Step 1 - Single Opt-in vs Double Opt-in

Before getting started, you need to decide which opt-in signup method you would like to use for your subscribers.

With Single Opt-in method, when your website visitors fill out the sign-up form and click the submit, they will be subscribed to your email newsletter immediately.

With Double Opt-in method, MailChimp will send them an opt-in confirmation email, they will only be subscribed to your email newsletter when they have clicked the link in the email to confirm.

In Wonder Popup, you can choose the opt-in method in the Email Service tab.

Step 2 - Final Welcome Email vs Automated Welcome Email

In MailChimp, there are two ways to send automated welcome email to subscribers: Final Welcome Email and Automated Welcome Email.

If you use Single Opt-in sign-up method for your subscribers, you can only choose Automated Welcome Email.

If you use Double Opt-in sign-up method, you can choose either Final Welcome Email or Automated Welcome Email. Please make sure you only enable one method, otherwise your subscribers may receive duplicated emails.
