Best Subject Lines of 2021
Every year, I listed the best email subject lines according to my personal email inbox.
My Totally Biased Judging Methodology
- 3rd place – You are on the list. Sometime in the past year, I opened one of your emails and thought, ‘Hey, that got my attention.’ I put a label on your email so you would be on this list when it came out.
- 2nd place – You are on this list more than once.
- 1st place – You have written more subject lines on this list than anyone else.
Since I subscribe to digital marketers and sales leaders, the content of the subject line skews to that school of thought. But I follow these people the most because they write the best email subject lines, and are more likely to contribute to my swipe files.
