Heath Atwood
Email Marketing Expert
When I signed up for MailTester.com, I was a bit skeptical at first. How much difference can it make for a relatively smaller company like us? Answer: a lot. We didn’t change our email strategy much still our email open rate has increased like 3-4%. I recommend MailTester.com.
