SendGrail routes WordPress emails via SMTP providers with routing, real-time tracking, and automatic failover, so every email lands in the inbox.

Brighter Fox

WordPress emails landing in the spam folder, or worse, not delivering at all.
That’s the common scenario among WordPress site owners.
By default, WordPress uses the standard PHP mail function to send emails, which is notoriously unreliable and frequently blocked by major email clients.
<a href="https://sendgrail.com/" rel="nofollow ugc">SendGrail SMTP</a> solves this problem permanently and without charging you a penny. YES! SendGrail is 100% free with no paid option at all.
SendGrail completely reconfigures how your WordPress site sends out emails. By routing your outgoing messages through dedicated, trusted SMTP (Simple Mail Transfer Protocol) providers, we ensure that your password resets, WooCommerce receipts, and contact form submissions reach your users’ inboxes every single time.
Designed for both beginners and advanced users, SendGrail combines a streamlined, one-click setup with powerful enterprise-grade tools like automatic failover routing and real-time delivery logs.
