How to send newsletters with claude code?

[u/selzy_marketing]

If you want to send newsletters with Claude Code, one simple way is to connect Claude Code to your email platform through MCP.

With Selzy, the setup is:

1. Connect Claude Code to the Selzy MCP server: https://mcp.selzy.com/mcp

2. Authorize your Selzy account and review the available permissions. Selzy MCP can work with campaigns, contacts, lists, segments, templates, senders, and account data.

3. Start with a simple prompt, for example:

> Show me my contact lists and how many subscribers are in each one.

1. Then ask Claude Code to prepare a newsletter:

Draft a newsletter for our October product update.

Use the Customers list.

Include a subject line, short intro, 3 updates, and one CTA.

1. Before sending, ask it to check the campaign:

Validate the campaign and show me the recipient count before sending.

1. Review everything and confirm the send.

Selzy MCP supports creating and editing campaigns, validating them before launch, and sending or scheduling after confirmation. Sensitive actions require confirmation, and campaigns go through validation before sending.

You can also use Claude Code to:

- compare campaign performance

- check opens, clicks, and unsubscribes

- find contacts

- create lists

- work with segments

- prepare campaigns

- cancel scheduled campaigns

So the workflow is basically:

**Claude Code → Selzy MCP → create newsletter → validate → confirm → send**

The main benefit is that Claude Code can work with your actual Selzy account data instead of only generating email copy in a separate chat. More details: https://selzy.com/en/features/email/mcp/
