How to Fix WordPress Emails Going to Spam

Why WordPress Emails Go to Spam

WordPress uses PHP mail() function by default, which has poor deliverability. Email providers like Gmail mark these emails as spam because they lack proper authentication.

The Solution: SMTP with OAuth2

SMTP (Simple Mail Transfer Protocol) with OAuth2 authentication solves this problem. Major email providers trust OAuth2 authenticated emails.

• Mailgun: 5000 free emails/month for developers
• Amazon SES: Pay-as-you-go pricing, very affordable
