Throttling TXNewsletters with Cron and Send Limits

the original question was operational rather than editorial: how do you stop a newsletter tool from sending too many emails per hour on a host with strict limits?

Good Direction

• Break delivery into batches.
• Trigger sending through cron or another scheduled process.
• Track progress so the next batch starts where the previous one stopped.

Whether the package supports the full logic out of the box or needs a small wrapper, the architecture should be the same: newsletters are jobs, not one-page actions.
