Remember, though: there's good attention and bad attention.
Some bad ideas
There are lots of things that can cause your email message to be seen as spam. Below are some things to avoid:
- All uppercase letters (SHOUTING)
- Exclamation marks (Big Sale!!!)
- Dollar signs ($ave $ave $ave)
- Asterisks (*** Move me to the top of the inbox ***)
Most people won't even open these messages, and any future messages from you might be ignored or even blocked.
A better way
Make the subject line clear and easy to scan. Try to get the most important information into the first two or three words. Use descriptive and appealing words, rather than punctuation, to get the reader's attention.
You can also try out different subject lines on small subsets of your mailing list. Use response reports to see which one generates the most opens and the most responses.
