Permanent Fix for WordPress Contact Form Email Alerts

I’m managing a WordPress-based web portal, and we’re experiencing recurring issues with our contact form email notifications. The form is built using Contact Form 7 (admin.php?page=wpcf7), and while a freelancer previously configured SMTP to resolve the issue, the fix only lasted about 14 days before emails stopped sending again.
I’m looking for a reliable, long-term solution to ensure that email alerts from our contact forms are consistently delivered. This may involve:
- Diagnosing the root cause of the SMTP failure
- Reviewing current SMTP plugin settings and authentication
- Checking for conflicts with other plugins or server configurations
- Implementing fallback or error logging to monitor future issues
- Ensuring compatibility with our hosting environment and email provider
Goal:
Restore and stabilize email functionality for Contact Form 7 so that alerts are sent reliably without manual intervention.
Deliverables:
- Working email alerts from contact forms
- Documentation of changes made
- Recommendations for ongoing monitoring or maintenance
