**What do you like best about Coldsire?**

That I know what I am being billed for and that everything is in one platform.

**What do you dislike about Coldsire?**

Pricing is more expensive then compedtors who CLAIM they do the same thing.
I am not technical enough to understand if they actually do the same thing.

**What problems is Coldsire solving and how is that benefiting you?**

They help us scale our cold outbound. Logistically it is very complex if you have to setup every domain and inbox and attach it to your sending software, they do this for you.
