By default WordPress sends email with PHP Lynbro SMTP<\/strong> sends every WordPress email through a real, authenticated SMTP\nserver \u2014 your host's, your mailbox's, or a sending service such as Brevo, SendGrid,\nMailgun, Amazon SES or Postmark. And when something goes wrong, you find out, and\nthe email is not lost.<\/p>\n\n Everything is in this free plugin. There is no Pro version, no nag screens, no\n\"upgrade\" buttons, no weekly emails from us and no other plugins installed behind\nyour back.<\/p>\n\n The well-known SMTP plugins either sell the email log, resend, backup connection and alerts as a paid\nadd-on, or give them away with a large interface built around API mailers and OAuth apps. Lynbro SMTP\nMailer does one thing \u2014 plain, authenticated SMTP \u2014 and adds what those leave out:<\/p>\n\n Lynbro SMTP connects to no service run by Lynbro<\/strong>. It connects only to:<\/p>\n\n Test emails and alerts are sent only when you or a failure trigger them. The plugin\nalso reads public DNS records (SPF, DMARC) of your sender domain through your\nserver's normal DNS resolver when you open the Test tab.<\/p>\n\n WordPress.org plugin directory (the shared Lynbro \"Our plugins\" screen).<\/strong>\nApart from the above, one request goes to WordPress.org, from every Lynbro plugin\nalike: when an administrator who may install plugins opens Lynbro \u2192 Our plugins,\nthe screen asks the WordPress.org Plugin Directory API\n(https:\/\/api.wordpress.org\/plugins\/info\/1.2\/) which Lynbro plugins are listed,\nthrough WordPress core's own The email log is stored in your own database (table Switching from another SMTP plugin? Use Import settings from \u2026<\/strong> on the Settings tab, enter the password once, then deactivate the old plugin.<\/p>\n\n\n Your host's mail server or your own mailbox works for small sites. For shops and\nanything with more than a few dozen emails a day, a sending service (Brevo,\nMailgun EU, Amazon SES, Postmark, SendGrid) delivers better. All of them work with\nplain SMTP.<\/p><\/dd>\n Both need an app password, not your normal password, when two-step sign-in is on.\nMicrosoft 365 also needs \"Authenticated SMTP\" enabled for the mailbox, and\nMicrosoft is retiring password sign-in for SMTP \u2014 if it is switched off for your\ntenant, use a sending service instead. The Test tab tells you which of these it is.<\/p><\/dd>\n No. OAuth needs an app verified by Google or Microsoft, which is the most common\nsource of breakage in other SMTP plugins. App passwords and SMTP relays do the\nsame job without it.<\/p><\/dd>\n It is encrypted with libsodium using your site's secret keys, never shown again,\nnever written to the log and left out of the settings export. For the strongest\nsetup, define it as With a backup connection set, the email goes through the backup in the same\nrequest. Without one, it is logged as failed with its content kept, an alert goes\nout if you set one up, and you can resend it from the log when the server is back.<\/p><\/dd>\n Run Check ports<\/strong> on the Test tab. Many sending services also listen on 2525.\nOtherwise ask your host to open the port.<\/p><\/dd>\n Yes. Choose Test mode<\/strong> to send every email to your own address (Cc and Bcc are\nremoved), or Do not send any email<\/strong> to only log them.<\/p><\/dd>\n Yes. Lynbro SMTP works through Yes: two plugins configuring the same email fight over it. Lynbro SMTP lists the\nother mail plugins it finds; deactivate them after importing their settings.<\/p><\/dd>\n No, and there will not be one with locked features. Lynbro makes several free\nplugins; paid services, if any, live on our website and are never required.<\/p><\/dd>\n\n<\/dl>\n\n\nmail()<\/code>, which Gmail, Outlook and most\ninboxes treat as suspicious. Password resets, WooCommerce orders and contact-form\nmessages end up in spam, or never arrive at all.<\/p>\n\nWhy another SMTP plugin?<\/h4>\n\n

What you get<\/h4>\n\n
\n
mail()<\/code>, in the same request. The visitor never sees an error.<\/li>\nmail()<\/code>, because your SMTP server may be what is down) and\/or a webhook (Slack and Discord incoming webhooks, or your own endpoint: JSON with text<\/code> and content<\/code>). At most one per hour.<\/li>\nLYNBRO_SMTP_HOST<\/code>, LYNBRO_SMTP_USER<\/code>, LYNBRO_SMTP_PASS<\/code> and friends to keep the login out of the database. Otherwise the password is encrypted with your site's keys.<\/li>\nwp lynbro-smtp test<\/code>, log<\/code>, resend<\/code>, purge<\/code>, status<\/code>.<\/li>\nPrivate by default<\/h4>\n\n
\n
External Services<\/h3>\n\n
\n
plugins_api()<\/code> \u2014 the same call the Plugins \u2192 Add New\nscreen makes.<\/p>\n\n\n
Privacy<\/h3>\n\n
{prefix}lynbro_smtp_log<\/code>):\ndate, recipients, Cc, Bcc, Reply-To, subject, headers, status, connection, error\nand \u2014 only for failed emails by default \u2014 the message content.

Which SMTP provider should I use?<\/h3><\/dt>\n
Gmail or Microsoft 365 says the password is wrong<\/h3><\/dt>\n
Does Lynbro SMTP support Gmail or Microsoft OAuth (\"Sign in with Google\")?<\/h3><\/dt>\n
Is my SMTP password safe?<\/h3><\/dt>\n
LYNBRO_SMTP_PASS<\/code> in wp-config.php<\/code> \u2014 then it is not in the\ndatabase at all.<\/p><\/dd>\nWhat happens when my SMTP server is down?<\/h3><\/dt>\n
My host blocks port 587 \/ 465<\/h3><\/dt>\n
Can I use it on a staging copy without emailing real customers?<\/h3><\/dt>\n
Does it work with WooCommerce and form plugins?<\/h3><\/dt>\n
wp_mail()<\/code>, which WooCommerce, Contact Form 7,\nWPForms, Gravity Forms, Fluent Forms and almost every other plugin use. Plugins\nwith their own built-in SMTP client (some booking plugins) bypass wp_mail()<\/code> and\nneed their own settings.<\/p><\/dd>\nAnother SMTP plugin is active \u2014 is that a problem?<\/h3><\/dt>\n
Is there a paid version?<\/h3><\/dt>\n
