Easy to use and a great API

My requirements were simple, a single list of customers that I send a quarterly newsletter to. Noptin allowed me to compose the newsletter, import a list of customers, and then send emails. No problem. Well, not entirely, there are still those pesky email servers that block mail based on SPF and DKIM, so I had to configure some email options. I was still getting some issues so I switched out to smtp2go in order to send my emails. This seems to be working better.

Lastly, the API is working really well. When a customer is logged into the SAAS they can toggle an option to receive the newsletter, at which point I send an API request to toggle the email address – works great.
