What does SMTP2GO ask me to publish?

Adding a verified sender domain means that SPF and DKIM are automatically handled by us, and use DNS records at your own domain name.

SMTP2GO makes the values for your account, so we do not print any here.

02

Where in SMTP2GO are my values shown?

To verify your domain, we provide you with three CNAME records to add to the domain's DNS settings. SPF is covered by the first CNAME record which is the subdomain used for the return-path address we set on your behalf. Note: You do not need to update your domain's existing SPF record.

In SMTP2GO, go to Sending, then Verified Senders, then Sender domains.

Copy each value from there exactly as shown, and add each record at your DNS host.

03

Will p=reject block SMTP2GO email?

It's important to note that DMARC is not handled by SMTP2GO directly and is a separate TXT record you need to add to the domain's DNS settings.

Not once SMTP2GO signs your email with your domain's DKIM key. DMARC passes when a message passes DKIM or SPF for your own domain, and the DKIM records SMTP2GO gives you are on your domain.

SMTP2GO does not set up DMARC. It is a separate TXT record you add yourself.

SMTP2GO says you do not need to change your domain's existing SPF record.

Mail sent from a single verified address, not a verified domain, is not signed with your domain's DKIM.

Before you raise your policy, read your DMARC reports and check that email from SMTP2GO passes.
