Elastic Email for AI agents

Elastic Email is a transactional and marketing email platform with contact management, campaigns, and delivery reporting, used by businesses that send both automated and promotional email. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

What agents do in Elastic Email.

01

Check campaign delivery stats

Get a campaign's report to see delivery, open, and bounce rates after a send.

02

Add contacts to a list

Add new contacts to a contact list once they opt in through a signup form.

03

Confirm before deleting a domain

Require approval before deleting a sending domain, since it can break every campaign using it.

02 · ACTIONS

91 Elastic Email actions, graded by risk.

Every Elastic Email action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

  1. 01Your users connect Elastic EmailThey add their Elastic Email api key on Arc0 Connect, under your brand. It goes straight into the vault.
  2. 02You set the rulesReads run, writes like “create Domain” can wait for the user, and “delete File” can be denied outright.
  3. 03Any agent can actYour agent calls Elastic Email through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
POLICY.TS
await arc0.policies.set('elastic_email', {
  read: 'allow',
  write: 'ask',        // create_domain
  destructive: 'deny',  // delete_file
})

# Claude Code: the same connection, one URL

04 · AUTH AND DATA

How Elastic Email connects.

Users add their Elastic Email api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same Elastic Email connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Elastic Email and Arc0, answered.

Q01

Can I use Elastic Email with Claude, ChatGPT or Cursor?

Yes. Connect Elastic Email to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Elastic Email actions you allow.

Q02

How do users connect Elastic Email?

Users add their Elastic Email api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which Elastic Email actions can my agent take?

91 in total: 42 read, 34 write and 15 destructive, such as “create Domain”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Elastic Email?

Yes. Actions like “delete File” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Elastic Email too?

Yes. The same Elastic Email connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
