Subject Line Tester: Score Email Subject Lines
Subject Line Tester is an email subject line tester that scores each line for length, spam words and the phone cut-off and shows it in an inbox preview. It replaces guessing and picking lines by feel. Signed in, you log every send with opens and clicks and see which patterns win, with a ranked list of the winners. Made for a growth lead at a small startup who sends a few emails a week. Clone it free and start with sample data.
