Verifying Domain Ownership

Learn how to verify a domain you own, so that you can use it with your Mailosaur account for email and SMS testing.

Why verify a domain?

There are 3 main reasons for verifying ownership of a domain:

  1. To use a custom inbound domain for emails sent into Mailosaur (Professional and Enterprise plans only).
  2. To use the mailosaur.js library (e.g. with Ghost Inspector).
  3. To send, reply and forward email to external email addresses on that domain.

Verifying ownership of a domain

  1. Log into the Mailosaur Dashboard.
  2. Navigate to the Account Settings area ( icon in the top-right of the screen).
  3. Select Domains.
  4. Enter the domain name you want to verify (e.g. example.com), and submit the form.
  5. You will presented with on-screen instructions on two methods of verifying ownership.
  6. Once you have followed the on-screen instructions, it may take up to 30 minutes for the domain to be verified.
  7. Once a domain is verified, you’ll see a green checkmark next to it, meaning it is ready to use.

Using a custom inbound domain

Note: Only available to Professional and Enterpise plan customers.

By default, Mailosaur gives you access to addresses ending @{server_id}.mailosaur.net. You can, however, use your own domain instead (e.g. @{server_id}.yourdomain.com)

To do this, follow the instructions below. Note that these instructions require access to the DNS records of your domain, as well as technical knowledge. Share this information with an IT team member if this is not your thing.

Linking your domain to a Mailosaur server

  1. Verify ownership of the domain by following the steps above.
  2. Find the subdomain for your Mailosaur server (this can be found in the Server Settings section, within the Mailosaur Dashboard).
  3. Create a new MX record for the domain that you want to point to Mailosaur, using the subdomain from the previous step, for example:
    Host NameMail Server
    {server_subdomain}.yourdomain.com0 mailosaur.net.

It can take up to 24 hours for new DNS records to propagate, but once set up, any email sent to email addresses ending with @{subdomain}.yourdomain.com will appear in your Mailosaur inbox.

Using a wildcard configuration

If you want all email sent to a particular domain to go to Mailosaur, then you can add a wildcard record. Note that you should only do this if the domain is solely for use with Mailosaur.

  1. Verify ownership of the domain by following the steps above.
  2. Create a new MX wildcard record for your domain:
    Host NameMail Server
    *.yourdomain.com0 mailosaur.net.

It can take up to 24 hours for new DNS records to propagate, but once set up, you’ll be able to send email to anything@{server_id}.yourdomain.com.
