Our users say it better

Posteo was okay, but I found the interface a bit outdated. I switched to Atomic Mail, and I’m so glad I did. It’s more modern, way easier to use, and has multiple encryption options. If you’re looking for the best alternative to Posteo, this is it.

The biggest downside of Posteo for me was the limited storage. I kept hitting the 2GB limit too quickly. Atomic Mail, on the other hand, doesn’t restrict storage and still keeps my emails private. It’s the best alternative to Posteo for anyone who needs more space and security. And for free)

I was looking for a secure email provider like Posteo, but with a more modern interface and better features (ideally for free). Atomic Mail is exactly what I needed! The encryption options are fantastic, and I love that it's eco-friendly too. It's the best Posteo alternative I've found.

Secure & private email

Secure your communications with Atomic Mail. A powerful, private Posteo alternative

As the best Posteo alternative, Atomic Mail prioritizes your privacy with robust encryption methods. Choose from TLS, password encryption, encryption as a file, or our proprietary Atomic Encryption to safeguard your messages. Our zero-access policy means your data remains inaccessible even to us, ensuring true privacy. Sign up anonymously without sharing any personal details, and manage account recovery privately through a customizable seed phrase.

While Posteo focuses on security, its encryption methods fall short of true zero-access standards. Emails are protected during transit with TLS and stored encrypted on their servers, but if "crypto mail storage" isn’t activated, Posteo could access your emails under certain conditions. Their commitment to data minimization (no IP logging) adds value, though their encryption doesn’t match the privacy offered by Posteo competitors with advanced encryption solutions.

Advanced email features in a free plan

Get advanced email features without compromise, even on our free plan

Atomic Mail is a free Posteo alternative with no storage limits or compromises on security. Our free plan includes all essential security and encryption features, and up to 10 free aliases. Secure, private, and feature-rich, Atomic Mail is perfect for anyone seeking free email like Posteo, but with more security and value. Even as we expand features on paid plans, it will never compromise on privacy or security.

Posteo doesn’t offer a free plan – every account is paid. Even then, it comes with significant limitations: only 2 GB of storage and 2 email aliases. Additional storage and aliases require extra payment. In contrast, many free Posteo alternatives provide more value in their free plans than Posteo does in its paid tiers.

Eco-friendly email designed for users

A green email service that doesn’t compromise on usability

We crafted Atomic Mail with care for every detail, ensuring it’s both eco-friendly and user-centric. Our modern interface makes navigation effortless for everyone, providing a smooth experience at every touchpoint. Our data centers in Germany, powered by 100% green electricity (hydro and wind), ensure sustainability. Efficiency is optimized by analyzing energy consumption in real-time, and natural air cools our servers for up to 98% of the year. This combination of innovation and sustainability makes Atomic Mail the top choice among eco-friendly Posteo alternatives.

Posteo is committed to environmental sustainability, using renewable energy to power its servers and operations. While their focus on green energy aligns with eco-conscious values, their user experience falls short. Many users report an outdated interface, occasional lags, and issues with customer support, according to user reviews. Considering the paid nature of the service, these problems are a significant drawback, leaving room for better Posteo alternatives that combine sustainability with modern usability.
