One of the best free email service.

I love the email service but I the ui of the app feels kinda slow.

Developer Response ,

Thanks for your feedback. Have you activated offline mode? This will make loading of the app much faster:

They resettled my account

It’s a good service no doubts, but when I didn’t open my email for 6months, they without any notice deleted my all emails and made me start fresh.
So don’t use this mailing service as a 2nd alternative, use it as your main and check on time to time if you don’t want to come back and see everything deleted.

Developer Response ,

Thanks for rating our secure email & calendar app. We're sorry that you had this experience, please make sure to login regularly and you can keep using the free version forever!
