What it does
Refine by Moosend is a tool that predicts the open rate of your subject lines and automatically suggest improvements! It uses artificial intelligence and a huge amount of past campaigns to produce data-driven results.
Test your subject line for free and receive an estimate for its open rate performance, as well as instant recommendations to improve it.
Get free, concrete subject line suggestions by our ever-advancing algorithm; it is learning every second, through thousands of campaigns at a time! Our foolproof drag-and-drop editor empowers you to confidently create gorgeous newsletters that will look great on any device. No need to be Picasso, here! Grow your open rate with an emoji! You can go for any emoji that semantically matches you subject line. Alternatively, for your industry, we suggest using this: You know, all the Joes and Janes in your list would really like that! Tamara’s and Blue Ivy’s would love the personalisation more! It’s one thing to see a hard-selling mass subject line and another to see your name carved there! Know…from moosend.com
