Mailbox service that once bought Dropbox closes on February 26

For those who have not used: Mailbox is an email client for iOS, Android, OSX, Windows. He only integrated with Gmail.

The main difference from regular mail clients is the use of the 'Inbox Zero' principle, which turns the inbox into a to-do list and suggests striving to keep it empty.



To clean incoming messages, you could swipe right or left; these gestures later appeared in other email clients: Mail for iOS, inbox, etc. Nevertheless, I like the implementation of swipe the most in Mailbox.


Also, for me a very important point was the ability to postpone the letter / tasks for any period after which they again appeared in the inbox.

Actually, I would like to discuss some alternatives for this service.
I'd love to see the following things:

• client for iOS
• client for macOS
• the ability to postpone a letter for a certain period
• comfortable gestures
• Gmail sync
• the ability to work with Gmail and through the web

More detailed information can be found on the company's website .

Update: to summarize my research

1. First Place: Inbox
   
   • You can put off letters: snooze
   • It is possible to work from the desktop (via browser)
   • Gestures work in the mobile client
   • You can postpone a letter by geolocation tag. Arrived home, and received a reminder to call Gennady.
   • And all this is free
   
   
2. Second place: surprise! ... Outlook
   
   • You can put off letters: snooze
   • There is an opportunity to work from the desktop, which is probably known to everyone
   • Gestures work in the mobile client and it’s free.
   • In general, the quality of the mobile client is on top
   • The desktop client is very decent: 6320 ₽
   
   
   
3. There is no third place, because everything else did not fit my strict requirements
