What is the ideal length for a newsletter subject line?
Research shows that subject lines between 6-10 words or 30-50 characters tend to perform best. Mobile devices display around 30-40 characters, so keep your most important words at the beginning. Shorter subject lines generally outperform longer ones because they are fully visible on all devices.
