In the future all the agent communication will be using agentmail!

Don't know about all but certainly a significant proportion!

Cool launch. Assuming you guys view email (and therefore SMTP) as becoming the de facto agent communication protocol in the long run. My question — why not something bespoke, similar to OpenAI’s Agentic Commerce Protocol or x402 from Coinbase?

Very interesting. I have a lot of enterprise AI use cases that would really benefit from being email native.

We’re an O365 GCC shop. Appreciate that your enterprise options include Bring Your Own Cloud, that makes things much easier for us.

It would be nice to have integrations with n8n and Glean.

Network effects - agents need to meet humans where they already work. Would rather use something standard than bespoke.

amazing now do the same for voice and sms!

We have gotten a lot of requests for SMS. Seems like a natural next step.

Good luck getting this past A2P campaign registration rules...

> Agents that source quotes, negotiate prices, and get the best deals.

Didn't Alexa fail miserably with the "have AI buy something for me" theory?

There is a significant mental in allowing someone else make purchase decisions on my behalf:

- With a human, there is accountability.

- With deterministic software, there is reproducibility.

With an agent, you get neither.

FWIW - I am not anti-LLM. I work with them and build them full time.
