What is a DMARC record generator?
A DMARC record generator is an online tool that helps businesses create a DMARC TXT record for their domains. DMARC is an email authentication protocol that builds on Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) to protect your company’s domain from unauthorized use in email communications.
How DMARC works: A simple overview
| Protocol | Purpose | How it works |
|---|---|---|
| SPF | Defines authorized sending IP addresses for domains | Checks if the sending server’s IP address is listed |
| DKIM | Verifies message integrity with a cryptographic signature | Confirms the email content hasn’t been altered |
| DMARC | Sets a policy for handling unauthenticated messages | Instructs receiving servers on how to handle emails that fail SPF or DKIM checks |
When your organization creates a DMARC record, it has to publish a DNS entry that instructs receiving email servers on how to handle emails that fail SPF or DKIM checks. The options available are:
- p=none: Monitors suspicious activity
- p=quarantine: Quarantines suspicious emails
- p=reject: Rejects unauthorized emails
The DMARC record also includes instructions on where to send reports about email authentication activity, giving your business visibility into who’s sending emails on its behalf.
Key takeaway: DMARC can help ensure that only emails that pass SPF and DKIM checks are delivered, providing a strong defense against spoofing.
Using a DMARC record generator simplifies the implementation process. It guides your company through the required inputs and automatically produces a correctly formatted DMARC record. This reduces the risk of errors and strengthens your organization’s email security.
Why a DMARC record generator is important
Implementing DMARC is a critical step in modern email security. Using a DMARC record generator makes this process simpler and more reliable.
Key benefits
1. Protect against phishing and spoofing
Cybercriminals frequently impersonate legitimate domains to trick recipients into opening malicious emails or sharing sensitive information. Without a DMARC record, your business’s domain remains vulnerable to these cyberattacks. DMARC can help prevent them by instructing receiving email servers to reject or quarantine unauthenticated messages.
2. Improve email deliverability
Using a DMARC generator to add a record to your company’s DNS tells email providers that your domain is protected. This improves your organization’s sender reputation and helps ensure its legitimate messages are delivered to inboxes, not Spam folders.
3. Gain visibility through reporting
DMARC provides two types of reports:
- Aggregate (RUA): Summarizes email authentication results
- Failure (RUF): Provides detailed information on individual failed messages
These reports offer insights into who’s sending emails on your business’s behalf and how its messages are performing. Our DMARC record generator allows your company to specify where these reports should be sent, enabling continuous monitoring and faster response to suspicious activity.
4. Simplify complex configuration
Manually creating a DMARC record can be challenging, especially for those new to DNS configuration. The syntax must be precise, and policies must be carefully selected to avoid disrupting legitimate email delivery. A DMARC creator tool like ours can guide your organization through generating a valid and effective record.

Verifying the DMARC record generator results
Verifying your company’s DMARC record is essential. To ensure the configuration and functionality:
- Use a DMARC checker: Tools like Sendmarc’s DMARC record checker confirm that a record is live and properly formatted.
- Monitor DMARC reports: Review reports sent to the specified addresses to track email authentication results and detect any unauthorized senders.
- Adjust the policy gradually: Begin with a policy of p=none to monitor activity without affecting delivery. Once confident, update your organization’s policy to p=quarantine and finally to p=reject for full protection.
Take control of your business’s email security
Leaving your company’s domain unprotected exposes it to phishing and spoofing risks. Sendmarc’s DMARC record generator makes it easy to:
- Create a valid DMARC record in minutes
- Improve your domain’s email deliverability
- Strengthen your organization’s email security posture
