Enable Communication Limits - Marketo Docs - Product Docs is to prevent leads from getting more than X emails per day or 7 days. This applies to any Send Email campaign or program, including Engagements.
The smart campaign limit is for Campaigns only and is intended to block both emails and data flows that might exceed a certain amount
if you are an Admin, you can override the limit.
Thanks, I see that I can override and adjust the limit in Smart Campaigns, but is there a way to do the same thing in Email Sends that utilize the email send program and not a Smart Campaign to send it? From the looks of it, it doesn't seem like there is a way, or am I missing something.
