If you’re unhappy with OneSignal for transactional notifications, the best alternative depends on what’s bothering you most: deliverability, pricing, API reliability, inbox placement, ease of use, or support.
Common alternatives for transactional notifications/email:
- SendGrid — strong API, widely used, good for transactional email
- Postmark — excellent deliverability and focus on transactional email
- Mailgun — flexible APIs, good for developers
- Amazon SES — very low cost, more setup/ops effort
- Resend — modern developer experience, simple API
- Twilio Notify / Firebase Cloud Messaging — if you mean push notifications rather than email
- Pusher Beams — push notifications for web/mobile
- Airship — more enterprise-grade notification platform
If you want, I can help you pick the best replacement based on:
- email vs push vs SMS
- monthly volume
- budget
- need for templates/dashboard vs API-only
- regions/compliance needs
If you tell me what you dislike about OneSignal, I can recommend the closest better fit.
