I take your point re: deliverability though the email address for my new company that we use for all gaming related affiliate programs has none of the typical spam filters.
I’d hate to miss the email that said ‘Mark, because you’re such a charming and handsome chap, here’s an extra £5k in your affiliate account. Please reply to this email to confirm that you are as handsome and charming as we suspect’.
Edited To Add : Good choice on NetRefer software for the new program by the way. My personal favourite.
