hey fam, sorry if this was addressed already! I was looking at mailierlist MailerLite and a few other ones, but seems like i can do everything from SendFox? And have been a user for some time. So 2 questions: 1) i see the single opti-in is optional? can you share more on that? I know it's up to us to do it and i know that double opt-in is preferred, but i think it's a better UX without it - so what's the downside of turning it off?
2) we can connect our domain and have the emails go out from our domain - is there a downside to this? would hate our domain spam score go up. Thank you!
