High performing subject lines are critical for your open rates.
There's only one sure-fire way to find out which subject lines will maximise your open rates – and that's through testing.
So we include an ingenious split-testing tool in dotMailer.
Use this invaluable ‘open-rate booster’ to simultaneously test an unlimited number of different subject lines in a campaign.
dotMailer will automatically analyse which line is performing the best, and switch the rest of your email sends to that winning subject line.
This is how you we help you improve your response rates and ROI, more and more each with each campaign.
