Hello, I have an email list of potential leads that I was given for my business but don't know what the best option out there is. I would like a service that will clean my list prior to sending (if possible). I did a quick G search and found multiple companies but sites like Aweber, mailchimp, etc all require an opt-in prior to sending out mail. Is there a reputable company out there that will allow me to just pay a monthly fee and have them send out the emails for me without requiring all the opt-in BS? Thanks in advance.
