# 30971: Campaign rejected: Business email must use official domain

Log Type: APPLICATION

Log Level: ERROR

## Description

Your A2P 10DLC campaign was rejected because the business contact email address uses a free or unofficial email domain. Campaign registration requires that the contact email use your company's official domain (for example, name@yourcompany.com) rather than a generic consumer email provider. This requirement helps verify the legitimacy of the business and its association with the registering entity.

### Possible causes

* **Free email provider used:** The contact email uses a free email service such as Gmail, Yahoo, Hotmail, or Outlook.com instead of a company domain.
* **Personal email submitted:** A personal email address was provided instead of an official business email.
* **Domain mismatch:** The email domain does not match the business name or website domain provided in the registration.

### Possible solutions

* **Use your official business email:** Update the contact email to one that uses your company's official domain (for example, yourname@yourcompany.com).
* **Verify domain ownership:** Ensure the email domain matches the business website and registered business name.
* **Set up a business email:** If your company does not yet have a custom email domain, set one up through your domain registrar or an email hosting provider before resubmitting.
* Once corrected, resubmit your campaign for review.
