Reconfirming your list is a process of removing email addresses from your list that are no longer engaged or valid, leaving only the subscribers who want to receive and engage with your content. When someone opts-in to your MailChimp list, they're giving you permission to send your campaigns to them. In general, permission tends to go stale after about six months. If you have subscribers you haven’t sent to in the past six months, you need to reconfirm their permission to be on your list before you send to them again.

We strongly recommend that you always use our double opt-in process, including when reconfirming a list. Double opt-in reconfirmation helps focus your list on engaged subscribers who want to hear from you, which leads to more opens and clicks, and fewer bounces and unsubscribes.

Below, you’ll learn how to reconfirm an existing list in your MailChimp account as well as how to import and reconfirm a list not yet in your account.

Reconfirm a list not yet in MailChimp

If you have collected a list of contacts outside of MailChimp that is more than six months old, you need to reconfirm your list before you begin sending. First, you need to create a new list in MailChimp and get the link for its signup form.

  2. Click the Create List button in the top-right corner.
  3. Click Create List from the New List or Groups option window.

To reconfirm your list, you need to send a reconfirmation message to your subscribers with the link to your signup form. Below, you’ll learn where to get the URL for your list’s signup form so you can include it in your reconfirmation message.

Copy the link to your MailChimp signup form

  1. Navigate to the Lists page.
  2. Click the list drop-down menu and select Signup forms for the list you're working with.
  3. Select General forms.
  4. Make any changes you’d like to your form and then copy the Signup Form URL from the Create Forms page.

Send a reconfirmation message

To send your reconfirmation message, create a brand new email outside of MailChimp in your regular email program, such as Gmail or Yahoo. You can copy the addresses from your exported CSV file into your regular email program to send your reconfirmation. Add the link to your MailChimp signup form to the body of the email along with a message asking your recipients to resubscribe to your list. Be sure to send the email from an address that can be linked to your personal, company, or blog website. You might also wish to include links to your past newsletters or link to a new sample newsletter you've created.

Note

It's important that you send reconfirmation emails from outside of your MailChimp account or your account will start sending up red flags. Protect your reputation and send your reconfirm message outside of MailChimp in a personal email account.
