I have made a list with over 1000 businesses (medium to large) that I wanna target and sell my service to.
I´ve sent out a sales letter to about 500 so far, and I´ve actually had SOME sucess. Got 3 callers back within two months, and I´m pretty sure at least one of them got the mail and found it interesting because they said "hello, we read your mail and we´re interested bla bla.."
But since they are cold mails I have no idea how many actually gets to the recipent. My mail was sent from one.com mail service. It was an image in the mail with mostly text but also some graphics.
Should I try to start from the top now (couple months later) and send out mails with written text (html) instead? Are there any tools I can track my cold mails with?
I feel like emails should be my number 1 card, but I have really no idea on what to do..
