I am wondering if its possible to email them all at once? I have a new IM type offer I wish to send to these people. Is there software I can use to send them all the email without them being on an 'opt in' list?
Sorry for my ignorance here, I am new to email list, email marketing etc.
If I can chuck all the email addresses into some kind of software and send the 1 email that would be great.
any advice, please shoot my way
