How to Enable Single-Optin for MailChimp in OptinMonster

Share This Post

Most email marketing service providers frown upon single optins, but several do offer the option to enable it. MailChimp, one of the popular email service provider, allows you to enable single-optin by using their API. Since we already use the API to connect with MailChimp, several of our customers asked us to add the ability to disable double-optins and enable single-optin for MailChimp.

We didn’t want to add a user-interface for this setting because it is not possible for other integrations. If you’re using MailChimp and want to enable single-optin, then simply paste the following code in your theme’s functions.php file:

add_filter( 'optin_monster_mailchimp_double', '__return_false' );

This will disable the default double-optin, and users will be added to your email list without having to confirm their email address.

    If you select MailChimp as your provider is it not possible for you guys to make it so that it then displays this as an option? I’d like to use double-optin for some things like regular newsletter signups, but single-optin for situations where I’m using a lead-magnet and some other form of delivering the second e-mail. If the option only appears after you have selected an integration that supports it then it shouldn’t cause any issues no? This is forcing me to choose one method or the other.

      I have not implemented this yet, but plan to. But, I agree with Dan here – we have a general email list that we’ve always run with Double Opt In. But now, with the help of your system, we’re delivering some Autoresponse Free Stuff and we’d want to have it Single Opt In. Would be nice to have it selectable on a case-by-case basis – or I should say Optin-by-Optin basis ;)

    What about in GetResponse?

      Hi there,
      GetResponse requires double optins for all emails using their API.

      You can email them and ask them to turn it off by emailing them as described here: support.getresponse.com/faq/how-i-edit-opt-in-settings
