Integration

SMTP2GO integration

SMTP2GO is an email and SMS delivery service. Send standard, templated, MIME and batch emails, schedule or cancel scheduled emails, search delivery activity (processed, delivered, bounced, opened, clicked and other events) and archived messages, read sending statistics (bounces, spam, unsubscribes, monthly cycle), send and review SMS, and manage sender domains, single sender emails, allowed senders and recipients, suppressions, templates, webhooks and subaccounts. The deprecated sent-email search is replaced by activity search. API key management and SMTP user and IP authentication management are not exposed, because their routes return or set sending passwords. Authentication is an API key sent in the X-Smtp2go-Api-Key header.

Say what should happen.
The workflow builds itself.

When this happens, do that in SMTP2GO.Built from the 55 SMTP2GO tools below, on the connection you add once.

What you can do with SMTP2GO

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Add, 8 operations

add_allowed_recipientsAdd allowed recipientsPOSTAdd one or more email addresses and domain names to your Allowed Recipients List. Further details of the associated setting are found in the SMTP2GO Guides.

add_subaccountAdd subaccountPOSTAdds a new subaccount on your master account. Note: This end-point is rate limited to 50 calls per hour.

Use SMTP2GO from Claude Code, Cursor or Codex

Connect SMTP2GO in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its SMTP2GO operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}
