An author who I consider rather successful told me this morning that when she (her assistant, actually) sends out her newsletter, a few days later they'll send the exact newsletter out again to everyone who didn't open it the first time. They just change the subject line. She said that 30-65% of the people who didn't open the newsletter the first time will open it the second time. I thought that was wild! Has anyone here done this? Did/do you see similar results? I was thinking about trying it.
