Email, forms and notifications · by SuprStack Inc

SuprSend

A notification API and dashboard: your backend triggers one workflow and SuprSend sends it over email, SMS, push, Slack, WhatsApp or an in-app inbox through the providers you connect, with templates, batching/digests, user preferences, multi-tenant branding, a CLI and a hosted MCP server.

You stop hand-building channel routing, templates, digests and unsubscribe preferences for every notification, and product people can change the flows without a code deploy.
