Sometimes your quota for Yet Another Mail Merge doesn't reset daily and you can send less than what was planned. You'll find answers in this article.
Why can't I use all the quota I'm allowed?
Your daily quota will decrease faster in some specific cases:
If you have multiple recipients per email, including people added as cc / bcc, all the emails will be taken into account. So you will send less than 50 emails (e.g. if you send your email to 15 recipients and add 2 person in cc, you will have only 5 emails left).
