Integration

BigMailer integration

BigMailer is an email marketing platform for multi-brand senders that delivers through Amazon SES or other connections. Manage brands, contacts (create, upsert, batch upload up to 1,000), lists, custom fields, segments, templates, senders and their DNS verification, brand properties and message types; create and update bulk, RSS and transactional campaigns, send a transactional email or a test campaign, and read campaign status and statistics. User management and uploading a campaign suppression list (a CSV file) are left to the BigMailer app. Authentication is an API key from the BigMailer account, sent in the X-API-Key header.

Connect BigMailer How integrations work

Ask it in chat

Say what should happen.
The workflow builds itself.

When this happens, do that in BigMailer.Built from the 74 BigMailer tools below, on the connection you add once.

What you can do with BigMailer

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.

Use BigMailer from Claude Code, Cursor or Codex

Connect BigMailer in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its BigMailer 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"
      }
    }
  }
}
