Best Smtp WordPress Plugins

SMTP plugins replace WordPress's default mail function — which relies on the server's local sendmail and is frequently blocked or flagged as spam — with authenticated email delivery through a dedicated mail provider. By routing transactional email through services like SendGrid, Mailgun, Postmark, or Gmail SMTP, these plugins ensure that password resets, order confirmations, and contact form notifications actually reach the inbox rather than landing in spam folders. WP Mail SMTP is the most widely installed solution in this category and supports virtually every major mail provider. Any WordPress site that sends emails to users should configure an SMTP plugin as a baseline reliability measure.
