Configure DNS

Once you add a domain into our system,the next step is to configure MX and SPF records.

Configure MX record

You will need to set MX records of your domain to:


Example, here we have a domain called and this is how the DNS configuration looks like on cloudflare.

Another example shows how we configure DNS record for a domain on

Configure SPF record

SPF record is a TXT record with spf prefix. You will need to add a TXT record with below value:

        v=spf1 ~all

If you already had an existing SPF record, such as you already configure it to with Amazon SES or SendGrid, you just need to insert this right after `v=spf1` like this:

    v=spf1  your-existing-spf-record-go-here

As long as this string appears inside the TXT record of `v=spf1...`, we're good. Our system also helps by detecting your existings SPF record and suggest the right change.

Configure subdomain

Sometimes when your top domain is already used with a mail service like or but you would like to have some kind of email forwarding, you can use a subdomain for that purpose.

Let's walk through a use case where we want to forward email to domain so that can be forwarded to your own QA team email. You just need to follow the same steps to set MX and SPF records. However, where you leave the hostname empty or use `@` on your domain registrar, you will enter `qa` now. Take as an example, here is how the DNS looks like.
