Have you ever fired off an ill-considered email and then thought oops! the moment you hit Send? Or have you sent off an email intended to impress the recipient, realizing with horror, seconds too late, that you have misspelled their name? And the “Reply all” button has been a recipe for far too many disasters.
Whatever the reason, Undo Send is one of the most popular features(ventana nueva) requested by Proton Mail users. It is now automatically enabled for all our users in the mail.proton.me(ventana nueva) web app, and provides a variable length second window during which you can opt to cancel sending an email.
How to use Undo Send in Proton Mail
When you send an email, the email composer window will close and you will see a banner at the top of your screen which says “Message sent. Undo.”
If you click the Undo button within the specified time limit, the composer window will reopen and you can continue editing the draft email.
Undo Send is enabled by default with a 10-second timer . You can change the timer duration from 0 seconds (i.e., Undo Send disabled) to your preferred timer length by going to Settings → All settings → Messages and composing → Composing → Undo Send.
A core part of our mission is to design tools that are secure, protect your privacy, and are also easy to use. To that end, we hope Undo Send will make Proton Mail more convenient and useful for you, and we look forward to hearing your feedback on this and other features in the Proton Mail Version 4.0 beta.
