# About the Email Subscriptions API

The Email Subscriptions API is a service
that allows you to create, view, and update email subscriptions
for a site's contacts.
Any changes made with the Email Subscriptions API
are reflected in the site's [contact list](https://support.wix.com/en/article/about-your-contact-list).

Wix keeps track of contacts' subscription and deliverability statuses.
These statuses are automatically updated by Wix,
although Wix users can
[change subscription status](https://support.wix.com/en/article/changing-the-subscription-status-of-a-contact)
in the site Dashboard.  

The Email Subscriptions API allows you to:
- Query existing email subscriptions.
- Update or create subscriptions by email address.
- Generate unsubscribe links for individual recipients.
- Listen for changes to subscription statuses for site contacts.

## Sample use cases
+ [Check Wix for subscription status before a campaign](https://dev.wix.com/docs/rest/crm/communication/email-subscriptions/example-flows.md#check-wix-for-subscription-status-before-a-campaign)
+ [Sync subscription status with an email marketing tool](https://dev.wix.com/docs/rest/crm/communication/email-subscriptions/example-flows.md#sync-subscription-status-with-an-email-marketing-tool)

## Terminology
- **Email subscription:** Object that includes an email address, subscription status, and deliverability status.
- **Subscription status:** Whether a contact has opted in or out for marketing emails.
- **Deliverability status:** Whether emails to this contact were opened or bounced, if the contact marked an email as spam, or if no activity has been reported to Wix.
