In each e-mail I provide something of value and then promote a relevant product with it. Which means that I almost promote a different product each week. Only a few get regular promotion (the ones I really like and think will benefit people the most).
What do you guys do?
I can see how on one hand people will appreciate the novelty on the other hand there is the idea that people won't buy something until they've seen it 6 or 7 times.
What do you think?
