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](https://resend.com) 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. #### Pro Version **[NMR Email Log for CF7 Pro](https://namir.ro/downloads/nmr-email-log-for-cf7-pro/)** adds: * Multiple transactional providers: Mailgun, Brevo, Postmark, Resend * Per-form provider routing — different provider per form * Fallback provider if primary fails * Failure alerts — webhook/Slack integration * Auto-retry — automatic re-attempt 15 minutes after failure * Per-form delivery rate statistics * Flamingo retry integration — retry directly from Flamingo inbound messages * Spam score pre-check before sending #### Privacy Notices With the default configuration, this plugin: * Does not track users * Stores email log data (form ID, recipient, subject, status, error) in a custom database table on your own server * Does not send any data to external servers (unless Resend routing is enabled, in which case email is routed via resend.com per their privacy policy) * Does not use cookies ## Screenshots [⌊Mail log — paginated table showing all CF7 delivery attempts with status, form, recipient, mailer, and retry button for failed rows.⌉⌊Mail log — paginated table showing all CF7 delivery attempts with status, form, recipient, mailer, and retry button for failed rows.⌉[ Mail log — paginated table showing all CF7 delivery attempts with status, form, recipient, mailer, and retry button for failed rows.

The log, failure diagnosis, config scanner, retry, and alerts all work with default WordPress mail. Resend routing is optional but recommended on shared hosting. ### Does Resend cost money? Resend has a free tier: 3,000 emails/month, no credit card required. Sign up at resend.com and paste your API key into the plugin settings. ### Why do my CF7 emails land in spam? The most common causes are: sending From an address on a different domain than your site, using PHP mail() on shared hosting with no SPF/DKIM, or sending From a Gmail/ Yahoo address you don’t control. The config scanner flags the From domain mismatch. Switching to Resend resolves the server reputation issue. ### Is the Resend API key stored securely? Yes. The key is encrypted with AES-256-CBC using a key derived from your WordPress secret keys before being stored in the database. It is never exposed in the admin HTML. ### Can I retry a failed email with the original message body? Yes. The plugin captures the rendered email body at send-time (after CF7 substitutes all field tags) and stores it in the log. The Retry button resends the original content, not a re-rendered template. ### Does it work alongside WP Mail SMTP or other mailer plugins? Yes for logging and diagnosis. If you have WP Mail SMTP active, its SMTP configuration takes effect — the log records what actually happened. If you enable Resend routing in this plugin at the same time as WP Mail SMTP, they may conflict; use one mailer plugin at a time. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “NMR Email Log for CF7” is open source software.
