Custom Email Domains & Resilient Delivery - Professional Email at Scale
Introducing custom email domains with a 3-tier fallback system that ensures your event emails always reach their destination. Send from your own domain while maintaining 99.9% delivery reliability through intelligent provider switching.
Professional Email Branding 📧
Transform your event communications by sending from your own domain. Instead of generic service emails, your guests receive professional communications from events@yourcompany.com or any custom address you configure.
3-Tier Fallback System 🛡️
Never lose an email again with our intelligent delivery strategy:
Tier 1: Custom Domain SendGrid
For organizations with verified custom domains, emails automatically route through SendGrid EU with your branded sender address.
Tier 2: Primary Provider
Configurable primary provider (SendGrid or Mailgun) handles standard email delivery with reliable EU-based infrastructure.
Tier 3: Automatic Fallback
If the primary provider fails, the system instantly switches to the fallback provider, ensuring delivery without user intervention.
Smart Retry Mechanism ⚡
Dual Retry Strategy:
- Webhook-Based Retry: Monitors delivery status and retries based on provider feedback
- Timeout-Based Retry: Automatically retries if no delivery confirmation received within 5 minutes
Intelligent Failure Classification:
- Permanent failures (invalid emails) → No retry
- Provider failures → Switch to different provider
- Transient issues (rate limits) → Retry with backoff
- Unknown errors → Retry to ensure delivery
