How to Authenticate Your Domain Name on GoDaddy

Sending newsletters and automations from systeme.io requires an authenticated domain. That means adding DNS records at your registrar so SPF, DKIM, and related checks pass. If your domain lives at GoDaddy, this guide walks through the exact flow from the official help article (3933).

Email authentication is separate from connecting a custom funnel domain (www + SSL CNAMEs). Here we only cover Settings → Emails.

• A systeme.io account.
• Domain registered or DNS managed in GoDaddy.
• Access to GoDaddy DNS Records for that domain.
• Domain entered without www (for example sio-team.live).
• Per platform rules, the domain should have an active site linked when authenticating for email—see general domain authentication.

1. Log in to systeme.io.
2. Open Settings → Emails (or Domains under email sending).
3. Click the link to authenticate your domain and show information in email headers.
4. Enter your domain name without www and click Save.
5. Status shows Pending until DNS is correct.
6. Refresh if needed, then click the eye icon under DNS settings to reveal three CNAME records and one TXT record.

Keep this panel open—you will copy each Name/Host and Value into GoDaddy one by one.

1. Log in at GoDaddy.
2. Go to My Products → Domains and select the domain to authenticate.
3. Open DNS or DNS Records.
4. Click Add New Record.

For each of the three CNAME lines from systeme.io:

1. Click Add New Record.
2. Type: CNAME.
3. Name: paste from systeme.io but enter only the part before your domain.
   • Example: if systeme.io shows si942517.sio-team.live, enter si942517 only.
   • For DKIM-style hosts, use the full prefix shown (for example systemeio1._domainkey)—copy exactly what the eye icon displays for the host column.
4. Value: paste the target from systeme.io. Official GoDaddy guidance for systeme.io often recommends appending a period (.) at the end of the value if GoDaddy accepts it (for example inbound.systeme.io.).
5. TTL: default (often 1 hour).
6. Click Save.

Typical patterns (your values will differ per account):

• Return-path / inbound host → inbound.systeme.io
• DKIM selector → key1.systeme.io (or values shown in your panel)

1. Add New Record → Type: TXT.
2. Name: use the host systeme.io provides (often @ for root SPF-related TXT, or a specific prefix—match the eye icon).
3. Value: paste the full TXT string from systeme.io without altering characters.
4. Save.

If GoDaddy reports RECORD DATA IS INVALID, check for extra quotes, line breaks, or a truncated SPF string. Paste as one continuous value.

For stronger deliverability, add a DMARC TXT in GoDaddy (not always generated in the same popup):

• Type: TXT
• Name: _dmarc
• Value: for example v=DMARC1; p=none; rua=mailto:you@yourdomain.com

See How to Create a DMARC Record for policy details.

1. Wait for DNS propagation (often 15 minutes–48 hours).
2. Return to Settings → Emails on systeme.io.
3. Confirm status moves from Pending to Verified / authenticated.
4. Add and confirm your sender email address on the same domain if you have not already.

How many records?

Three CNAME + one TXT from systeme.io; DMARC optional but recommended.

Name field?

Prefix before your domain unless systeme.io shows a full DKIM host label.

Still Pending?

Propagation or typo—compare each field to the eye icon.

Funnel vs email?

Different settings and CNAME targets.

www in domain field?

No—use root domain only.
