# Connect Returnless to Smtp2Go

When **Request Created** fires in [Returnless](https://apiant.ai/connections/returnless), your agent runs **Add email** in [Smtp2Go](https://apiant.ai/connections/smtp2go). Describe the whole flow and it is built, tested on every scenario and kept running.

What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.

## What do you want Returnless and Smtp2Go to do together?

Give your AI client this address.

`https://mcp.apiant.ai`

One connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

### Set it up in your client

### Claude Code

Run this in the directory you want to work in.

`claude mcp add --transport http -s project apiant-ai https://mcp.apiant.ai`

Start Claude Code there, approve the server, and sign in in the browser page it opens.

[Claude Code guide (opens in a new tab)](https://apiant.ai/docs/mcp/claude-code)

### Claude, web and desktop

Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Cursor

Add the address to your MCP configuration as a server URL. Cursor signs you in in your browser.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Codex and the ChatGPT desktop app

Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in.

### Any other MCP client

Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection.

Questions

## Returnless and Smtp2Go, answered

###

### What can start an automation from Returnless?

Any of Returnless's 2 triggers in the catalog, including Request Created and Return Created. Describe the moment in plain language and your agent picks the right one.

###

### What can your agent do in Smtp2Go when something happens in Returnless?

###

### Can it also run from Smtp2Go to Returnless?

Smtp2Go has no triggers in the catalog today, so automations start in Returnless. If you need the other direction, ask: your agent reads Smtp2Go's API documentation and adds it.

###

### Do I have to build a connector for Returnless or Smtp2Go?

No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.

###

### Can my AI client use Returnless and Smtp2Go without building an automation?

###

### What happens when something fails?

Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.

###
