What can you build with Mailscript?

Mailscript is a Communication API. Developers commonly use communication APIs for:

sending SMS alerts and notifications
building in-app chat and messaging features
automating email sequences and transactional emails
creating voice bots and IVR systems
verifying phone numbers at signup

No authentication required. This API is open — no signup or key needed. Ideal for quick prototypes and public-facing features. Mailscript is free to use, making it a low-risk choice to experiment with.
