How SenderPermit works

Use the email API for your application’s messages. Add AI reply drafting when you want it, with rules that keep you in control.

  1. Connect your domain

    Verify your sending domain to send from your own addresses. Configure receiving when you want incoming email to reach the platform.

  2. Send from your app

    Create an API key and send welcome emails, notifications, and other transactional messages. Track their activity in the dashboard.

  3. Put AI to work

    Assign an AI agent an email identity and instructions for drafting replies to incoming messages. AI drafting requires a separately enabled allowance.

  4. Control what gets sent

    Set policies for the agent’s replies: allow sending, require human approval, or block sending. When no policy matches, human approval is required.

  5. See what happened

    Review conversations, delivery activity, approvals, and the audit trail together. Follow a reply from its draft to its recorded outcome.

Email plans do not include AI drafting. New workspaces start with 0 AI drafts. See allowances and pricing →

THE PLATFORM

The email layer behind your product.

Everything developers expect from email infrastructure, with controls for autonomous software.

01

Send API

One endpoint for transactional messages, with API keys, delivery IDs, and logs.

02

Domains

See verified sending domains and their receiving capabilities in one workspace.

03

04

Webhooks

AI WITH ACCOUNTABILITY

Give agents email access without giving up control.

Identity→Policy→Approval→Delivery→Audit

Give your AI agent an email identity and let it draft replies to incoming messages. Your policies determine which replies may be sent, which need approval, and which are blocked. Follow every decision in the audit trail.

AI-generated replies can be wrong. Require human review when accuracy, tone, or sensitive information needs attention. Policies control whether a reply may be sent; they do not guarantee its content is correct.
