Scheduling a merge lets you write or set up your correspondence now and have Rex send it at a later date and time. This is handy for reminders, follow-ups or announcements you want to go out at a particular time, without having to remember to send them.
This article covers how to schedule a single mail merge and a bulk mail merge. For how to set up a bulk merge, see - Sending an Email/SMS/Letter to Multiple Contacts.
When you're sending a merge, you'll see a Schedule Send option in the dropdown next to the Send button.

Which Merges Can I Schedule?
You can schedule Email and SMS merges. Letters can't be scheduled, because they need to be printed and posted.
Please Note: To send SMS merges from Rex, you'll need to be signed up with one of the SMS providers Rex integrates with. For more on this, see - Local SMS & Service Integration.
