Preferred Billing Reminder Contact
Setting or Updating your Contact
- For customers who own or manage multiple domains names, it is possible that you will have more than one billing contact in your set of domains. To set your primary preferred billing reminder contact, choose the domain which has this contact from your list of domains, and then go to Contacts > Billing Contact.
- This contact is especially important for customers who are hosting their website and / or email with us, but do not currently have their domain registration with Register4Less.com (you really should!). In the past, if there was no registration here, we would not have a contact record for the domain, and thus would not have an address to email you renewal reminders.
- Once you have selected the "Make this my preferred billing reminder contact" option, review the contact information for accuracy, and then click the Save Changes button.
