Send Later is a feature that allows you to schedule emails to be sent at a later date and time. It is available on all the Pro, Premium, and Enterprise plans on our Gmail product.
To set up a scheduled email, open up a compose window in Gmail and write your desired message as you normally would. Instead of sending, click the green ‘Later’ button at the bottom of the screen and choose the date that you’d like for your message to be sent.
Once you create your scheduled email, it will be saved to the Scheduled section of the Events Dashboard in Gmail. If you'd like to edit the date or time, you may do so from the Events Dashboard.
If you'd like to cancel the scheduled email, simply locate the message in the Scheduled section of the Events Dashboard in Gmail or through your Draft folder. From there, click on "unschedule" or modify the scheduled send time.
