Along with email marketing, GetResponse offers landing pages, opt-in forms, webinar hosting, a CRM tool, and plenty of other marketing automation tools.
Just like AWeber, GetResponse has two affiliate programs you can choose from (or, you can join both!):
Their self-hosted program offers a 33% recurring commission. With plans ranging anywhere from $15 to $1,200/month, the payout can be pretty substantial.
You can also earn $135 for every sale referred through CJ Affiliate. However, the cookie life is only 30 days, rather than 120 offered in the in-house program.
