Let a weekend AI agent answer positive replies on Saturday and Sunday

On weekends, positive replies get a Weekend label. A reply agent scoped to that label answers them, while your team keeps handling weekday replies by hand.

Why teams run it

Speed to lead holds on weekends without anyone on call.

Set it up in Master Inbox

In Master Inbox, open Settings, then Workflows, and click Add a workflow.
Name it Let a weekend AI agent answer positive replies on Saturday and Sunday.
Set the trigger to Add Label and choose Interested or Meeting request.
Add a condition: Day is Saturday or Sunday.
Add the action Add labels: Weekend agent.
Save the workflow and switch it to Active.

Or create it with the API

Everything in the workflow builder is also in the Master Inbox API. This request creates the same workflow. Replace the example ids with your own label, list and campaign ids from GET /workflows/filter-fields. This workflow also uses conditions: add them under trigger_config.conditions, as shown on the conditions page.

curl -X POST https://api.masterinbox.com/api/api-webhook/v1/api/workflows/create-workflow \
  -H "Authorization: Bearer $MASTER_INBOX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{

Or ask Claude, ChatGPT or Grok to build it

Our workflow guide is written for AI agents to read. Give your assistant your API key and this prompt:

Read https://app.masterinbox.com/public-workflow-api.md and use my Master Inbox API key to create this workflow: "Let a weekend AI agent answer positive replies on Saturday and Sunday". First call GET /workflows/filter-fields and look up my label, list and channel ids, then create the workflow and tell me what you set up.

Questions

Can the agent send on its own?

Yes, if you set that agent to fully automated. Many teams start in human-in-the-loop mode.

How do weekday replies stay human?

Only the weekend label is in that agent's scope, so weekday replies are untouched.

Can I build this workflow through the API?

Yes. Send the create-workflow request shown on this page with your Master Inbox API key. The API checks the payload first and lists every problem by field if anything is off.

Which plan includes this?

This workflow works on the Team plan. Every plan has unlimited users and starts with a free 7-day POC.
