After those few keystrokes of typing, you then click to start the near-instantaneous process. Before you can say A/B test, those new subject lines are there on the screen for you to consider, adapt, or, just maybe, use.

Simple. Fast. And surprisingly creative. Try the Stensul AI-powered Email Subject Line Generator to see for yourself. 

For those a little hesitant, it’s worth noting that AI hasn’t suddenly appeared. It only feels that way. AI was established as an academic discipline, and computer scientists gathered to discuss it in the 1950s.  It’s come to the fore now because of the massive explosion in Big Data, the parallel developments of lots and lots of data being produced, and the growth in computing power to sort through, analyze, and draw inferences from it. Your risk, if any, is limited. Go ahead, and try the Stensul Subject Line Generator. If you’d like to learn more about Stensul’s Email Creation Platform, download this eBook
