Overview

EmailEngine can use Gmail REST API directly instead of IMAP/SMTP. This provides:

• Native Gmail features - Labels, categories, search
• Cloud Pub/Sub webhooks - Real-time notifications via Google infrastructure
• Granular OAuth2 scopes - Use limited scopes for Google verification

When to Use Gmail API

Use Gmail API when:

• You want native Gmail label and category support
• Google's verification requires limited OAuth2 scopes
• You need Cloud Pub/Sub for real-time notifications

Use IMAP/SMTP when:

• You need the full https://mail.google.com/ scope
• Your organization restricts Cloud Pub/Sub
• You're migrating existing IMAP integrations
