Let’s kick off this post by defining single optin and double optin:

Single Optin: An email subscription method that requires the user to submit their details. In this method,  the user is immediately added to the subscriber list, without having to take any further steps.

Double Optin: An email subscription method in which when a user submits his details, a confirmation email is immediately sent to the address they provided. This confirmation email contains a verification link, which the recipient must click to confirm that they own the address. When the link is clicked, the person’s email address is added to the subscriber list.

The reason we recommend single optin for our MailChimp integration app is simple – Think about it this way: When a new customers buy something from you, they already gives you permission to communicate with them. These customers are willingly giving you money for a product, so it makes sense that they would want to have a direct communication channel with you for support or future product updates.

The reason email marketing software companies recommend double optin is because they refer to different email-collection situations (like a user that signs up for a newsletter on a website). In these situations, the prospective customer just shows a little bit of interest (he really hasn’t pulled out his wallet and paid you), so in these situations it’s better to use double optin, just to verify that the user really wants to get future communication from you.

I hope you can see our logic behind the single optin vs. double optin debate.
