Email communication is a critical part of business, but small mistakes can make your messages look suspicious. In today’s cybersecurity landscape, even legitimate businesses can get flagged as scammers if they neglect email best practices. Here are the top five email mistakes that can damage your reputation—and how YourDMARC helps you avoid them.
1. Missing or Incorrect DMARC Records
DMARC (Domain-based Message Authentication, Reporting, and Conformance) records are essential for email security. Without a valid DMARC policy, your emails may look like phishing attempts to recipients and email providers.
Why it matters:
- Email servers use DMARC to verify if an email is legitimate.
- Missing or incorrect records allow cybercriminals to spoof your domain.
How to fix it:
- Use YourDMARC's DMARC Record Checker to verify your records.
- Set a policy to 'quarantine' or 'reject' suspicious emails to protect your brand.
Example DMARC Record:
v=DMARC1; p=reject; rua=mailto:reports@yourdomain.com; ruf=mailto:forensic@yourdomain.com; fo=1
Explanation:
- v: Version (DMARC1)
- p: Policy (reject fraudulent emails)
- rua: Email address for aggregate reports
- ruf: Email address for forensic reports
- fo: Failure reporting options
2. Inconsistent SPF and DKIM Configurations
SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) work alongside DMARC to authenticate emails.
Mistakes to avoid:
- SPF records that don’t include all authorized email servers.
- DKIM keys that aren’t rotated regularly.
How to fix it:
- Run regular checks using YourDMARC's SPF and DKIM tools.
- Update records whenever you add or remove email services.
Example SPF Record:
v=spf1 include:_spf.google.com include:_spf.yourdomain.com -all
Explanation:
- v: Version (spf1)
- include: Authorize specific mail servers
- -all: Hard fail for unauthorized sources
Example DKIM Record:
k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCB...
Explanation:
- k: Key type (RSA)
- p: Public key for DKIM signature verification
3. Overuse of Links and Attachments
Scam emails often contain excessive links and attachments, making even legitimate messages look suspicious.
How to avoid this mistake:
- Include only essential links.
- Avoid unsolicited attachments; use cloud-sharing links if needed.
- Ensure links are properly formatted and lead to reputable sites.
Example of Safe Link Formatting:
<a href="https://yourdomain.com">Visit Our Website</
4. Misleading or Generic Email Content
Content that looks unprofessional or generic can trigger spam filters and raise suspicion.
Examples of risky practices:
- Subject lines like "URGENT!!!" or "Act Now!"
- Generic greetings like "Dear Customer" instead of personalized names.
YourDMARC's tip:
- Use clear, professional language.
- Avoid words that trigger spam filters.
Example of a Well-Formatted Email:
Subject: YourDMARC - Protecting Your Domain from Email Threats Dear [First Name], We noticed some unusual activity related to your email domain.

5. Ignoring Email Reports and Alerts
DMARC provides valuable reports that help monitor email activity. Ignoring these reports can leave you blind to ongoing spoofing attempts.
Why it's crucial:
- Cybercriminals often test domains before launching large-scale attacks.
- Reports show authentication failures and potential abuse.
How YourDMARC helps:
- Our platform consolidates reports into easy-to-understand insights.
- Track issues and adjust settings proactively.
Example of a DMARC Aggregate Report:
{ "source_ip": "192.168.1.1", "count": 100, "disposition": "none", "spf": "pass", "dkim": "fail" }
Explanation:
- source_ip: IP address of the sending server
- count: Number of emails sent
- disposition: DMARC policy action
- spf/dkim: Authentication results
