A good setup depends on whether you want one unified messaging platform or best-of-breed tools for each channel.
Best all-in-one options
If you want in-app notifications + email + SMS from one place, look at:
- Braze — strongest overall for product messaging, segmentation, journeys, and multi-channel orchestration.
- Customer.io — great for lifecycle messaging, fairly developer-friendly, good for in-app, email, SMS.
- Iterable — strong cross-channel marketing automation, good for larger teams.
- Ortto — simpler all-in-one option, good if you want easier setup.
Best if you want in-app focused
For in-app notifications specifically:
- Pendo — excellent for product tours, onboarding, and in-app guides.
- Appcues — strong no-code in-app messaging/onboarding.
- Intercom — good for in-app chat and product messaging, plus email/SMS via integrations.
Best if you want to assemble your own stack
A common stack is:
- In-app: Intercom, Pendo, Appcues, or Firebase In-App Messaging
- Email: SendGrid, Postmark, Customer.io, or Braze
- SMS: Twilio, Postscript, or MessageBird
This gives flexibility, but you’ll need more integration work.
My practical recommendation
- If you want one platform: Braze if budget allows, otherwise Customer.io.
- If you mainly need onboarding/in-app guidance: Pendo or Appcues + Twilio/SendGrid.
- If you need support chat + notifications: Intercom.
Quick decision guide
- Startup / lean team: Customer.io + Twilio + SendGrid
- Growth SaaS / serious lifecycle marketing: Braze
- Product-led onboarding: Appcues or Pendo
- Support + messaging combined: Intercom
If you want, I can also give you:

- a recommended stack based on your company size, or
- a pick based on budget and engineering effort.
