About Double Opt-In

MailChimp offers two signup methods for your lists: single opt-in and double opt-in. Both methods collect email addresses easily and safely and help you grow your audience. Depending on your organization’s needs, you may want to try the double opt-in method, which includes an extra confirmation step that verifies each email address.

In this article, you'll learn about the double opt-in process and how to use it.  

How Double Opt-In Works

The double opt-in process includes two steps. In step 1, a potential subscriber fills out and submits your online signup form. In step 2, they'll receive a confirmation email and click a link to verify their email, which is added to your MailChimp list.

Turn on Double Opt-In

You can choose to enable double opt-in when you create a new list in MailChimp. Or, if you have an existing list, go to your list settings to turn on double opt-in. You can take a look at the subscriber activity for individual lists in your account to determine if any of them may benefit from the double opt-in process, which can help improve open rates.

Customize the Double Opt-In Process

You can customize your double opt-in process in the Forms and response emails section of MailChimp's Form Builder.

In the Form Builder, you'll design your MailChimp signup form and your response emails that guide your potential subscribers through their double opt-in signup.

Think of these documents as your opportunity to onboard new subscribers and introduce them to your brand. You can add branded assets and custom text to your form, or enable a welcome email with a coupon or special offer for new subscribers.

These messages are included in the double opt-in process.

  • Signup form
    The signup form is the first experience your potential subscribers will have with your brand. They'll fill out the form and click to submit it.
  • reCAPTCHA confirmation
    After someone fills out your signup form, they'll need to check a reCAPTCHA box. This required step keeps spambots from adding fake data to your list, and can't be turned off or edited.

  • Signup thank you page
    This page tells your potential subscriber to check their email for a confirmation message. If you don't want us to show this page, redirect to a custom signup thank you page on your website.

  • Opt-in confirmation email
    The confirmation email contains a unique URL that your potential subscriber must click before we can add them to your list as a subscribed contact. Customize the text and design of the email to match your organization's branding and style.

  • Confirmation thank you page
    Subscribers see this page after they've clicked to verify their email address. You can also redirect to a custom confirmation page on your website.

  • Final welcome email
    This optional email is disabled by default, but you can enable a welcome email at any time. We'll deliver this email after a subscriber confirms their subscription and sees the confirmation thank you page. Some people use this message to send their new subscribers a welcome message, coupons or promo codes. You can also accomplish this with an  Automated Welcome Email or email series.
