Product Area: Email (LC Email / Custom SMTP) Priority: High (Deliverability & Compliance) Use Case: High-volume transactional and broadcast email using Amazon SES Summary When using LC Email with Mailgun, GoHighLevel correctly includes RFC-compliant List-Unsubscribe headers. However, when using Amazon SES as a custom SMTP provider, these headers are not included, which creates deliverability and compliance issues for bulk senders. This makes Amazon SES impractical for production email sending despite being a supported SMTP option. Current Behavior LC Email (Mailgun integration) Sends: || List-Unsubscribe: <mailto:...>, <https://...> || List-Unsubscribe-Post: List-Unsubscribe=One-Click -> Gmail/Yahoo display native “Unsubscribe” UI -> Complies with Google/Yahoo 2024 bulk sender requirements Custom SMTP (Amazon SES): -> No List-Unsubscribe headers are sent -> Gmail does NOT show native unsubscribe -> Unsubscribes rely solely on footer links -> Increases spam complaints and suppresses inbox placement -> Fails Google/Yahoo bulk sender expectations Why This Matters (Deliverability Impact) As of 2024, Gmail and Yahoo require bulk senders to: • Support one-click unsubscribe • Include List-Unsubscribe and List-Unsubscribe-Post headers • Provide frictionless opt-out without login or extra steps Without these headers: • Inbox placement is negatively impacted • Complaint rates increase • Sender reputation degrades over time • High-volume senders cannot safely use SES via GHL This affects: • Agencies • Newsletter businesses • Daily senders • High-volume broadcast workflows Requested Enhancement When using custom SMTP providers (Amazon SES), please: Inject RFC-compliant headers into all outbound emails: || List-Unsubscribe: < mailto:unsubscribe@domain.com >, || < https://yourdomain.com/unsubscribe?token= ...> || List-Unsubscribe-Post: List-Unsubscribe=One-Click Allow the unsubscribe URL to: • Respect existing GHL unsubscribe logic • Mark contacts as unsubscribed immediately • Work without authentication Apply this consistently across: • Broadcasts • Automations • Campaign emails This should mirror existing behavior in the Mailgun (LC Email) integration. Additional Context -> Amazon SES fully supports List-Unsubscribe headers -> This feature works correctly today in many ESPs (FluentCRM, Email Octopus, Mail Mint, Sure Contacts etc...) It's already possible to handle bounces via Make.com + SES event notifications. This change would make SES viable as a long-term sending option inside GHL Business Impact for GoHighLevel Adding this feature would: -> Reduce LC Email cost objections for high-volume senders -> Improve deliverability outcomes platform-wide -> Reduce spam complaints and support tickets -> Enable agencies to use SES at scale without compromising compliance -> Align GHL with modern bulk sender standards Closing This is not a workaround request — it’s a core deliverability requirement for custom SMTP usage in 2024+. Parity with the Mailgun integration would unlock SES as a first-class sending option inside GoHighLevel. Thank you for considering this.
