Dynamic templates have streamlined student and parent email campaigns and build consistent engagement
The activity log is a little slower at times, but that is probably just nitpicking an issue. Overall, in general, there are not really very difficult pain points. There are certain issues sometimes when we are trying to handle a very big campaign; we might end up having a little bit less reputation in terms of bounces or spam reports that get detected when we send out the emails. Apart from that, there is not anything that would become a significant pain point. If you don't really have an advanced subscription for SendGrid, it might take a while for you to reach the customer support.
