
• You are migrating from a free mailbox (Gmail, Yahoo, Free) and want a truly professional image

❌ You should look elsewhere if:

• Your team collabore intensively (video meetings, shared docs, drive) → Google Workspace or M365
• You handle ultra-sensitive data (lawyer, doctor, journalist) → ProtonMail or Tutanota
• You are extremely price-sensitive on the unit cost and 1 GB difference matters little to you → OVH or Zoho
• Generative AI in messaging is central for you → Microsoft 365 + Copilot

FAQ — 1 and 1 Webmail (Ionos)

Does 1 and 1 Webmail still exist in 2026?

Yes. The service still exists but under the name Ionos since 2019. Technical and commercial continuity is total: former 1&1 customers have kept their addresses, their mailboxes, and their settings.

What is the URL to log in to Ionos webmail?

mail.ionos.fr for France, mail.ionos.com for the international version. The username is the full email address, and the password is the one set when the account was created.

What is the difference between Mail Basic and Mail Business at Ionos?

Mail Basic offers 2 GB per mailbox and is suitable for moderate individual use. Mail Business goes up to 50 GB per mailbox and includes MobileSync (calendar, contact, and task synchronization across all devices, equivalent to ActiveSync), making it a true team solution.

Is Ionos more secure than Gmail or Outlook?

In terms of GDPR compliance and European data location, yes. For anti-spam filtering and resilience against attacks, Gmail remains slightly superior thanks to the volume of data processed by Google. For absolute privacy, ProtonMail surpasses all three.

How do I migrate my Gmail emails to Ionos?

Ionos provides an integrated migration tool that automatically copies contacts, emails, and folders from any IMAP provider, including Gmail. Allow a few hours for a mailbox of several gigabytes, with no tested data loss.

Does Ionos webmail offer artificial intelligence?

Yes since 2024-2026, as a paid option. The AI assistant helps write, reformulate, translate, and summarize emails. Decent performance for standard uses, but lagging behind Copilot (Microsoft 365) or Gemini (Google Workspace).

Do Ionos prices increase after the first year?

Yes, as with most hosting providers. The introductory rate of €1.20/month generally goes up to €4/month upon renewal for Mail Basic. This is specified in small print at the time of ordering, but it should be anticipated in the budget.

Can Ionos be used with Microsoft Outlook?

Yes, without difficulty, via the standard IMAP and SMTP protocols. The settings are automatically recognized by recent versions of Outlook. For Mail Business, MobileSync enables Exchange-type synchronization (calendar, contacts, tasks in addition to emails).

Conclusion

1 and 1 Webmail / Ionos is not the flashiest email service on the market, but it is probably the best quality-price-GDPR compromise for a French-speaking freelancer or SME. At €1.20 for the first year then €4 upon renewal, you get a professional mailbox without ads, hosted in Germany, with 24/7 support. For those who simply want to send and receive emails seriously, without depending on the American giants, it is a pragmatic choice. For those seeking a complete collaborative ecosystem or absolute encryption, it is better to look elsewhere. Our final rating: 4 / 5
