Workflow email sending is limited to a single built-in provider, preventing users from leveraging their existing SMTP infrastructure or preferred email services. This hinders adoption for teams needing to send emails from their own domain.
### Feature request ### Feature request # Custom SMTP Provider Support for Workflow Email Sends Feedback: https://posthog.com/questions/custom-smtp-support ## Problem Currently, workflow email sending only supports a single built-in email provider. Users who have existing email infrastructure (e.g. their own SMTP server or a preferred email service) cannot use it for workflow email sends. This blocks adoption for teams that want to send workflow emails from their own domain/provider for compliance, deliverability, or branding reasons. ## Proposed Solution Allow users to configure a custom SMTP server as an email provider for workflows. This would involve: 1. Adding SMTP as a supported provider in the email integration setup 2. Allowing users to configure SMTP host, port, credentials, and TLS settings 3. Domain verification flow for custom SMTP providers ## Why this matters - Unblocks users who want to migrate their workflows to PostHog but need custom email infrastructure -
