LSTAR has noticed an increase in emails not being received.
Many of these are flagged as phishing due to incorrect email setup. To avoid this, ensure your emails follow best practices to improve deliverability.
Why Emails Get Flagged for Phishing
- Missing Authentication (SPF, DKIM, DMARC): Without these security measures, emails may be blocked or sent to quarantine.
- Incorrect Domain Setup: Business emails like firstname [at] businessname.com (firstname[at]businessname[dot]com) often get flagged if their domain settings aren't properly configured.
- Mismatched Sender Details: If the "From" address doesn't align with the domain’s records, the email may be marked as suspicious.
- Suspicious Links or Attachments: Shortened URLs, unexpected files, or unverified links can trigger phishing warnings.
How to Prevent Email Issues
✔ Configure SPF, DKIM, and DMARC for email authentication.
✔ Ensure domain settings match your email structure.
✔ Use professional business domains rather than free services.
✔ Avoid excessive links or attachments unless necessary.
✔ Maintain clear formatting and avoid generic, urgent wording.
