About SMTP
SMTP is an email delivery protocol focused on ensuring messages reach recipients promptly and reliably. It helps users avoid common issues like spam filters and blacklists, improving overall deliverability. Sending WordPress emails through an SMTP server helps to prevent outgoing emails being marked as spam.
When used with WPForms and WP Mail SMTP, any SMTP provider can be used to improve email deliverability for form notifications. WP Mail SMTP reconfigures WordPress to use a proper SMTP provider for sending emails, which can significantly improve delivery rates. This setup helps ensure that critical emails from your forms, such as user registrations or customer inquiries, have a higher chance of reaching the intended inbox. The integration allows for features like email logging and resending failed emails, giving you more control over your form-related communications.
