Question 1

How long should a preheader be?

Accepted Answer

Aim for 40-90 characters. Mobile shows less (30-55 chars), desktop shows more (up to 140). Front-load the most important words.

Question 2

Should the preheader match the subject line tone?

Accepted Answer

It should complement, not copy, the subject line. If your subject creates curiosity, the preheader can hint at the answer. If your subject is bold, the preheader can add context.
