Private Domains

Private domains allow for receiving of email at any address within a domain. Private domains can be purchased as an addon or as part of a plan.

Zero-Setup Subdomain

The Zero-Setup Subdomain automatically creates a subdomain under msdc.co (eg test123.msdc.co) that is ready to receive email with no additional setup. This is the ideal option if you do not own a domain or do not have access to change the DNS records for a domain.

BYODomain

BYODomain (Bring Your Own Domain) allows you to easily receive email with a domain or subdomain you already own. If you do not already own a domain you can use our Zero-Setup Subdomain. Alternatively, you can purchase a domain from a registrar (Namecheap or GoDaddy) and configure it for use with Mailsac.

Zero-Setup Subdomain Configuration

Setting up a Zero-Setup domain only takes a few seconds.

3. Enter a subdomain name and select continue

3. Enter the fully qualified domain name of your domain

   Note

   The adding of DNS records will depend on your DNS name server. Your IT department may be able to assist with this. If you use your domain registrar’s name server they should have documentation on how to configure DNS (Namecheap , Godaddy Documentation).
