When to Use Each
Use BlueBubbles if you want to access your personal iMessages from an Android phone or non-Apple device. BlueBubbles is an excellent open-source project for personal use — it lets you run a server on your Mac that bridges iMessage to other platforms. It's free, community-maintained, and works well for individual use.
Use Sendblue if you need to send iMessages programmatically for business purposes: sales outreach, customer support, notifications, AI agents, CRM integrations, or any use case that requires an API, multiple phone numbers, compliance, and reliability.
These are fundamentally different products for different use cases. BlueBubbles is a self-hosted bridge for personal messaging. Sendblue is managed infrastructure for business messaging at scale.
Business Requirements
If you're building a product or running a business that needs iMessage capability, here's what matters:
- Reliability: Sendblue's infrastructure is monitored 24/7 with redundancy and failover. A self-hosted Mac in your closet is a single point of failure.
- Scale: Sendblue supports thousands of messages per day across multiple phone numbers. BlueBubbles is limited to one Mac and one Apple ID.
- Compliance: Sendblue is SOC 2 compliant and supports HIPAA. Self-hosted solutions have no compliance certifications.
- Integrations: Sendblue has native CRM integrations, webhooks, SDKs in 6 languages, and an MCP server. BlueBubbles has a REST API but no business integrations.
- Support: Sendblue offers dedicated support and onboarding. BlueBubbles is community-supported.

Is BlueBubbles free?
Yes, BlueBubbles is free and open-source. However, you need to provide your own Mac hardware (always-on) to run the server. For personal iMessage access from Android, it's a great free option.
Can BlueBubbles be used for business messaging?
BlueBubbles is designed for personal use, not business messaging. It lacks compliance certifications (SOC 2, HIPAA), CRM integrations, multiple phone numbers, and the reliability guarantees businesses need. For business iMessage, use a managed provider like Sendblue.
Do I need a Mac for Sendblue?
No. Sendblue is a cloud-hosted API — you don't need any Apple hardware. Sign up, get API keys, and start sending iMessages from any platform. Sendblue manages all the Apple infrastructure on your behalf.
