New email notifications stop working after a while. I have to turn the apps notifications off and back on to get them working again. Notifications are still in 24h instead of 12h. The zoom capabilities are poor. I have to double tap to zoom but it barely zooms. This is a problem because QR codes or any scannable barcodes are to small to be scanned.

Thanks for your feedback. We will look into this as we continuously improve the app. The latest update gave you offline mode with the Android app, meaning you are now able to read your emails and calendar events even when offline! :)

Like the security and ability to encrypt, but I wish there were a way to tag as phishing or spam without having to open the email. Also, about 50% of the time I don't get emails with attachments from my friends, so I still have to use my old Google email account (& I hate Google). My privacy is important to me (I don't use Google or similar as a search engine, either). Tutanota is good, but far from perfect.

Thank you for rating our encrypted email and calendar app. Best use spam rules to blacklist emails/domains: https://tutanota.com/faq#spam 1. Note: No external content is loaded when you open an email so the spammer will not see that you did. 2. Could you please send an email to your friends first & they reply? Most likely they mistype your address.

Love your email services. However your phone app needs work. It freezes a lot. It keeps refreshing while typing causing typing errors. When deleting emails it doesn't respond and has to be restarted and deleted again. It doesn't update to show sent and recieved emails quickly. There is a lag. Still overall I think your email services are fantastic and the best for encrypted services. The app needs a little work.

Thanks for rating Tutanota the best encrypted email service! :) Please check whether this is related to the Samsung keyboard issue described here. A different keyboard should fix the issue! https://www.reddit.com/r/tutanota/comments/10nr6gj/android_client_v31065_still_broken/ Did this help?
