Nitrosend

It targets agencies, SaaS teams and builders who run transactional email, flows and on‑brand newsletters across one or multiple brands. The product emphasizes prompting instead of a traditional dashboard, enabling teams to create production-ready, brand-matched emails and entire automation flows via natural language and agent integrations, with human approval gates and enterprise delivery features.

Connects to Claude, ChatGPT, Codex, Cursor, Gemini and any MCP-compatible agent so you can build sequences, campaigns and automations by prompting rather than using a dashboard.

NitroWheel LLM continuous optimisation

Email performance (opens, clicks, replies) is fed back into NitroWheel LLM to continuously optimise subject lines, send times and content.

Delightfully prompted, pixel-perfect design

Generates pixel-perfect, brand-matched responsive emails from natural language descriptions using each brand's Brand Kit (colors, fonts, logo); no template editor required.

Transactional + Marketing + Multi-brand

Supports transactional emails, marketing campaigns, and automation flows across multiple brands, domains and campaigns from a single platform.

Bring‑Your‑Own sending and AI keys

Supports using existing sending providers (SendGrid, Postmark, Resend, Mailgun, SES) and your own Anthropic or OpenAI keys for AI.

Deliverability & infrastructure features

Enterprise-level reliability with 99.99% uptime, automatic DKIM/SPF/DMARC configuration, dedicated IPs, auto-warmup and SplitStreams to separate transactional and marketing traffic.

API / CLI / MCP Email integration
