One of the sales reps at my company is trying to send an email to her client list using Zoho's Mail Merge widget. The staff member in question is using a Mail Lite account. When she sent the mail merge, according to the Merge History menu, the merge sent 50 emails out and then stopped sending out new ones, leaving a significant backlog.

I understand (now) that there's a 250-email limit on outgoing mail merges for Mail Lite accounts. I also understand that there's a 50-email outgoing limit on Zoho Mail accounts to prevent people from sending out spam email blasts, and I find this to be a sensible limit. I assume that the limit refreshes every hour, although I haven't been able to find that setting in the Mail Admin Console.

However, given that the explicit reason for using Mail Merge is to send up to 250 personalised emails in a short time using a single template, why do outgoing mail merge emails count against the 50-email outgoing limit? Why are both limits being applied, rather than only one or the other? 

I'd also like to know where the limits for outgoing emails can be managed in the Mail Admin Console, as the Help page "Outgoing Rules for Emails" (https://www.zoho.com/mail/help/adminconsole/outgoing-rules.html) seems to be outdated, as it's referring to a Security & Compliance menu that no longer exists in the Console.
