Long subject lines also give you the opportunity to include keywords and phrases that resonate with your audience, increasing the chances of your email getting noticed. Additionally, they provide you with more room to highlight the benefits or offers you’re presenting.

So, take advantage of the effectiveness of longer subject lines to increase your email open rates and engagement.
