Is your WordPress site silently failing to send emails?<\/strong> Order confirmations, password resets, contact form notifications, shipping updates \u2014 when they don't land in the inbox, you're usually the last person to find out, often from an angry customer. SMTP Manager \u2013 Email Logs, Monitoring & Alerts is the WordPress SMTP plugin that fixes email deliverability at the source, logs every single send, and alerts your team the instant delivery breaks again \u2014 on Slack, Microsoft Teams, Google Chat, or Discord, completely free.<\/p>\n\n Most WordPress SMTP plugins stop the moment your email starts sending again. This one keeps going: continuous SMTP health monitoring, a fully searchable email log with CSV export, scheduled delivery reports, and real-time failure alerts that many competing SMTP plugins lock behind a paid upgrade.<\/p>\n\n By default, WordPress sends email through your server's PHP The plugin reconfigures This is the feature most SMTP plugins put behind a premium plan. Here, it's free:<\/p>\n\n WooCommerce, Contact Form 7, WPForms, Gravity Forms, Elementor Forms, user registration\/password reset emails, and literally any other plugin or theme that sends mail through WordPress's standard Anything that speaks standard SMTP with host\/port\/username\/password authentication works, because the plugin talks SMTP directly rather than locking you into a specific provider's proprietary API:<\/p>\n\n Most SMTP plugins solve half the problem: they get your email sending again, and stop there. If the connection breaks again next month \u2014 expired app password, host changed something, provider outage \u2014 you won't know until someone tells you. Many plugins in this category also reserve email alerting (Slack, Teams, Discord notifications) for their paid tier. SMTP Manager \u2013 Email Logs, Monitoring & Alerts treats failure alerting as core functionality, not an upsell, because a delivery plugin that can't tell you when delivery breaks isn't finished doing its job.<\/p>\n\n Full plugin details: bytecorestack.com\/plugins\/smtp-manager<\/a>. For SMTP protocol background, see the WordPress wp_mail() developer reference<\/a>.<\/p>\n\n This plugin may contact the following external services. All connections are either user-initiated or require explicit configuration by the site administrator.<\/p>\n\n 1. Your SMTP server (user-configured)<\/strong>\nThe plugin routes all WordPress emails through the SMTP server credentials you enter in Settings \u2192 SMTP Manager. The hostname, port, username, and password are provided entirely by you. No data is sent to any ByteCore Stack server.<\/p>\n\n 2. Slack Incoming Webhooks (optional)<\/strong>\nIf you enable Slack alerts, the plugin will POST a JSON failure notification to the Slack Incoming Webhook URL you provide when consecutive SMTP failures are detected.

This URL is entirely user-supplied \u2014 point it at Zapier, Make, n8n, or your own server. No data is sent unless you configure this channel.<\/p>\n\n 7.

Use your Microsoft 365 account password or an app password. Set the host to Yes.

mail()<\/code> function. PHP mail has no authentication \u2014 no SPF, no DKIM, nothing that proves to Gmail, Outlook, or Yahoo that the message is legitimate. Most inbox providers either bin it as spam or drop it outright. That's why \"WordPress not sending email\" is one of the most common WordPress problems there is, and why every serious site needs proper SMTP \u2014 authenticated, encrypted mail delivery through a real mail server or transactional email provider.<\/p>\n\nHow SMTP Manager fixes it<\/h4>\n\n

Every email is logged with its delivery status, and an automated health check keeps testing your connection in the background \u2014 so instead of finding out about a broken mail server from an angry customer, you find out from a Slack message.<\/p>\n\n\u2705 Core features<\/h4>\n\n
