One API for the Full Outreach Loop
Everything you do in the dashboard, you can now do from your own code. The MailBeast API is live at developer.mailbeast.ai - connect mailboxes, launch campaigns, load leads, read replies, and discover new leads through a single key.
Getting Started
Open Settings → API Keys in your dashboard, create a key, and copy the secret - it's shown once and can't be recovered afterwards.
What You Can Do
Email accounts. Connect any provider, including Gmail and Outlook with an app password, and pause, resume, or delete mailboxes. Check verification status before you send.
Campaigns. Create a fully-configured campaign in one call, then start, pause, resume, or delete it. Send a test email before you go live.
Leads. Add 1-100 leads per request, filter them, run bulk mutations - status changes, tagging, deletion - and search across every campaign in your workspace by email.
Emails. List, read, reply, forward, and delete. Read state is tracked at the conversation level, the same way your inbox sees it.
Analytics. Engagement metrics for a single campaign, time-series data for your own charts, and a workspace-wide roll-up - with optional breakdowns by sending account, sequence, and bounce category.
Lead Finder. List your searches and pull their results, so discovery feeds your pipeline without a manual export.
Workspace. Read your subscription, track usage against your plan, and mint or revoke further keys programmatically.

The full reference, guides, and an OpenAPI spec you can point your own tooling at are at developer.mailbeast.ai.
API access is available on the Pro+ plan and on enterprise contracts.
