How to undo send
You can stop a message from being sent. Front will hold your message for a selected amount of time before sending it. You can enable the undo send option on every type of channel. By default, undo send is enabled on email channels and disabled on all other channels (Twitter, SMS, etc).
Because team inbox settings can only be accessed by admins, the time they select will apply when any non-admin sends a message from that channel.
Users without admin permissions can still change this setting for their individual inbox.
Click the gear icon on the top right of Front and into the Company or Personal settings tab, depending on which space you are working with.
Click Inboxes in the left menu, and select the inbox containing the channel you'd like to edit.
Go to the Channels settings for the inbox, and expand the channel settings.
Scroll down to Undo send timing, and select the amount of time Front will hold your message before sending it.
Click Save to finish.
After the setting is enabled, you will be offered the option to cancel after you send each message by pressing Cancel.
After the status bar disappears, it is no longer possible to cancel the sending of that message.
Cori Morris sure! essentially, we have a use case where If certain criteria is met I actually want to prevent an email from being sent. For example. I have a rule that says if a message is sent from X mailbox and the contact is not associated with Y contact group then "STOP". It's at stop where I cannot actually prevent the email from going out. So obviously there are other ways to skin this cat but if the THAT section of the rule had the option to "Undo Send" then at least I would have prevented the email from going out. Does that help?
