Each Mailchimp audience comes with an associated signup form, which you can customize and share on your website and other networks. Forms use a single or double opt-in setting that determines what steps are taken before a contact is subscribed to your email or SMS marketing.

In this article, you'll learn how to choose opt-in settings for your audience.

Note

Opt-in settings only apply to Mailchimp signup forms, so form integrations and API opt-in are unaffected.

About opt-in

Mailchimp audiences use single opt-in by default: Someone fills out and submits your form and they're added to your audience as a subscribed email or SMS contact right away. Double opt-in requires that people confirm their signup via email or SMS. Both methods are easy and secure options for growing your audience. You’ll decide which method works best for your needs.

Single Opt-In vs. Double Opt-In

Note

  • If your primary contact address is in the EU, some of your audiences may be double opt-in. If you prefer to use single opt-in, you can make that change in each audience's settings.
  • Double opt-in is required to send abandoned cart text messages.

For a new audience

When you create a new audience in Mailchimp, you'll choose the opt-in setting you want to use with its associated signup forms.

To use double opt-in for a new audience, check the box next to Enable double opt-in to send a confirmation email each time someone signs up to your email marketing. Leave the box unchecked to keep your audience single opt-in and add new subscribed email contacts right away.
