Mastering Email Deliverability: Stop Landing in Spam

You can craft the perfect email but it means nothing if it lands in spam. Here is everything you need to keep your emails in the inbox.

Authentication Basics

  • SPF — Tells receiving servers which IPs can send mail for you
  • DKIM — Cryptographic signature to verify email integrity
  • DMARC — Policy for handling SPF/DKIM failures
  • TrueValue configures all three automatically when you verify your domain

Content Best Practices

  • Balance text-to-image ratio
  • Include plain-text version alongside HTML
  • Personalize subject lines without spammy trigger words
  • Make unsubscribe links visible and functional
