You don’t even have to think you’re a spammer to feel bad. Many of us feel bad just for sending too many emails. Often solopreneurs are downright terrified of sending an email update to their subscribers. They say they don’t know what to say, but I think it’s that they’re afraid, somehow, that they’re bothering their subscribers. They aren’t sure they deserve to be in their inboxes, even if those same people signed up for their emails (through a double opt-in process, of course).
Testimonials – If you work with contractors or freelancers, you can reach out to them to offer your testimonials in exchange for a link. Moreover, if you are using consultants’ or specialists’ services, you can also do the same as you do with contractors. Lastly, if there are customers who are happy with your product or service offering and they do not mind you linking to their site, this could be a good opportunity for your business.
