# Maintain a healthy mailing list with auto unsubscribe
> Auto unsubscribe removes Hard Bounced and Complained contacts to improve deliverability and ensure content reaches inboxes.
Kajabi helps you nurture a healthy contact list by **automatically unsubscribing** Hard Bounced and Complained contacts. The next time you send an email, you can feel confident knowing it will reach its intended destination. Auto unsubscribe improves your deliverability and ensures that your content reaches your subscriber's inbox.
## Understand auto unsubscribing
First, review what a Hard Bounced and Complained email means.
**Hard Bounces** (permanent failures) can occur if:
* The email address no longer exists
* The email address is invalid
* The domain doesn't exist
**Complained** emails are reported when a recipient marks an email campaign as spam.
Kajabi helps you with your [Hard Bounced and Complained Emails](../../marketing/email-campaigns/email-metrics-overview) by automatically unsubscribing the email address from your **Contacts** tab.
If a contact consistently hard bounces on the same site within a 4-day period (at least twice) Kajabi automatically unsubscribes the email address from your **Contacts** tab.
Unsubscribing contacts that have Hard Bounced or Complained reduces future bounce rates, helps maintain a good sender reputation, and helps you keep your contact list clean.
Learn more about [sender reputation](../../marketing/email-campaigns/sender-reputation-guide) for details.
Although the contact has been unsubscribed, you can still view the contact and even resubscribe them if needed. This ensures that a Hard Bounce from an email address does not occur the next time you send a marketing email.
## Review a contact list
Review your list and learn more about the subscription status of your contacts.
### Subscription status
View your contacts' subscription status and locate the contacts that have never subscribed, are subscribed, and have unsubscribed.
Included with the Unsubscribed status is the action that triggered the unsubscribe:
* **Bounced**: If a contact is determined to be permanently undeliverable, the contact is automatically unsubscribed.
**Note:**
You may encounter contacts in your hard bounced segment that remain subscribed. Your contacts will remain subscribed unless they are determined to be permanently undeliverable. As such, contacts may not be unsubscribed immediately upon a hard bounce.
* **Manual Unsubscribe**: You or one of your authorized users unsubscribed the contact. Or the contact manually unsubscribed from your email marketing by updating their [email preferences](../../contacts/manage-your-contacts/how-your-customers-can-update-their-email-preferences) from their account.
* **Opted out**: Contact opted out from receiving your marketing emails by clicking unsubscribe in the footer of the email received.
* **Marked spam**: Contact marked the email as spam in their inbox.
* **Never Subscribed**: Contact [added to the Contacts tab](../../contacts/manage-your-contacts/how-to-import-contacts-into-kajabi) without subscribing to marketing emails.

## Resubscribe unsubscribed contacts
As you maintain and review your **Contacts** tab, you may find emails that have been mistakenly unsubscribed due to a typing error when entering the email address, or a contact may have changed their email address.
To resubscribe a contact that may have been unsubscribed due to a typing error or a change in email address, complete a Double Opt-in Form for your contact. Using a Double Opt-in Form will require your contact to confirm their desire to subscribe to your marketing emails and can help aid in staying compliant with email laws (see Disclaimer).
If your customer wishes to resubscribe to your marketing emails from their account, read [update email preferences](../../contacts/manage-your-contacts/how-your-customers-can-update-their-email-preferences).
First, [create a Double Opt-in Form](../../marketing/forms/how-to-set-up-a-form-with-double-opt-in) to resubscribe unsubscribed contacts. Be sure to include any applicable [custom fields](../../marketing/forms/how-to-add-and-edit-fields-on-a-form) to capture additional information associated with your contact(s).
After creating your Double Opt-in Form, complete the form with your subscriber's correct information:
1. Open the **Marketing** tab from the Dashboard.
2. Click **Forms**.
3. Select the Double Opt-in Form you created to resubscribe unsubscribed contacts.
4. Click **Preview** in the top menu.
5. Enter the correct contact information in the form.
6. Then, **Submit** the form.
Because it is a Double Opt-in Form, your contact will need to confirm their desire to subscribe by clicking **Confirm subscription** in the subscription confirmation email received in their email inbox:
If your contact does not wish to subscribe, they can choose to ignore the email received and remain unsubscribed.
The Double Opt-in Confirmation Email is an automated email sent by your site when the double opt-in is enabled on a form. Read [edit automated email notifications](../../account-settings/notifications/edit-automated-email-notifications) if you wish to customize the text included in your automated email. Locate the Double Opt-In Email to customize.
**Disclaimer:** Manually resubscribing a contact after having unsubscribed may result in non-compliance with various electronic communication and/or data privacy laws. If your contact has been unintentionally unsubscribed, it is best to organically allow your contacts to resubscribe to your marketing emails with a form submission on your site.
