Our platform allows you to verify your domain for sending emails and set up branded links. Follow the steps below to configure the necessary DNS records.

1. Email Domain Verification

To send emails from your domain using our system, add the following DNS records. These ensure that your emails are secure, authenticated, and trusted.

Required DNS Records

Type Host Value
CNAME xxxxx.yourdomain.com uxxxxxxxx.wxxxx.sendgrid.net
CNAME s1._domainkey.yourdomain.com s1.domainkey.uxxxxxxxx.wxxxx.sendgrid.net
CNAME s2._domainkey.yourdomain.com s2.domainkey.uxxxxxxxx.wxxxx.sendgrid.net

Why These Records Are Important

  • CNAME: xxxxx.yourdomain.com
    This connects your domain to SendGrid, authorizing them to send emails on your behalf.

  • CNAME: s1._domainkey.yourdomain.com and s2._domainkey.yourdomain.com
    These records enable DKIM, which adds a digital signature to your emails, ensuring they haven’t been altered and reducing the risk of being marked as spam.

You can create branded links to provide a seamless experience for your users. Add the following DNS record:

Type Host Value
CNAME app.yourdomain.com customapp.web.app

Why This Record Is Important

This record allows you to use your own domain (e.g., app.yourdomain.com) for links that redirect to our platform (e.g., customapp.web.app), keeping the branding consistent for your users.

How to Add These Records

  1. Log in to your DNS provider and access your domain’s DNS settings.
  2. Add CNAME Records using the information provided above.
  3. Save Changes and wait for DNS propagation (up to 48 hours).
