1 Secret, and 7 Best Email Subject Line Examples

This examination of the email subject lines in Amanda MacAuthor’s inbox on Mequoda.com is a great reminder that sometimes the best swipe file is right underneath your nose.

In it, she doesn’t just give subject line ideas, but why they stood out and grabbed her attention—a part of the process I think we should all consider more carefully. On a personal note, I know I don’t even bother with the “7 things to…” and “8 reasons why” emails.

That’s not to say they don’t work, I’m just saying that if I’m in your target demo, that’s not the best way to get my attention…

    Christopher Pontine

    • Ah, so I see my plan worked. Excellent ::sinister chuckle::

      I’m an AWeber customer & I love AWProtools because it allws me to tag subscribers, switch lists based on click behavior, and a whole lot more.

      They’re a former client, so I may be biased, but I think its amazing

  4. Terrific article. Many thanks for the tips and great work. I’ve recently found your blog posts and now I’m a daily reader. Cheers!

  5. Hi,
    Very useful article. Just wanted to point out one thing. I believe you met to refer to Senator Al Franken and not Al Franklin. Al Franken = Funny, Smart, Good Guy. Al Franklin = Huh? :-)

  6. Thank you! This certainly gives me some ideas!

  7. Great compilation of subject lines! The interesting question is whether subject lines we like from a creative standpoint are truly successful and if there’s a strong link between subject lines that sound great and subject lines that deliver opens and clicks. A/B testing lets us explore this question, but it takes time and often by the time a statistically significant result is achieved, the offer has expired, the product is out of stock or business need has changed. That’s why we developed Touchstone, a tool that compares your proposed subject line with a database of 110,000 (and growing) database of other subject lines and results. It can predict open and click rates for a given subject line before you send anything so we’d recommend anyone with an interest in this area gives it a try – it is currently in open beta and free to beta users, try Touchstone at http://www.subjectlinegold.com

    topic for a long time and yours is the greatest I’ve found out till
