The Email Sender Tool
Give an agent the ability to act on its work by sending email — plain text or HTML, with CC, BCC, and reply-to — through your own SMTP, so the workflow ends with a delivered message instead of a draft, on infrastructure you control.
An agent that can’t send is only half a workflow
An agent can research, draft, and format a perfect message — but if a human still has to copy it into an email client and hit send, the automation stops one step short of done, every time.
Drafts aren’t delivery
A finished draft still needs someone to actually send it.
Manual handoff
Copying content into an email client breaks the workflow.
No rich formatting
Plain handoffs lose the HTML structure the message needs.
Ungoverned sending
Agents sending email need to do so through controlled, logged infrastructure.
From draft to delivered
Delivery
Send via your SMTP
The workflow’s final step.
The tool sends email through SMTP you control, so an agent can complete a workflow by delivering the message itself — turning a draft into a sent email without a human handoff.
- SMTP delivery
- Multiple recipients
- Subject and body
- Completes the workflow
Draft → delivered
Formatting
HTML or plain, CC and BCC
Real email, fully addressed.
Send rich HTML or plain text, with CC, BCC, and a reply-to address — everything a proper message needs, so the agent’s output reads like a real email, not a fragment.
CC · BCC · reply-to
Governance
Governed, on-premise sending
Under policy and logging.
Email goes out through your own server with audit logging on infrastructure you control, so agent-sent mail is governed and traceable rather than routed through an opaque service.
Your SMTP, logged

Assigned to agents, orchestrated as networks
On VDF AI, an industry’s use cases map to agents, and you assign tools like this one to those agents. Compose multiple agents into a governed, on-premise network.

Questions about the Email Sender tool
What does the email sender tool do?
It sends email via SMTP — plain text or HTML, with CC, BCC, and a reply-to address — so an agent can complete a workflow by delivering the message itself rather than handing a draft to a human.
Can it send HTML email?
Yes. Set the html flag to send a rich HTML message; leave it off for plain text. CC, BCC, and reply-to are all supported.
Whose mail server does it use?
Your SMTP. Email goes out through infrastructure you control with audit logging, so agent-sent mail stays governed and traceable.
Is sending governed?
Yes. It runs through a controlled tool with audit logging on infrastructure you operate, rather than routing mail through an opaque external service.
How is it used by agents?
It is the delivery step for sales, communications, and reporting agents and the final action of many networks, often paired with the document and PDF generators to attach a deliverable.
