I got my first customer for the weekly plan on my newsletter-as-a-service product www.emailatscale.com!
This was from a previous client for whom I was doing email automations. He was having trouble finding new content to promote to his list every week and he saw the longer he spent without contacting his list the lower his overall open rates became.
I showed him how I'd doubled the open rates for a previous client with a redesigned weekly newsletter and sent a link to my landing page 👍
