Exciting subject lines!
Make sure your subject line is attention grabbing, engaging, personal and relevant to encourage your readers to open the email.
Don’t overuse CAPITAL LETTERS and remember that some words will trigger spam filters. Use these words
instead – including the occasional exclamation mark!
Try and keep your subject lines to 61-70 characters. And maybe even include an emoji in your subject line.
Experian noted that 56 per cent of brands using an emoji in their email subject lines had a higher unique open rate.
