# Your Omnisend store. In your agent.

Source: https://corespeed.io/integrations/omnisend

Connect Omnisend to Claude Code, Codex, Cursor or any MCP agent through CoreSpeed. Your agent reads your store's contacts, segments, automations and campaigns, drafts an email or SMS campaign, and keeps the product catalog current. It uses an Omnisend API key for one store. Sending a campaign or a customer event is a separate call that approvals can hold.

## Set up an agent

Give your agent this line: `set up https://corespeed.io/SKILL.md (read it raw, e.g. with curl)`

It fetches the skill at https://corespeed.io/SKILL.md, adds the CoreSpeed MCP server, signs you in (or up), and keeps the skill for next time. Connect Omnisend after setup. Access follows the connected account and its permissions. Create an account: https://app.corespeed.io/sign-up

## A campaign draft. Ready for your review

Let your agent pick the segment, the template, and the subject line, then save a campaign draft you review in Omnisend.

You ask your agent: "Draft an Omnisend email campaign for the VIP buyers segment with our holiday template. Save it as a draft and do not send it."

It calls CoreSpeed:

- `omnisend__list_segments`: ok, 318 ms
- `omnisend__list_email_templates`: ok, 274 ms
- `omnisend__create_campaign`: ok, 602 ms

It reads from: Omnisend.

## Keep your agent. Bring your work

One CoreSpeed account, across compatible agents.

1. **Set up CoreSpeed**: Give your agent the setup line. It adds CoreSpeed and signs you in.
2. **Connect Omnisend**: Authorize the account and the content you need.
3. **Start with one task**: Ask for a summary, a brief, or a draft. Review the answer.

## Questions

### Can my agent send an Omnisend campaign?

Only as a separate call. Sending delivers real email or SMS, so approvals can hold it for a person first. How approvals work: https://corespeed.io/docs/approvals

### Which Omnisend store does it use?

The store whose API key you connect. An Omnisend key acts for one store, with the permissions chosen when it was created.

### Can it start an Omnisend automation?

Yes. Your agent can send a customer event, such as a placed order, and Omnisend uses it to start automations. Approvals can hold that call too.

### Do I have to switch agents?

No. CoreSpeed adds tools to the agent you already use: Claude Code, Codex, Cursor, or another MCP client. Each one signs in once.

### Can my agent access every account in our organization?

No. Access follows your CoreSpeed identity, each connection's visibility, and the app's own permissions. Personal connections stay private.

### Does this work without connecting an account?

No. Connect the app's account first; your CoreSpeed workspace shows what each app needs. The examples on this page use fictional data. All connectors: https://corespeed.io/docs/connectors
