WP Mail Logging vs Mesh SMTP – Easy WordPress SMTP &

Mesh SMTP is a lightweight WordPress SMTP plugin for website owners who want a clear way to configure outgoing email without a crowded dashboard. Connect WordPress to Gmail, Google Workspace, Microsoft 365, Zoho Mail, Hostinger Email, SendGrid, Mailgun, or any custom SMTP server. The guided setup explains each field in plain language and separates mailer acceptance from real inbox delivery. Mesh SMTP works with email sent through WordPress wp_mail(), which commonly includes: Contact form notifications Password reset emails New user and administrator notifications WooCommerce transactional emails WordPress update and security notifications Messages sent by compatible themes and plugins Easy 3-Step WordPress SMTP Setup Choose your email provider from simple provider cards. Enter the SMTP connection details with clear host, security, port, authentication, username, password, and sender guidance. Send and confirm a test email so the dashboard does not claim delivery before you verify the inbox. Main Features Simple three-step SMTP setup wizard Provider presets for Gmail, Microsoft 365, Zoho, Hostinger, SendGrid, and Mailgun Custom SMTP support with optional authentication for trusted relays Test email flow with honest Accepted, Received and Confirmed, Failed, and Retest Required states Automatic test invalidation when SMTP settings change Clear SMTP host, TLS/SSL, port, authentication, username, password, From Email, and From Name fields Recommended port guidance without overwriting a custom port Saved password indicator with a dedicated Remove Saved Password action Warning when another common SMTP plugin appears active Microsoft 365 warning when OAuth or tenant SMTP AUTH policy may be required Privacy-first email logging: Off, failures only, or all mailer results Optional masked, hidden, or full recipient storage Optional subject logging and 7, 14, or 30-day retention Clear Logs and Clear Last Failure actions Masked support summary by default, with an explicit option to include personal details Safe JSON settings export and import without exporting the SMTP password wp-config.php constants for deployment-managed SMTP credentials WordPress Site Health integration Accessible provider cards, wizard steps, live status messages, and password controls Admin assets load only on the Mesh SMTP screen Capability checks, nonces, sanitization, and escaped output Honest Test Email Results A successful wp_mail() response means WordPress and PHPMailer accepted the sending request without returning an error. It does not prove that the message reached the Inbox. Mesh SMTP therefore uses a two-part verification flow: Accepted by mailer — WordPress returned no sending error. Received and confirmed — an administrator checked the Inbox or Spam folder and confirmed receipt. This avoids a misleading “delivered” message when the receiving mail server may still delay, filter, or reject the email. Privacy-First Email Logs Email logging is configurable. The recommended default stores failed emails only, masks recipient addresses, hides subject lines, and removes old entries after 14 days. Mesh SMTP never stores email bodies or attachments in its activity log. Supported Provider Presets Gmail and Google Workspace Outlook and Microsoft 365 Zoho Mail Hostinger Email SendGrid Mailgun Custom SMTP Microsoft 365 Note Some Microsoft 365 tenants do not allow username/password SMTP. OAuth 2.0 or an administrator-enabled SMTP AUTH policy may be required. Mesh SMTP currently supports standard SMTP credentials and displays a warning when the Microsoft preset is detected. Secure wp-config.php Constants Developers can define these constants in wp-config.php to override values saved in WordPress: MESHSMTP_ENABLED MESHSMTP_HOST MESHSMTP_PORT MESHSMTP_SECURE MESHSMTP_AUTH MESHSMTP_USERNAME MESHSMTP_PASSWORD MESHSMTP_FROM_EMAIL MESHSMTP_FROM_NAME The SMTP password is never shown back in the admin interface.

WP Mail Logging is the most popular plugin for logging emails sent from your WordPress site. Simply activate it and it will work immediately, no extra configuration is needed. Are your WordPress emails not being sent or delivered? Use this plugin to log all outgoing emails from your WordPress site. If there are any errors when sending the email from your site, our email logs will catch that error and display it to you. This will allow you to debug and fix your email sending issue. Did a client not receive your email? Our email logs allow you to resend any email that was sent from your site. No more lost emails! Do you just want to keep a record of all emails sent from your site? By default, WordPress and your web host do not log, store or keep track of emails sent from your website. This plugin will allow you to do just that. Our email logs will store every email that is sent from your WordPress site. You can search and view a particular email log, inspect its content or attachments, and even resend that email. What email information is logged? All emails sent from your WordPress site are logged. And here is the information that is stored: Email Subject Email Content (HTML or text) Email Attachments Email Headers (to, from, reply-to, cc, bcc, …) Error Message (in case there was an error while attempting to send the email) IP Address of originating server (can be enabled in the settings) Date and Time of the email Receiver (the TO email address) Why are my logged emails still not delivered to the inbox? There are a lot of steps that emails have to make in order to be delivered to the recipient’s inbox. When your WordPress site sends an email, there’s no guarantee it will be delivered. This is what the email’s journey looks like: WordPress creates an email WordPress passes the email to your website host and that email gets logged by our plugin The host server takes the email and sends it (SMTP or Mail Transfer Agent) Recipient server receives or blocks the email If the email is accepted, the spam filter decides if it goes to the inbox or the spam folder Recipients see the email and might open it. This plugin does not track delivery after step 2. If you have deliverability issues, we suggest installing the WP Mail SMTP plugin. WP Mail SMTP fixes WordPress email deliverability problems, you can choose between 12 email providers (Gmail, Outlook, SendLayer, Mailgun, …) to resolve your email sending issue and it’s super easy to set up. WP Mail SMTP is trusted by more than 3 million websites. Credits The plugin was created and launched in 2014 by Christian Zöller.
