Hi all! I'm really new to mailing and I have just been sending out newsletters to my community of subscribers for over a year now. I never really knew that instead of asking for donations and funding to pay for the website to stay up I could do some marketing instead. So for the last couple of months I've read up on email marketing, setting things up and getting ready to do this. A few questions surficed during the last week and I've been trying to understand the laws and the CAN-spam act to avoid breaking it. I want to be all legal with this as my community and website has a reputation and "brand" in my niche. So, currently I have what some of you would consider a small list, 100k of users that signed up to the website, in my TOS I have clearly stated that by signing up they approve me aka "the website" to send them information or emails. So I feel secure there. But since I will be running this marketing campaign from an external source, an email marketing service, I've been wondering about the opt-in liability. How does one prove (incase it's needed) that the list actually IS opt-in? I really can't afford to begin my email marketing journey with being questioned by this email service and not having proof or knowledge as to how one presents that a list is opt-in. So I'm turning to you guys, what should I think about before starting my email campaign? How do I prove that my list is opt-in to an external mailing service provider? If I'm unclear of anything here or made a mess with my questions, let me know! I'll try to answer as best as I can! Thanks for reading this!
