If you exceed the emailing limits when emailing multiple/ bulk clients, a warning message will appear.
The emailing limits in Client Management are as follows:
Up to 10 emails per recipient every 24 hours
Up to 500 clients at once
Up to 1000 emails in total every 24 hours
Up to 100 "send me a copy" emails to an accountant every 24 hours
Up to 10,000 emails in total per month
NOTE:
The 10-email limit applies to an email address, not an individual client. If several clients share an email address, emails sent to any of them count towards the same limit.
