I recommend you stop feeding Google your data and exercise the option to move it, while they still offer it for free.$30/month.....no thanks! Gmail has some nice options like forwarding/moving your email to a different client like Outlook. I suspect with enough work, you could nearly achieve the same thing as this service does.
The date is a coincidence. Sadly, this "innovative" service exists and the app is only available for iOS (go figure):OK, I was about to post to ask if this was being marketed by Scientolo...(you know who). Geemail's bad UI might be the author's real problem here. Seriously, I was going to try to save the author from them self. Exclusivity sells to... uh, some people. $30/mo built on a "free" no-privacy service?
Then I saw poohbear's comment (good spot, BTW!). You got me. Well played, my friend, well played!
Happy belated April Fools!
PS. Get Mailbox.org, Posteo, or even Fastmail...
