Gmail and Yahoo enforced strict 2024 sender rules for domains sending over 5,000 emails/day. What exact DNS records and HTTP headers are required to stay compliant?
Summary of 2024 Gmail & Yahoo Enforcement Rules
As of February 2024, sending over 5,000 emails per day to Gmail or Yahoo addresses requires strict technical compliance. Failing any requirement results in immediate soft bounces or global domain blocklisting.
Mandatory Compliance Checklist:
1. Technical Authentication (100% Alignment)
- SPF: Valid TXT record published (
v=spf1 include:amazonses.com ~all). - DKIM: Custom domain signing (
autosend._domainkey.yourdomain.com). - DMARC: Published DMARC record (
v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com). - Forward & Reverse DNS: Matching PTR records for custom dedicated IPs.
2. One-Click Unsubscribe Headers (RFC 8058)
Marketing and bulk promotional emails MUST include List-Unsubscribe and List-Unsubscribe-Post headers:
List-Unsubscribe: <https://api.autosend.com/v1/unsubscribe/token_123>, <mailto:unsubscribe@yourdomain.com>
List-Unsubscribe-Post: List-Unsubscribe=One-Click
3. Strict Spam Rate Thresholds
Keep user spam complaint rates in Google Postmaster Tools strictly below 0.10% (1 in 1,000). A complaint rate exceeding 0.30% results in immediate domain suppression by Google filter engines.
