When you send a Gator message to a Slack direct message (DM) or group direct message, you can optionally turn on early delivery for your message. This will instruct Gator to deliver it as soon as one of your recipients next comes online in Slack.
This feature can be helpful you send an important Gator message and you want to ensure your recipient sees it as soon as they log in to Slack, even if that's before 9:00 AM in their time zone. Alternatively, it can be useful when sending a Gator message to a recipient in a time zone a few hours later than your own, where you know your recipient will start their day soon but you aren't sure exactly when.
To turn on early delivery for a new Gator message, click the "..." menu in the confirmation text for your new message and choose "Change delivery time":
That will open the "Reschedule your message" window. Find the check box under the "Early delivery" section of the form and click it to enable early delivery for this message:
Note: If you don't see the "Early delivery" section, that means Gator can't deliver this message early. This is most likely because you're sending the message to a channel instead of a DM.
Finally, click "Save" and you'll see a confirmation message on the next screen which says that Gator will attempt to deliver this message early if any of your recipients come online before the message's scheduled delivery time. If you change your mind and want to disable early delivery for a message, just click "Change delivery time" again and uncheck the early delivery check box.
And that's it! Want to turn on early delivery for every Gator message you create? You can do that through a Gator beta feature.
