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 I send less emails that 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).
If you are including personalized attachments, your quota will be lower due to restrictions from Google side. Read this article for more details
Your quota is shared among all the other add-ons script. So if you are using other applications to send emails / attachments, this will also impact your quota.
