Generate leads automatically with Cold Emailing

Before we started working at Instantly, we had an agency and sent a lot of cold emails. The thing is, we were paying around $800 a month for warm-up and emailing services.

This was one of our biggest costs and we really wanted to see if there was a way to create our own warm-up and shipping service so we could save that money monthly. After our developer researched the architecture needed to build this, we had the exact same question as you. Are we missing something or is everyone overcharging?
