How to Schedule a WhatsApp Message (on iPhone and Android, No Sketchy Apps)

You want to wish someone happy birthday at midnight, remind a client about tomorrow's 9 am appointment, or tell your landlord the rent is paid on the 1st of every month. But at that hour you'll be asleep, driving or in a meeting.

WhatsApp won't do it for you. Neither the iPhone nor the Android app has a button to schedule a message, and the apps that promise to usually want accessibility permissions or just remind you to send it yourself.

An AI connected to your WhatsApp can. You just say:

  • "Send my mom 'Happy birthday 🎂' tomorrow at 12:00 am."
  • "Remind Carlos about his appointment on Thursday at 9 am."
  • "On the 1st of every month at 10 am, send my landlord 'Hi, the rent is transferred'."

This guide shows how to do it with WhatsApp MCP, using Grok Bot as the example. It works the same in ChatGPT, Claude and Muse. No install, no coding, about two minutes.

Step 1: Connect your AI to WhatsApp

  1. Go to wa-mcp.com and pick your AI under Which AI do you use?.
  2. Click Get my WhatsApp key and follow the steps on the page. For Grok Bot, one click opens it with the setup prompt ready to send.
  3. Link your WhatsApp by scanning a QR code or typing a pairing code, just like linking WhatsApp Web.

Step-by-step guides for each AI: Grok Bot, ChatGPT, Claude and Muse.

Step 2: Say what to send, to whom and when

Ask in your own words. Name the contact as it's saved in your phone, or give the number:

  • "Schedule for Friday at 8 am: 'Good morning, confirming today's delivery' to Peter Ruiz."
  • "On December 24 at 11:59 pm send my sister 'Merry Christmas'."
  • "Send the Tuesday Football group 'Tonight at 8, who's in?' at 5 pm."

The AI shows you the message, the contact and the time before scheduling it. It uses your time zone; if you're traveling or the message is for another country, say which: "at 9 am London time".

You can schedule a file too: "Send Laura this quote PDF on Monday at 10."

Step 3: Make it repeat (automatic reminders)

A scheduled message can repeat:

  • Daily: "Every day at 7 am send my dad 'Take your pill 💊'."
  • Weekly or every two weeks: "Every Monday at 9 remind my team about the meeting."
  • Monthly: "On the 1st of every month, a payment reminder to my tenant." If a month doesn't have that day (say the 31st), it goes out on the month's last day.
  • Quarterly, every six months or yearly: "Every March 15 wish Ana happy birthday."

You can set an end: "…until June 30."

Step 4: Check or cancel what's scheduled

  • "What messages do I have scheduled?"
  • "What am I sending Carlos this week?"
  • "Cancel the rent reminder."

Cancelling a repeating message cancels all its remaining sends.

Ideas

  • Appointments: reminders the day before for clients of your clinic, salon or workshop.
  • Payments: a friendly reminder on the day a payment is due.
  • Birthdays and dates: wishes at the exact time, every year.
  • Work: a message that lands during business hours even if you write it at night.

Write each message for its person. Sending the same text to many contacts, especially people who have never written to you, can get your number banned by WhatsApp. WhatsApp MCP spaces out your sends and protects your new conversations, but a personal message to people you already know is the safest.

Frequently asked questions

Does WhatsApp have a schedule message option? No. Neither WhatsApp nor WhatsApp Business has a button to schedule a regular message to a contact. That's why you need something outside the app, like an AI connected to your WhatsApp.

Does it work on iPhone and Android? Yes. The message isn't sent by an app on your phone: WhatsApp MCP sends it as a linked device, like WhatsApp Web. Your phone model doesn't matter.

Does my phone need to be on, or the app open? Neither WhatsApp nor your AI needs to be open at send time. Your phone just needs to go online now and then, as with WhatsApp Web, so the linked device stays active.

How far ahead can I schedule? Up to one year.

Does the message show it was scheduled? No. It arrives like any other message from you. Before sending, WhatsApp MCP shows "typing…" for a few seconds, like a person would.

Is it free? Scheduling is a Pro feature (from US$4 a month, billed yearly), along with sending files, opening the photos, voice notes and files you receive, and editing, reacting to and deleting messages. You can try it during the 1-hour free trial. Reading your chats, searching messages and replying to people who wrote to you are free.

Does it work with WhatsApp Business? Yes. It connects to the number you already use, on regular WhatsApp or WhatsApp Business.

Is my data private? WhatsApp MCP stores your messages only so your AI can read and search them, and deletes them automatically after 90 days. Your data is never sold or used to train AI models. Messages your AI reads are also processed by its provider (for example xAI for Grok Bot) under its own privacy policy.

Got a message to send later? Connect your AI to WhatsApp and ask it to schedule it. Setup is free and no credit card is needed.
