Without a properly configured DMARC record, your domain is vulnerable to email spoofing. Attackers can impersonate your domain, tricking recipients into trusting malicious emails. A valid DMARC record helps prevent this.
With Smartlead’s DMARC record generator, you can create a DMARC record and configure your domain for better email authentication
Ensure you send emails only through your authorized servers and reduce spoofing risks while improving deliverability.
Generate SPF Record Now
Check if DKIM records are set up correctly for your domain. Ensure your email authentication policies protect your domain.
Get DKIM RecordStart by typing your domain name (e.g., example.com) into the provided field.
Choose your preferred DMARC policy:
This is optional, but if you’d like to receive aggregated reports of your DMARC performance, enter an email address where these reports should be sent.
Select afrf (Aggregated Feedback Report Format) to standardize your report format and ensure that you receive the correct data on your email’s performance.
Decide the percentage of emails that should be subject to DMARC. Start with 100% for full enforcement or adjust based on your needs.
Set the alignment mode for SPF and DKIM:
If you’d like to receive detailed forensic reports about emails that fail DMARC checks, provide your email address to receive them.
Choose how often you want to receive DMARC reports. By default, the interval is set to 86400 seconds (1 day), which is typically sufficient for most users.
After filling in the necessary fields, click the Generate button. Smartlead will create your DMARC record, which you can then copy and add to your domain’s DNS settings.
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an essential email authentication protocol that works alongside SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to prevent email spoofing and improve email deliverability.
By publishing a DMARC record in your domain’s DNS, you enable email providers like Gmail, Yahoo, and Outlook to verify that the emails sent from your domain are legitimate.
When a DMARC policy is in place, it tells receiving mail servers how to handle emails that fail authentication checks. Depending on the policy you set, emails may either be quarantined, rejected, or simply monitored (with no action taken).
Why DMARC Matters:
Strengthens Email Security: By enforcing authentication checks, DMARC helps protect your domain from being exploited for phishing attacks, which are designed to trick recipients into disclosing sensitive information.
Improves Email Deliverability: With DMARC, inbox providers are more likely to trust your emails, reducing the chances of your messages being flagged as spam.
Protects Against Email Spoofing: DMARC ensures that only authorized senders can use your domain to send emails, helping to prevent malicious actors from impersonating your brand.

Imagine a malicious actor impersonating your brand and sending fraudulent emails to your customers. DMARC validation ensures that only authorized emails from your domain reach your audience, protecting your customers from phishing scams and maintaining their trust.
When sending high-volume marketing emails, you need to ensure they reach the inbox — not the spam folder. DMARC helps improve email deliverability, ensuring your carefully crafted campaigns aren’t blocked or flagged by inbox providers like Gmail and Outlook.
Your domain’s reputation is everything. A domain with no DMARC policy is an easy target for attackers, which can harm your brand image. By implementing DMARC and setting a strict policy, you stop unauthorized senders in their tracks, safeguarding your domain’s reputation and your email’s integrity.
You might use third-party services for sending emails (like email marketing platforms or customer support systems). With DMARC reports, you gain insight into which senders are authorized and which are not. This helps you identify unauthorized users and ensure that only trusted services are sending emails under your domain.
Emails such as order confirmations, receipts, and password resets are critical for customer experience. If these emails are marked as spam or rejected, it can cause frustration for your users. DMARC validation ensures these essential communications are delivered securely and don’t get flagged by inbox providers.
In industries like finance, healthcare, or e-commerce, email security is not just a best practice; it’s a requirement. DMARC helps you meet email authentication standards and ensures compliance with regulations that mandate secure communication, preventing any legal or reputational fallout.

A DMARC record helps protect your domain from being used in email spoofing and phishing attacks. It provides you with reports on email activities, allowing you to monitor and improve your email authentication practices.
The essential tags for a DMARC record are:
v: Version tag, which must be "DMARC1".

p: DMARC policy, which can be "none," "quarantine," or "reject".
The `p` tag specifies the DMARC policy for your domain.
The values can be:
none: Takes no action against non-authenticated emails.
quarantine: Marks failed emails as suspicious.
reject: Blocks failed emails from being delivered.
The `ri` tag determines the reporting interval in seconds. The default is 86400 seconds (once a day). However, the actual frequency may vary depending on the ISPs.
Yes, you can use the `sp` tag to set specific DMARC policies for subdomains. If the `sp` tag is not set, subdomains will inherit the main domain policy. Feel free to reach out to our customer support team for any query or concern.
DMARC policies apply to subdomains based on the sp (subdomain policy) tag. By default, subdomains inherit the main domain’s DMARC policy. To customize this, use a DMARC policy generator to specify different rules for subdomains if needed. When you build DMARC record, ensuring proper subdomain policy settings helps manage email security across all related domains.
DMARC record checks can fail due to syntax errors, incorrect policies, or misconfigured SPF/DKIM settings. Ensure your DMARC record is correctly formatted and aligns with your SPF and DKIM settings. Utilize a DMARC TXT record generator to verify and correct any issues. Properly configuring your DMARC setup using a DMARC policy generator will help resolve these failures.
DMARC itself cannot be spoofed if properly implemented, as it relies on SPF and DKIM for authentication. However, misconfigurations or weak policies can lead to gaps in protection. To prevent this, use a DMARC generator tool or DMARC record creator to accurately build DMARC records and enforce strong policies. Regular monitoring and adjustments ensure continued email security.
Simply submit your domain or subdomain in the tool.
Our DMARC Record Generator will guide you through a quick and advanced setup to create your DMARC record.
Fill in the required fields, click "Generate DMARC," and your record will be ready.
Yes, by including the `rua` and `ruf` tags in your DMARC record, you can receive aggregate and forensic reports on email activities. These reports help you understand your email flows and authentication status.
You can use the `pct` tag to specify the percentage of failed emails that the DMARC policy should apply to. For example, `pct=70` means the policy applies to 70% of failed emails.
If your DMARC record has errors or is missing required tags, it will be ignored. Ensure that the `v` tag is set to "DMARC1" and that the `p` tag is properly configured.
DMARC domain alignment ensures that the domain used in SPF and DKIM matches or aligns with the domain in the email’s From header. It can be strict or relaxed based on adkim (DKIM alignment) and aspf (SPF alignment) settings. When you generate DMARC record, these settings help ensure that only authorized emails are processed, enhancing email security.
No, you cannot effectively implement DMARC without SPF or DKIM. DMARC relies on these authentication methods to function. If you want to create a DMARC record, ensure SPF and DKIM are set up first. Use a DMARC record creator or DMARC generator tool to integrate these elements properly for complete email protection.
Yes, if misconfigured, DMARC can affect legitimate email delivery by inadvertently marking valid emails as suspicious or rejecting them. To avoid this, carefully generate DMARC record settings and test configurations. Utilise a DMARC TXT record generator to create a record that balances security with deliverability, and regularly review reports to fine-tune your settings. Proper setup with a DMARC policy generator helps minimize disruption to legitimate emails.
