Hey,

It was nice speaking to you the other day, this is the service I was telling you about that helped us boost our ROI almost 2000%

Its a company called Lifemail.studio sorry it took so long to get back to you. They allow you to send any email doesn't matter what.

We dealt with a guy named Michael, he was friendly and got us setup really quickly.

Regards, Lydia
