hmmmm you might be able to cook something up on IFTTT + Gmail 

Alternatively you have rebump...which would do it but not let you do time selection..
Sorry these are two different things, I still have the top one... it's from the options to schedule messages without sending a new one...
HEy Mate, 
Looks like they updated the app and didn't tell anyone, this is how my one looks like now , You are right we are talking of the same thing... Must have updated in the last day or two..

I think we might be talking about different things here, all your options are completely different too..

Mine's a Chrome plugin for Gmail ? is yours the same?
Alex,
This is the only reason I even bother to post an idea or comment here for MX, you guys actually listen,
Appreciate your work.
Thanks,
Hey Johan, You could leave some votes for this idea, so this could get higher priority. :-)
You can still use the Undo in 5 secs feature, I use it all the time with MX hero no problem
This is a must have, Infact go one step further and archive the email when it is scheduled.
Especially when you think of it, by scheduling an email to return after a certain time , we have finidhed acting on it for the time being.

So ideally it should be archived so we can go to the next email,  I use 'e' to archive it but logically it should automatically do that like Boomerang does.
Also can you please advise how do I find all the emails that have been scheduled?
This wasn't covered in the tutorial, and you guys don't have a new label added to the mail.

I know I can search by noreply@mxhero but that isn't the best way, i'd think.
Yes Like 'e' for archive, have another shortcut for snooze for 7 days, or have a different shortcut like ctrl+m and then 1 goes to the first time setting,
ctrl+m and then 2 goes to the second time setting, and so on.
