Can I have multiple SPF records on one domain?

No. A domain must only have ONE SPF TXT record. If using multiple email services, combine them inside a single `v=spf1 include:... include:... ~all` string.

Understanding Your Results

Generates copy-pasteable DNS TXT records for SPF (`v=spf1 ... ~all`), DKIM (`selector._domainkey`), and DMARC (`v=DMARC1; p=...; rua=mailto:...`).

Practical Guidance & Next Steps

Google and Yahoo mandate valid SPF, DKIM, and DMARC records for all domains sending bulk email.

What is this?

A domain networking utility that builds standard email authentication DNS TXT records.

How does it work?

1. Enter your domain name (e.g. `example.com`). 2. Select email provider (Google Workspace, M365, SendGrid, Mailgun) and DMARC policy. 3. Copy the generated SPF, DKIM, and DMARC TXT records directly into your DNS registrar.

Why use it?

Stops phishing and domain spoofing while guaranteeing your outbound emails land in the primary inbox.

Technical Scope & Calculation Limitations

Generates standard DNS TXT syntax according to RFC 7208 (SPF), RFC 6376 (DKIM), and RFC 7489 (DMARC).

Frequently Asked Questions

DMARC (Domain-based Message Authentication, Reporting, and Conformance) tells recipient mail servers what to do (monitor, quarantine, or reject) when an email fails SPF or DKIM checks.
