Nitrosend

Official

Nitrosend is AI-Native Email: a full email service provider built for the MCP era, where Claude is the interface. Connect once with OAuth and Claude can run your entire email program: no tab-switching, no drag-and-drop editor, no CSV wrangling. What Claude can do with Nitrosend: • Compose on-brand emails with a section-based designer. A composition contract feeds Claude your brand kit, voice, and design context so drafts come out on-brand, then validates them before anything persists. • Send campaigns to lists and segments, with review, test sends, and an explicit approval step before anything goes live. • Build automation flows (welcome series, cart abandonment, win-backs) from triggers, waits, splits, and webhooks. • Send transactional email: receipts, OTPs, password resets, single recipient, immediate, idempotent. • Import and manage contacts: CSV imports up to 250k rows, segments, tags, lists, and TCPA/GDPR-aware opt-in handling. • Verify sending domains, configure senders, and read deliverability-aware analytics with trends and benchmarks. Safety is built in: read-only tools are annotated as such, destructive actions prompt, sends require explicit approval, and large imports hold for review. Docs: docs.nitrosend.com
