To the Point: Keep Your Year-end E-mails Off the ‘Naughty’ List

7. Forgetting to test.
By taking a few minutes to send a test to yourself and a few colleagues, you can have peace of mind that your links work, your copy is typo-free and everything looks just the way you thought it would — all before you send it to the big list.

8. Writing — and sending — a novel.
Don’t send a really flippin’ long e-mail. When you send a campaign that goes on and on (and on), a typical subscriber — with a typically short attention span — probably won’t sift through lots of text to find the content that interests him. Instead, he might delete your e-mail at a glance.
