Single Opt-in vs. Double Opt-in: The Court of Public Opinion
The case has been made for single opt-in and the case has been made for double opt-in. This contest is clearly one of great public interest, judging by the number of people who have testified by commenting and by the reactions of people on Twitter and elsewhere.
These comments deserve consideration and the public’s opinion will be heard, but first let’s again be clear on who the two parties are in this dispute:
- Single opt-in (SOI) is a subscription process where a new email address is added to your mailing list without requiring the owner of that email address to confirm definitively that they knowingly and willingly opted in
- Double opt-in (DOI), also known as confirmed opt-in (COI), is a subscription process where a new email address is only added to your mailing address after the email address owner clicks a confirmation link in a subscription activation or opt-in confirmation request email that’s sent to them after they opt in via a form or checkbox
With those formalities out of the way, let the voice of the people be heard!
