Alright, but not the best.

Tutanota is a great provider, free from the terrors of Google and Microsoft.

Fundamentally, Tutanota is good, and the fact they run on renewable energy is also a bonus.

However, I prefer using ProtonMail, partly due to the nicer design. I also prefer that Proton can block trackers in emails whereas Tutanota can only block all remote connections, which can cause some issues.

Developer Response ,

Thanks for your feedback, particularly on the design. We plan to improve this further!

The future of truly secure emails has arrived…

I recently reached out to this fantastic email app’s developers with a question regarding using my iPhone’s facial ID with Tutanota. I did think it probably was possible but I needed help from the developers so I could hopefully start using it (when it is available I always activate facial ID to add an extra layer of protection to any app that may hold sensitive information). I was really pleased (and grateful) to receive a reply from Tutanota’s developers confirming facial ID can be used with their brilliant app. I’ll now set up facial ID as soon as possible. Thank you to the Tutanota email app developers for responding so rapidly to my request. I wouldn’t hesitate for one moment to highly recommend the Tutanota email app to anyone who really values their online activity (alongside Apple’s already excellent security built into iPhone the email security offered by the Tutanota email app is very much appreciated).

Developer Response ,

Thanks for your feedback. You can activate Face ID after storing your login credentials. Here is more info:

Great App and Website

I’ve been using this app for years. I switched from Protonmail due to app issues. Tutanota are always improving their services by adding extra features and when they release an update they don’t introduce crashes or other issues as is often the case with other apps. If you’re looking to have private emails that aren’t being processed by your email provider then I recommend this app.

Developer Response ,

Thank you! 🥰
