Q: I have a list of 20,000 opt-in small business owners. How much do you think could be made each month with affiliate offers?
A: There are a lot of factors that will determine the affiliate commissions you can earn monthly from a given e-mail list: how often you mail to them, open rates, age of the list, etc.
I would suggest having a look at the various affiliate and CPA networks to scout out offers that will appeal to your audience.
Also, have a look at DataOverdrive. They offer list management, list brokerage and data hygiene services.
After you’ve settled on some offers you’d like to test, try sending them out to a sample of your list – maybe 10-20% of your subscribers – to see how they respond. Don’t send new offers to your whole list.
