Nitrosend is a bet to move the email martech layer out of standalone dashboards…

Brief

Nitrosend is a bet to move the email martech layer out of standalone dashboards and into LLM agents (Codex, Claude, ChatGPT) using one MCP install. The product is backed by the Hartley brothers — George Hartley highlights SmartrMail’s history (billions of emails; sold in 2022) and frames Nitrosend as removing the dashboard bottleneck (tweeted 2026-06-17).

Source evidence

Email is one of the last martech layers still stuck in its own dashboard while the rest of the stack moved into the agent.

Nitrosend is a bet that it doesn't have to be: one MCP install and the whole email layer runs from inside Codex, Claude, or ChatGPT. The signal worth noting is the team behind it, the Hartley brothers, who built SmartrMail into a platform that sent billions of emails before selling it in 2022.

Email dashboards had a good run.

Two decades. Billions of emails. I built two companies on them.

But the dashboard was never the product, it was the bottleneck.

We removed it. This is Nitrosend.
