The short answer
Technically yes. Sequencers, sending infrastructure and mailbox APIs all expose sending as a tool call, and this directory counts 45 entries tagged with running an email sequence. The question worth asking is not whether it can, it is what you have put between the model deciding to send and the mail leaving.
The four things to do first
- Own the sending infrastructure decision. Sending from your primary domain is how a
mistake becomes a deliverability problem for the whole company.
9 entries are tagged
provision sending infrastructure and 13 are tagged
warm up an inbox.
- Verify every address. 15 entries are tagged
verify an email is deliverable. Unverified sending at volume is the single most reliable way to
damage a domain.
- Put approval on the send tool. Approval belongs on the tool call in the client, not in
the prompt. The model is not the boundary.
- Log every send with its arguments. If you cannot reconstruct what went out on Tuesday
and why, you do not have an agent, you have an incident with a future date.

The bit nobody enjoys
Regulatory obligations do not change because software wrote the message. Consent, opt out,
identification and record keeping are yours regardless of what generated the text, and they differ
by jurisdiction. Nothing on this page is legal advice and this directory records no compliance
claims about any tool.
The safest first version
Let the agent draft, research and queue. Let a person press send. Then move the boundary one step
at a time, and only after you have read a hundred of its drafts. The chain is
draft personalized outreach into verify an email is deliverable into
run an email sequence, and the approval belongs on the last one for longer than feels
necessary.
