AGENT APPROVAL NOTIFICATIONS
Autonomous AI agents sometimes need a human in the loop before they act. Fastsend lets your agent send an approval request by SMS or email — the fastest way to get a real person's attention before proceeding.
High-value transactions
Request confirmation before an agent places a large order, sends a bulk communication, or modifies production data.
Security-sensitive actions
Notify a security contact when an agent detects suspicious behavior or is about to change access permissions.
Content review requests
Ask a human to review AI-generated content before it is published or sent to a large audience.
Workflow escalations
Surface edge cases your automation cannot resolve — text or email the right person with full context and a clear request.
// example

Agent: Approval request sent. Waiting for response.// why sms and email
- SMS is high-attention — approval requests reach reviewers even away from their desk
- Email provides space for full context, links, and reference data
- Your agent can choose the channel based on urgency or the reviewer's preference
- Both channels share the same
