We narrowed down our list by eliminating vendors that don't specialize in email marketing campaigns or that don't work with small businesses. Next, we researched each provider by investigating its services. We considered pricing when available. After narrowing the list down to seven, we contacted each company's customer service department and posed as small business owners.

ProtonMail is a basic email service that is easy to set up because it doesn’t ask for any personal information. You just pick a user name and password, and you’re set. Be aware that some features – such as mail collection and the ability to sync across multiple devices – are only available with its paid email service. But the free version does have email encryption, which is important if you send messages with sensitive information you want to protect. ProtonMail automatically unencrypts the message when it reaches the recipient’s inbox and is opened.

We also tried to keep in mind that all of this influencer outreach was not only about the short-term benefit of acquiring links, but it also served the purpose to stake out a place in the customer success space and build relationships with important, smart people.
