Posted on (0 Comments)

Earlier this spring, we shared 5 resources that can help you keep track of your sending reputation. Another good way to keep a check on your reputation is to find out if you are on any blacklists (a.k.a. blocklists). Blacklists contain lists of IPs or domains that pose a threat to consumer inboxes.

Posted on (0 Comments)

To close out our final section, metrics, in our 12 Days of Holiday Sending series, I want to re-emphasize a point that Kate made around testing in our ninth day of sending. “Your subscribers matter, and learning what they respond to best is just one way to show them you care.” In order to show your subscribers that you care, and in order to optimize your emails as best as possible, you need to make testing your emails a part of your daily practice.
