A quick mini-thread on how the @MorningBrew picks our Subject Lines for each email (cuz its probably not how you think)
First off, we actually do A/B test our subject lines

we send the email out early to four separate batches of ~80,000 readers

each batch gets a different subject line

whichever one has the highest open rate goes out to the remaining 1.8 million readers
But subject line picking isn't actually as scientific as you might think

we just skim the newsletter stories for interesting and eye-catching phrases

then one writer picks them for the day and we roll with whatever they choose
When i joined the Brew, this process was v surprising to me

the perfect blend of:

-art (just pick cool sounding phrases)
-science (we do A/B test)
-trust (any writer can pick them on any day)
Final note, for some reason we abbreviate Subject Line as SJ

still havent been given an adequate explanation of why that is lol
