Hi Tammy D., David is mostly right but it is also about the offer you are pitching and also you know that market has recently gotten crowded and everyone is sick of receiving 20-30 cold mails a day. But still people are closing deals based on the value they are providing. Key things to focus on are quality infrastructure, focus on elaborating the value business will get from the services also dont use too salesy language as it kills deliverability and force the reader to mark your mail as spam and also try to be straightforward and provide competitive pricing, reader is not a child that he/she will read a good story and will be convinced to buy, he is a mature person running a business he will always chase the value that makes his/her business more profitable. (Golden words BTW)
