Frequently Asked Questions
How are email subject lines related to SEO?
While emails aren't indexed by Google, email marketing drives website traffic, increases brand searches, and promotes content that earns backlinks - all supporting SEO indirectly. Good subject lines increase open rates, driving more traffic.
What is the ideal email subject line length?
41-50 characters (or 6-10 words). Mobile devices show only 30-40 characters, so front-load the most important words. Personalized subject lines with the recipient's name increase open rates by 26%.
What words boost email open rates?
Power words like 'exclusive', 'limited', 'new', 'proven', 'secret', and 'free' increase opens. Numbers and specific data points (e.g., '37% increase') also perform well. Avoid spam triggers like ALL CAPS and excessive exclamation marks.
