When it comes to deciding how to craft that perfect subject line, there appears to be really only one area to avoid: the subject line of 60 to 70 characters. Marketers refer to this as the “dead zone” of subject length. According to research by Adestra, which tracked over 900 million emails for its report, there is no increase in either open rate or clickthroughs at this 60-to-70 character length of subject line.
"I’m predicting that in the Year 2020, that there will be an uptake in robust, hypothesis-led A/B testing. A methodology of testing where the marketer leads the test by forming hypotheses and then uses technology to perform the test, rather than letting the technology lead the test - as was done in days of old. Let’s be honest – we’ve all been there. You feel that you ‘should’ run an A/B Split test and so go to your technology, select to run a subject line test and out of thin air and with no research or hypothesis, throw together two subject lines to test. And then become disappointed because there wasn’t a winner due to the subject lines being too similar.
