    This is likely due to the 64k limit. I encountered a similar issue and resolved it by changing the delivery method to a modified timed, batch delivery method, which I call EDM sending. Sending 800 or more emails at once will add the mail server ip into the blacklist. https://mxtoolbox.com/blacklists.aspx

    I'd like to add a feature that allows users to schedule and send emails in fixed quantities when sending a large number of emails at once, thus streamlining the process.

    Can you please explain what the problem is?

    there are other ideas where people suggest that it should not be possible to send mails to a large number of recipients.
