Clarity is key here. Your sign up form should explain the benefits of signing up for your email list, information about the types of content you’ll be sending (newsletters, product promotions, etc.), the cadence of your emails (i.e. weekly, monthly). When you define these expectations up front, your subscribers won’t have any questions about what they signed up for.
I have very deliberately included two blogs above that have absolutely nothing to do with making money or online business in any way shape or form. That market is arguably the hardest to make money in, because it is so saturated. Thanks to Chris Guthrie for making the very sensible suggestion that I should include non-MMO blogs in my examples above.
Think about implementing referral links to incentivize your subscribers to spread awareness about your brand, too. Referral links allow your current customers to promote trackable links for your business. In exchange for sending new paying customers your way, you can give them incentives like discounts, coupons, vouchers, cash, prizes or redeemable points.
