Suggested subject line

Why are email subject lines important?

Win Goodbody

A subject line is like a newspaper headline, a title on a book’s spine, or the key slogan of a print media ad. It tells the user what this is all about. And it should do so in sparkling style — seamlessly channeling your brand.

When it comes to email marketing, the best subject lines tell what’s inside, and the worst subject lines sell what’s inside.

Nothing says spam quite like a shouty, capped up subject line. It makes it difficult to read and is unlikely to have the desired effect of grabbing the reader’s attention.
