Emailx brings contacts, campaigns, saved conversations, and results into one workspace. Use the developer platform to connect those records to your CRM, build internal reporting, or give an assistant a carefully scoped set of actions. Start with a read. Discover your workspaces, choose a channel, and build from there.

Make your first request

Authenticate and read your workspace data in a few steps.

Explore the API

Fifty-five REST operations, with schemas and copyable examples.

Connect an assistant

Forty-five focused MCP tools for scoped reads and edits.

Use your terminal

Script the same API with predictable commands and JSON.

Choose your interface

All three interfaces use the same workspace permissions. Agency access follows the member’s current client assignments; a credential never grants access to every customer.

What you can build today

  • Keep contacts in sync. Find an email address, create or update a profile, and respect suppression.
  • Prepare campaigns for review. Create inactive drafts, attach known prospects, and return to the app to review them.
  • Understand saved activity. Read campaign-linked replies, stored sender metadata, and all-time delivery totals.
  • Pause future activity. Inspect a campaign and pause it when the operator requests it.
  • Manage template settings. Read and save regular or smart email template fields. These writes do not generate or approve copy.
  • Import explicit LinkedIn URLs. Queue up to 100 profile URLs for lookup on an eligible manual draft. The feature is host-gated and can consume provider lookup quota. See templates and LinkedIn imports.
  • Activate a reviewed LinkedIn draft. A ready, unexpired review plus explicit confirmation can activate an eligible manual campaign for native scheduled dispatch when the host enables execution. A receipt means local activation, not delivery. See review and launch.
The v1 beta supports reviewed activation only for eligible manual LinkedIn campaigns through native scheduled dispatch when execution is enabled. It also supports explicitly confirmed replies to saved inbox conversations when the host enables reply execution. Reviewed resume of paused LinkedIn campaigns, reply drafts and signed webhooks for operation outcomes each have their own scope. It does not support immediate batches, campaign deletion or broad provider search. Email campaign generation, exact-message approval, and reviewed scheduled launch are separate gated API actions.

Before you scale

Request an expiring beta key from your Emailx account contact. Then read API request limits and recommended sending limits. They measure different things: requests to Emailx and activity from your sending accounts.
