Gig Central's Hybrid Mail Routing handles outbound delivery using a combination of personal SMTP integration and verified system mail gateways (AWS SES/Resend).
This guide walks you through email configuration and deliverability best practices.
1. Understanding Delivery Options
The system routes different email types using target delivery options:
- Outreach & Sales (Personal SMTP): Cold campaigns and manual pitches route through your connected inbox (Google Workspace or Outlook). This makes emails look like personal correspondence, maximizing open rates.
- System Notifications & Billing (AWS SES): Welcome alerts, portal invitations, and Stripe invoices route through verified AWS SES domains to ensure delivery.
2. Setting Up Personal Mail Integrations
- Go to Settings > Integrations > Email Accounts.
- Enter SMTP server configurations, port numbers, and login details.
- Run the Test SMTP Connection check.
- Credentials are encrypted prior to database storage. See IMAP Security for details.
3. How It Works (Behind the Scenes)
- Mail Dispatcher Routing: The dispatch worker evaluates outgoing email queues. If a personal SMTP server is connected, it routes outreach pitches through that account. If the connection fails, it routes through system SMTP fallbacks.
- Queue Retries: Outbound errors trigger automated retry queues managed in the Email Queue Processor.
4. Maximizing Deliverability
- Authenticate Custom Domains: Complete DKIM and SPF checks detailed in DNS Verification.
- Monitor Bounce Rates: Periodically review outbox logs to catch and clean up bouncing addresses.
