I would like to see an "Undo Send" feature, as found in Gmail. This is essentially a delay in sending, I guess, during which you can click an "Undo" link that appears in the bottom of the screen after you have hit "Send" on an email, for a varying amount of time that you can set (ex. 20 seconds). This gives you the chance to abort the send and tweak the message if, after hitting send, you realized you had forgotten something or you wanted to change the tone. It's something I find I use quite often for work.
I think 20 seconds is too short for realize that we made a mistake
I vote for this feature too, loudly :)
William Porter, I think that fulltext search is against the proclamation, that event protonmail itself is not able to read the deciphered content of the users, and as the ciphers and hashes work for the text as a whole, not just the simple words, it is not possible to search. Not to mention the advanced search techniques considering the mistypes and parts of the words.
This would be very useful. I often send an email but immediately think of something I want to change or a reason to wait before sending, so an undo send feature for 30 seconds would be helpful.
I just sent a half completed email by accident, googled "undo send protonmail", and here I am.
I also feel that this is a really really really useful feature. Please consider implementing sooner rather than later, if at all possible.
(Also, as already mentioned by other users, "scheduled send" features would also be very desirable. But this is a bit of a different thing than "unsend").
I guess the title speaks for itself and it is in urgent need. The undo option can last for 30 seconds.
Please, PM. Implement it immediately. I don't this needs voting. It has become a basic features now in widely used FREE email platform and we're paying customers and to do without these features feels very disabling.

I'd really like to switch my work email to ProtonMail from Google's G Suite, but Google provides three features that I don't think I can live without in ProtonMail. Undo Send is #1. #2 is scheduled send (fairly new to G Suite but very useful) and the last is full-text search of emails. TutaNota provides full-text searching and I like it's UI as well, but in nearly all other respects it's not nearly as mature a product as ProtonMail, so I don't see TutaNota as an option.
If ProtonMail just added Undo Send (a.k.a. "send delay") I'd be strongly tempted to use it exclusively.
Totally for this idea! As a business user, there are times when you have to redo the content of the email before sending. Every word is crucial so you really have to think about what you are saying and this Gmail feature saves a lot. Would like to see this in Protonmail because I'm leaning more and more to using the platform for my businesses, but the features are still lacking.
