Enable/ Disable Outbox

Outbox helps you to delay the email, for a pre-defined duration, even after you hit the 'Send' button. The delay duration can be set from 1 minute to 120 minutes, based on the users choice. All the emails you send can be edited from the Outbox, or even deleted without sending, in case you change your mind.

You can enable Outbox which is an alternate way to 'Undo Send' after you hit the Send button. Even if Outbox is enabled, you can use the option ‘Send Right Now’ (Ctrl+Shift+Enter) under ‘Send’ to avoid the Outbox and send directly.

Steps to enable/ disable Outbox:

  1. Login to
  2. Click Settings icon >> Compose
  3. Locate Outbox and select your choice
    • Select send emails immediately if you want to send your emails without any delay
    • Select delay emails in Outbox for ___ minutes. Here you can set the number of minutes by which you want the email to be delayed.

If Outbox is enabled, the email will be moved to Outbox, once you click ‘Send’. It will be sent after the delay time specified or when you click ‘Send Right Now’ in Outbox.

All the mails in Outbox can be sent by selecting the emails, and choosing 'Send Right Now' from the top menubar. The emails that have been delayed will be sent to the recipients after the chosen delay period even if you are not online. Apart from the normal emails, even the Scheduled emails will be stored in the Outbox.
