Before you hit “send” on that fabulous newsletter remember, email domains often limit the number of subject line characters they display in the inbox*:
- AOL, (approximately 22% of the U.S. email market) limits subject lines to roughly 38 characters
- Yahoo!, (with 21% of U.S. email) is at 47 characters
- Hotmail, (14% of the U.S. email market) uses word wrap to display subject lines on multiple lines, but still just 45 characters per line
Bottom line: go for the lowest common denominator (38 characters).
Here’s a wrinkle: Considering the growing reliance on mobile devices, with smaller screens, think even shorter!
If you’re a Twitter-er, you’re probably getting used to truncating…I know I am.
