What does this DMARC generator analyze?

Build a complete DMARC record and get a clean, valid configuration for your domain, policy, and reporting setup.

DMARC record creation

Generate a ready-to-use DMARC TXT record.

Policy configuration

Define enforcement level (none, quarantine, reject).

Reporting setup

Add aggregate (rua) and forensic (ruf) reporting emails.

Alignment configuration

Set SPF and DKIM alignment modes (strict or relaxed).

Percentage control

Apply policy gradually using pct values.

Syntax validation

Ensure correct DMARC format and avoid errors.

DMARC Record Examples

Here are common DMARC configurations used across different enforcement levels.

1

Monitoring (no enforcement)

v=DMARC1; p=none; rua=mailto:dmarc@example.com

2

Quarantine policy

v=DMARC1; p=quarantine; pct=100; rua=mailto:dmarc@example.com

3

Reject policy

v=DMARC1; p=reject; rua=mailto:dmarc@example.com

4

With forensic reports

v=DMARC1; p=quarantine; rua=mailto:dmarc@example.com; ruf=mailto:forensic@example.com

5

Strict alignment

v=DMARC1; p=reject; adkim=s; aspf=s; rua=mailto:dmarc@example.com

6

Gradual rollout

v=DMARC1; p=quarantine; pct=50; rua=mailto:dmarc@example.com

How DMARC Works and Why It Matters

DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email authentication protocol built on SPF and DKIM.

It allows domain owners to define how receiving servers should handle emails that fail authentication checks.

A correct DMARC setup protects your domain and improves trust with mailbox providers.

DMARC process includes:

Email is sent - SPF and DKIM are validated - Alignment is checked - DMARC policy is applied

Example:

v=DMARC1; p=none; rua=mailto:dmarc@example.com

Common DMARC Errors This Tool Prevents

No DMARC record

Domain has no protection.

Policy set to none

No enforcement applied.

Missing reporting

No visibility into authentication results.

SPF/DKIM misalignment

DMARC fails even if SPF or DKIM pass.

Invalid syntax

Incorrect formatting breaks validation.

Weak enforcement

Policy not strong enough to protect domain.

Free DMARC Generator to Create a Valid DMARC Record

Use this DMARC generator to create a DMARC record for your domain, define your policy, and improve email authentication.

DMARC is a DNS TXT record that tells receiving servers how to handle emails that fail SPF or DKIM checks. If your DMARC record is missing or misconfigured, your domain is vulnerable to spoofing and your emails may be less trusted.

This tool helps you generate a valid DMARC record, configure policies, and enable reporting.

DMARC Basics

What is DMARC?
DMARC is an email authentication protocol that protects your domain from spoofing and phishing by enforcing SPF and DKIM validation.
Where is DMARC stored?
DMARC is stored in DNS as a TXT record under _dmarc.yourdomain.com.

DMARC Generator

How do I create a DMARC record?
Use a DMARC generator and publish the record in DNS.
What is a DMARC generator?
A tool that automatically creates valid DMARC records.

DMARC Policy

What does p=none mean?
Monitoring only, no enforcement applied.
What does p=quarantine mean?
Suspicious emails are sent to spam.
What does p=reject mean?
Unauthorized emails are blocked completely.

Alignment

What is DMARC alignment?
SPF or DKIM must match the sending domain for DMARC to pass.
Why does DMARC fail?
Due to SPF/DKIM misalignment or missing authentication.

Reporting

What is rua?
Aggregate reports showing authentication results across emails.
What is ruf?
Forensic reports providing details on failed messages.

Deliverability

Does DMARC improve deliverability?
Yes. It increases trust and helps emails reach the inbox.
Is DMARC required?
Strongly recommended, especially for bulk senders.

Setup

How do I create a DMARC record?
Generate a DMARC policy and publish it in your DNS.
Should I use reject policy?
Yes, but only after validating SPF, DKIM, and monitoring results.
How long does DMARC take to work?
Usually a few minutes to 48 hours after DNS propagation.
