Overview

A contact form may appear to work while silently failing to deliver submissions to the business mailbox.

Symptoms

• Users report inconsistent or failed access to the affected service, device, or application.
• Normal business or home workflows are interrupted, delayed, or no longer reliable.
• The issue may be isolated to one user or may affect multiple systems depending on the root cause.

Cause

SMTP misconfiguration, captcha issues, plugin conflicts, spam filtering, or mailbox routing problems frequently cause this issue.

Resolution

Test the form end to end, review form plugin settings, confirm SMTP authentication, inspect spam or quarantine destinations, and verify the receiving mailbox is valid.

1. Confirm the exact symptoms and identify who or what is affected.
2. Check for recent changes such as updates, password changes, hardware swaps, DNS changes, or policy adjustments.
3. Test the most likely root cause first and document all findings clearly.
4. Apply the corrective action in the least disruptive way possible and verify the issue is fully resolved.
5. Record the final outcome, any user communication, and any recommended follow-up work.

Prevention

Use authenticated mail sending, monitor form delivery, and test forms after website updates.

When to Contact Support

If the issue continues after standard troubleshooting, affects multiple users, involves data loss risk, or raises security concerns, it should be escalated to a qualified technician promptly.
