If I ever write a book on email marketing (oh, wait I did, ahem, another book) it might be called “It depends.”
What’s a good email response rate?
How many people will click?
How many people will open it?
Same for pop-up conversion, signups to newsletters, direct mail, AdWords….
There are many variables that can affect the response you get from a mailing.
The three biggest are:
1) the quality of the list you use (the audience)
2) the offer – is it any good?
3) the creative (copy and graphics) in the email and on the landing page – this includes the words, the typeface, any photos or illustrations, the colors of the buttons, the button text, and the call to action
1) the time of day
2) the day of the week
Spend most of your time on the first three. Then worry about the last two.
