Staged Email Sends

The first batch is an experiment

A campaign sent all at once gives you no chance to react. A broken link, a wrong merge field or a subject that trips filters reaches everyone before you learn about it. Sending a few hundred first turns an irreversible action into a reversible one.

Order the first batch by recent activity. Your most engaged recipients give the cleanest read on whether the message lands in the inbox, and strong early engagement is also a positive signal for the rest of the send.

Make the batches remember each other

The common bug in staged sending is a script that selects recipients in a fixed order and takes the first N. Run it twice and the same people get the message twice, which produces complaints from exactly the audience you were most careful with.

Log every successful send and exclude those addresses on the next run. A batch job should be able to answer who it has already reached, or it will eventually reach them again.

Frequently Asked Questions

Why send email campaigns in batches?

A small first batch lets you catch a broken link or a filtering problem before it reaches the whole list, turning an irreversible send into a reversible one.

How do I stop batches overlapping?

Log every successful send and exclude those addresses from later runs. Selecting a fixed-order list and slicing the first N will re-send to the same people.
