Custom Agents

Autonomy Modes

Control how much independence your agent has when replying to emails.

Autonomy Modes

Your agent can operate at three different levels of independence. Choose the mode that matches your comfort level and use case.

The Three Modes

1. Human in the Loop (Safest)

How it works:

  • Email arrives
  • Agent reads and understands it
  • Agent drafts a response
  • You review the draft
  • You approve or reject
  • Email sends (or doesn't)

Best for:

  • Getting started with a new agent
  • Complex or sensitive domains
  • High-stakes emails (legal, contracts, complaints)
  • Building confidence in the agent

Pros:

  • Complete control over every response
  • Lowest risk of mistakes
  • Great for learning how the agent thinks
  • Can provide feedback to improve responses

Cons:

  • Slowest mode (you must review each email)
  • Requires your active attention
  • Not scalable for high-volume emails
  • Can become a bottleneck

Example use case: Customer support agent handling complaints and refund requests


2. Semi-Autonomous (Balanced)

How it works:

  • Email arrives
  • Agent reads and understands it
  • Agent drafts a response
  • Agent sends after 2-minute delay
  • You can cancel within 2 minutes
  • Email sends (unless you cancel)

Best for:

  • Routine emails with low risk
  • Once you trust the agent's judgment
  • High-volume support tickets
  • Common questions and responses

Pros:

  • Faster than Human in the Loop
  • Safety net: you can still cancel
  • Good balance of speed and control
  • Scales better for volume

Cons:

  • Requires you to monitor emails
  • 2-minute window is tight
  • Some emails might send before you see them
  • Need to be responsive

Example use case: Support agent answering FAQs, sales agent confirming meeting times


3. Full Auto (Fastest)

How it works:

  • Email arrives
  • Agent reads and understands it
  • Agent sends response immediately
  • No review or approval needed

Best for:

  • High-volume, low-risk emails
  • Routine confirmations and acknowledgments
  • Emails you're confident the agent handles well
  • Scaling to thousands of emails

Pros:

  • Fastest response time
  • Fully automated, no human intervention
  • Best for scaling
  • Improves customer experience (instant responses)

Cons:

  • Highest risk of mistakes
  • No safety net
  • Can't review before sending
  • Mistakes go directly to customers

Example use case: Automatic confirmations, receipt acknowledgments, simple FAQ responses


Week 1: Human in the Loop

  • Create your agent
  • Send 20-30 test emails

  • Build confidence

Week 2: Semi-Autonomous

Real-World Examples

  • Receipt acknowledgments
  • Out-of-office replies
  • Routing confirmations

Sales Agent: Mostly Semi-Auto

Human in the Loop:

  • Enterprise deals (>$100k)
  • Custom pricing requests
  • Legal/contract questions
  • Competitor mentions

Semi-Autonomous:

  • Lead qualification responses
  • Product question answers
  • Demo scheduling confirmations
  • Follow-up emails

Full Auto:

  • Initial lead acknowledgments
  • Meeting confirmation reminders
  • Simple FAQ responses

Switching Modes

You can change autonomy mode anytime:

  1. Go to agent settings
  2. Click "Autonomy Mode"
  3. Select new mode
  4. Changes take effect immediately

Note: Changing modes only affects new emails. Existing drafts keep their original mode.


Best Practices

Start Conservative

Begin with Human in the Loop. It's easier to move to Full Auto than to recover from mistakes.

Test First

Before switching modes, send 10-20 test emails and review responses.

Monitor Escalations

If escalation rate is high (>30%), stay in Human in the Loop longer.

Use Escalation Rules

Escalation rules are your safety net. Define them clearly so risky emails don't go to Full Auto.

Review Weekly

Even in Full Auto, review a sample of sent emails weekly to ensure quality.

Document Your Rules

Write down which emails go to which mode. Share with your team.


Troubleshooting

Q: Agent is sending bad responses in Semi-Auto
A: Switch back to Human in the Loop. Review responses and update instructions. Test more emails before trying Semi-Auto again.

Q: 2-minute window is too short
A: Semi-Auto isn't right for you. Use Human in the Loop instead. You can always move to Full Auto later.

Q: Too many escalations
A: Your escalation rules might be too broad. Review and tighten them. Or the agent's instructions need clarification.

Q: Want to use Full Auto but worried
A: Use Semi-Auto first. Once you're comfortable, switch to Full Auto. You can always go back.
