Why WordPress Email Delivery Fails
And how Really Simple Mail fixes it
The Problem
WordPress uses PHP's mail() function by default. It's unreliable, often blocked by spam filters, and can't authenticate properly. Your emails end up in spam or never arrive.
The Solution
Really Simple Mail routes emails through professional SMTP servers. Proper authentication, SPF/DKIM signing, and reliable delivery. Your emails reach inboxes, not spam folders.
