How To: Edit or Cancel a Send Later Email
Change your mind about that email you've scheudled to Send Later? No problem!
Since Streak saves your email as a draft until it needs to be sent later, simply go to the Drafts folder in Gmail and click on the message you'd like to edit. Edit the email as you normally would and save the draft. Streak will send the latest version of the draft at the time your email is scheduled to be sent.
Edit Send Later Date / Time
To change the time or date an email will be sent, go to your Drafts folder in Gmail and select the relevant message. From the compose view, simply click the Send Later icon and edit the time you'd like the email to be sent. When finished, click Save and the email will be scheduled for the new time you created.
Send Email Right Now
To send an email right now instead of the scheduled future time, just go to the Drafts folder in Gmail and select the relevant message. Next, hit the Send button and your email will be sent right away. It will not be sent again in the future.
Cancel Send Later
To stop an email from being sent in the future, go to your Drafts folder in Gmail and pick the relevant message. Next, click on the Send Later icon in the toolbar and select Cancel Send Later. This will prevent your draft from being sent in the future.
Note: Canceling your email from being sent later will do only that. It will not automatically discard the draft email. If you wish, you can do this manually afterwards.
