1. Navigate to the MX Records page on your hosting provider’s website. If you’re unsure who your hosting or DNS provider is, please contact your website administrator.

  2. Create a new MX record for the subdomain (e.g. parse.yourdomain.com or reply.yourdomain.com) you want to process incoming email.

        This hostname should be used exclusively to parse your incoming email.
        Do not change the MX record for your domain. If you do, you will no longer receive email.
  1. Assign the MX record a priority of 10, and point it to the address: mx.sendgrid.net.

It should look something like this:

If there is no field for priority, type 10 before the address. e.g. 10 mx.sendgrid.net.
