Fix Email Going to Spam

Why Emails Go to Spam

Spam filters analyze sender reputation, authentication, and content.

Fix 1: Set Up Proper Authentication

Add these DNS records:

SPF (Sender Policy Framework)

# TXT record
yourdomain.com.  TXT  "v=spf1 ip4:YOUR_IP ~all"

DKIM (DomainKeys Identified Mail)

Generate and add DKIM key from your email server.

DMARC (Domain-based Message Authentication)

# TXT record
_dmarc.yourdomain.com.  TXT  "v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com"

Fix 2: Check IP Reputation

# Check if IP is blacklisted

If blacklisted, request removal or use SMTP relay service.

Fix 3: Use Transactional Email Service

SendGrid, Mailgun, Amazon SES, Postmark have better deliverability.

Fix 4: Warm Up New IP

If new VPS, send small volumes gradually:

• Day 1-2: 50 emails
• Day 3-4: 200 emails
• Day 5-7: 500 emails
• Week 2: 1000+ emails

Fix 5: Configure Reverse DNS (PTR)

# PTR should match your domain
dig -x YOUR_IP

Request PTR from Hostxpeed support.
