If you’ve been wondering what Mailchimp’s Single Opt-In is all about and whether to go with it or keep your double opt-in, I’ve found the article for you. Kirsten Oliphant has the scoop:
Single Opt-In: Essentially when someone enters their email into your form and clicks “I Want It What Way!” (because “Subscribe” is so 2011), they are automatically subscribed. Right then and there. The end.
Double Opt-In: When someone enters their email into your form and clicks “Send Me All The Things!”, they will receive an email asking them to confirm. If they do not click, they will not get an email from you. They are not, in fact, a subscriber.
Single opt-in is not legal all over the world. (True story.) The un-apt-ly named CAN-SPAM Act (which says you CANNOT, in fact, spam people) doesn’t care about opt-ins, surprisingly. You can single opt-in all day long legally in the USA and many other countries.
Just not Germany.
I’m sure there are others, but Germany has super strict laws on privacy. So if someone from Germany signs up through your single opt-in form, you’ve broken their laws.
Are you really going to be hunted down or fined? Probably not.
But do you want to be breaking international laws when you send emails? Um…probably not.
