-Sending a batch message can be a time taking task on user end, it may take time for you to arrange all the recipents list that you want to send as batch message and what if your batch message failed so instead of doing all the havy work again and again with MailMerge its now possible to resend your batch message using different service (mailgun, pepipost, sendgrid). MailMerge saves all of your sent batch messages so you can retry that batch message in future in case of some system failure or if there are so many failed or bounced emails, when you retry or resend batch message it handle the logic of sending that batch message only for failed recipients from last batch so you can retry that batch message as many times as you want until all the emails from that batch are sent successfully.
