4 tips for writing email subject lines that increase your open rates
Follow these best practices for writing email subject lines to skyrocket your email open rates.
Tip 1: Keep your subject lines under 50 characters
Shorten your email subject lines. Keep them less than 50 characters so none of your important words are cut off on small screens.
Also, use email marketing software that shows the number of characters on your subject lines to manage its length.
Tip 2: Know your audience
Understand your audience to create attention-grabbing subject lines that resonate with them.
When you have a clear picture of your audiences’ quirks and qualms, it’ll be easier to write compelling subject lines. Couple this strategy with email newsletter best practices and you get the winning combination to grow your email marketing ROI.
Tip 3: Perform split tests
Write different versions of your email subject lines and test which one gets the best response. Split tests help you discover which among the many subject lines you’re using are bringing in meaningful results.
As you uncover which subject lines are performing well and which ones aren’t, optimize your campaigns by investing more in high-performing emails while discontinuing those with poor performance.
Tip 4: Keep a swipe file of great subject lines
When you come across amazing email subject lines from companies that are sending you emails and newsletters, save them. Store them on your computer’s notepad or a cloud-based spreadsheet.
