When should you choose Sequenzy?
Sequenzy is the right choice for email:
SaaS founders who need transactional + marketing email with Stripe integration
Firebase app developers who need to add email to their app
Teams wanting marketing automation (campaigns, sequences, drip emails)
Companies needing subscriber management with lists, segments, and tags
Developers wanting a simple email API alongside their Firebase backend
When should you stick with Firebase?
Firebase is the right choice for app infrastructure:
Mobile and web app developers needing auth, database, and hosting
Teams wanting free push notifications via Firebase Cloud Messaging
Apps needing real-time database (Firestore or Realtime Database)
Projects wanting Google's infrastructure for scalability
Teams already in the Google Cloud ecosystem
They're complementary, not competing
Firebase and Sequenzy solve different problems. Most SaaS apps use Firebase (or similar) for app infrastructure and Sequenzy for email. A typical setup:
Firebase Auth for user authentication
Firestore for app data
FCM for push notifications
Sequenzy for transactional email, marketing campaigns, and Stripe-triggered automation
Honest Limitations of Sequenzy
No push notifications, auth, database, or hosting
Not an app development platform
Email only—doesn't replace any Firebase service except email needs
Requires separate integration alongside Firebase
Honest Limitations of Firebase
No email sending capability whatsoever
No marketing automation or email campaigns
No subscriber management or email lists
Push notifications only—no email, SMS, or other channels
No Stripe integration for SaaS subscription workflows
