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.

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.

BYODomain Configuration

BYODomain configuration requires you to have access to modify DNS records on your domain.

1. From the dashboard, select Verified Domains.

   

2. Select “Setup a Custom Domain”

   

3. Enter the fully qualified domain name of your domain

   

4. Select the DNS Setup Tab to configure DNS

   

   Note

   “Not Verified - Action Required” indicates DNS is not properly configured.

5. Configure TXT DNS record for DKIM

   Create a TXT record for DKIM with the hostname and value found on the DNS Setup page in the Mailsac dashboard.

   

   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).

1. Verify DNS Settings

   Click the “Query My DNS Settings Now” button to verify your DNS settings.

   

   Note

   DNS can take up to 24 hours to propagate

2. DNS Setup Complete

   DNS setup is complete when the status message changes to “We have verified that the DNS settings below were added correctly”.

   

Email can now be received and sent from your BYODomain!

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.

Zero-Setup Subdomain Configuration

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

1. From the dashboard, select Verified Domains.

   

2. Select “Setup a Custom Domain”

   

3. Enter a subdomain name and select continue

   

4. Send a test email to any address at in the private domain. There is no need to configure individual addresses. Sending an email to the address creates the address.

5. Enter the email address you sent the email to.

   

6. Verify the email was received.
