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.
