Analytics and reporting: Once you send an email, you'll want to determine how it's doing. Most services provide a range of data, including how many emails you sent, how many of them landed in inboxes, the bounce rate, who opened your emails, and the number of clicks and opens by location. Click-through rate and open rate are two basic metrics all email marketing services should provide. Those are important metrics to track for businesses.
