NMR Email Log for CF7
Contact Form 7 sends emails silently. When delivery fails, you get no feedback — just a lost lead. NMR Email Log for CF7 records every email attempt, explains failures in plain language, and lets you switch to reliable transactional delivery in one click.
Delivery log:
Every CF7 form submission is logged — sent, failed, or pending. The log shows the form name, recipient, subject, mailer used, and timestamp. Filter by status or form to find problems fast.
Failure diagnosis:
When an email fails, the plugin captures the raw PHPMailer error and translates it to a plain-English explanation with a specific fix suggestion — not just "mail send failed."
Common diagnoses:
- Host or port unreachable → your server blocks outbound SMTP → switch to Resend
- SMTP authentication failed → wrong username/password
- Invalid recipient address → a CF7 tag is resolving to a malformed email
- PHP mail() disabled → common on shared hosting → switch to Resend
- From address rejected → sender domain not authorized to send
Resend routing (free):
Switch from unreliable server mail to Resend transactional delivery. Paste your API key, click "Send test email", done. Resend's free tier covers 3,000 emails/month — no credit card needed. All your CF7 forms use the same Resend account.
Manual retry:
Failed delivery? Hit Retry directly from the log. The plugin resends using the original rendered email body captured at send-time.
Failure alerts:
Get an email alert the moment a CF7 form fails to deliver. See the alert count for the current month in the log dashboard.
Config scanner:
Scans all CF7 forms for common mail configuration problems: missing recipient, empty body, empty subject, From address domain mismatch (a common cause of spam filtering). Issues link directly to the form editor to fix.
