I’ve used Tuta for years, paid account with multiple custom domains.
I prefer them for their principles, but their clients are extremely frustrating. Emails load very slowly and their email search is basically unusable.
I’ve resorted to downloading old emails and using other clients to import and search through them. I really wish they would improve their email search.











I should re-iterate I download the emails to use in an offline client. Their service doesn’t support third party clients to receive and send email.
When I do taxes, I need to search thousands of emails for receipts and the tuta apps make this impossible. This is my workaround.
