We have a large database, and we need to throttle the amount of emails sent during a particular timeframe (e.g., 24 hours) so they are not delivered all at the same time. We also need the ability to define the number of emails a particular contact receives during a specific time period (e.g., 1 email per day, 3 emails per week, 5 emails per quarter, etc.).
We running into servers blocking our emails because we are sending too many at once, and we are also experiencing issues with particular contacts receiving far too many emails because the qualify for too many campaigns.
These are standard features of most email service provider platforms. We need them here, too!
