Back in 2015, Return Path took a deep dive into emails from a whopping 2 million subscribers, aiming to spill the beans on better open rates. Most subject lines hung out in the 41-50 character zone, but subject lines 61 – 70 characters long had the highest read rate (17%).
After investigating character subject length from 0-100 words, the result was “actually no correlation between the length of a subject line and its read rate.” But that data only tells part of the story. Many articles about email marketing best practices tout the importance of having a shorter subject line but need to connect all the potential factors as to why that might be true.
On a desktop screen, you’ll see around 60 characters of your subject line, whereas if you’re on mobile, you’ll only see about 25-30 characters. Meanwhile, statistics say that over 61.9% of emails are opened on mobile devices by subscribers for checking their inboxes.
