MailSentra: Email Logging & Diagnostics

MailSentra logs WordPress email attempts and provides email statistics, weekly and monthly reports, source-based diagnostics, search and filtering, CSV export, configurable retention, and Standard, Privacy-focused, and Custom logging modes. New to MailSentra? Follow the Getting Started guide to install the plugin, configure logging, and review your first email attempt. On licensed MailSentra Pro sites, open tracking is automatic while MailSentra email logging is enabled. It adds a small image to outgoing HTML emails and records its first request. Email privacy proxies can request the image automatically, and some clients block images, so open counts are estimates rather than proof that a person read an email. Tracking does not store request IP addresses or user agents and should be disclosed in the site's privacy policy. Standard diagnostics records recipients, subject, the full email message, status, mailer, source label, call-stack details, associated WordPress user ID, and available mail error text. It does not record email headers, attachment paths/names, or request IP addresses. Custom mode lets Pro users choose which of these fields to record. MailSentra does not copy or store attached files. Logged data is stored in the site database and is not sent to an external service. Standard diagnostics is the default and stores the full email message while omitting headers, attachment paths, and request IP addresses. Privacy-focused mode omits recipient and sender details, subject, message content, headers, attachment paths, error text, IP address, user ID, and call-stack details from new logs. Custom mode lets Pro users select which of these fields to record. All modes preserve status, mailer, source label, and timestamp. Changing modes does not alter existing logs. Use Delete All Logs on the dashboard to erase all existing log history. A "Sent" status means WordPress reported the send attempt as completed without a mail exception. It does not confirm acceptance by the recipient mail server or delivery to the inbox. Check your SMTP provider or mail service for delivery and bounce status.

2.1.7
