Subject line testing

High performing subject lines are critical for your open rates. The only way to find out which subject lines will maximise your open rates, is to test them!

Split Line testing is an essential tactic that will force better open rates and therefore ROI. Send just a small percent of your emails out using unlimited Subject lines and then BrotherMailer will automatically send out the rest to the Subject line with the most opens.

You can use subject line split-testing with the BrotherMailer split-testing tool. This invaluable ‘open-rate booster’ will simultaneously test an unlimited number of different subject lines in a campaign.

How does it work?

BrotherMailer automatically searches out the line which is performing the best, and switches the rest of your email sends to that winning subject line.

This is how you we help you improve your response rates and ROI, with cumulative intelligence from each campaign.
