I'm liking the pricing with you guys, I have a list of contacts currently around 5k that will probably take awhile to grow to 10k that I wouldn't mind paying $10/m to send monthly emails to. Now again I want to send a warm "open" to them to update their subscription settings and whatnot but since many may be a little old (we rarely sent emails except direct correspondence) I'm super concerned about people hitting "mark as spam" and it becoming an abuse complaint resulting in domain blacklists. I did a 2k run on an actual newsletter with mailchimp and 4 people did that. About 19 unsub'd which is fine. Any advice?
