Can you schedule WhatsApp messages natively?

The regular WhatsApp app has no option to schedule a message to a chat. Workarounds on phones rely on reminder apps or automation apps that may stop working after an update.

On a computer, you can schedule WhatsApp messages on WhatsApp Web with a Chrome extension that sends them at the chosen time from your open WhatsApp Web tab.

The WhatsApp Business app offers away and greeting messages, which send automatically when someone writes to you, but those are replies, not messages you plan for a time. If you need a reminder to go out at a set hour, you need a scheduler.

Before choosing any scheduling tool, check two things: where the message is sent from, and what must be running at the scheduled time. A tool that sends from your own WhatsApp Web needs that tab open; nothing is sent from a server on your behalf.

This guide covers both: what WhatsApp can and cannot do on its own, how scheduling works on WhatsApp Web, and the habits that keep scheduled campaigns from failing quietly when nobody is watching the computer.

For one-off personal reminders, a phone alarm that tells you to send the message yourself is still the simplest option. Scheduling pays off when the same kind of message goes to many customers at a set time, such as reminders for tomorrow's appointments.

How scheduling works in Wassender

When you review a campaign, choose Schedule under When, pick a date and time, and confirm Schedule campaign. The scheduled job appears in the campaign screen, where Send now starts it early and Cancel removes it.

Scheduling is part of Wassender Unlimited.

What must stay open

Because messages are sent from your own WhatsApp Web, a scheduled campaign needs Chrome running and WhatsApp connected at the scheduled time. Set your computer not to sleep while plugged in, and leave Chrome open.

If the browser was closed at the scheduled time, the schedule waits for you: open it again, review it in Reports and choose Send now.

Sending hours and daily limits

Sending hours define when a campaign may run, for example 09:00 to 18:00. If you start outside those hours, the confirmation offers to wait for the next allowed time.

A daily limit defines how many messages may be attempted per day. With 150 recipients and a limit of 100, the campaign continues on the next day.

Example schedules that work

Clinic reminders: schedule at 18:00 the day before each appointment day, with "Hi [name], a reminder of your appointment tomorrow at [time] with [doctor]. Reply 1 to confirm or 2 to reschedule." Evening reminders give people time to rearrange plans; morning-of reminders work for same-day changes.

Payment due dates: schedule for 10:00 on the due date, a polite time that is neither too early nor late in the day. "Hi [name], a friendly reminder that invoice [invoice] for [amount] is due today. Reply here if you have already paid."

Weekend offers: schedule Thursday at 17:00 for a Friday and Saturday offer in many Gulf countries, or Friday morning where the weekend is Saturday and Sunday. Combine with sending hours such as 09:00 to 20:00 so a large list that runs long never spills into the night.

Common scheduling mistakes

The laptop went to sleep: the scheduled time passed with the lid closed. Change power settings so the computer stays awake while plugged in, keep Chrome open with WhatsApp Web connected, and check the campaign screen the next morning; a missed schedule waits for you to choose Send now.

WhatsApp Web was logged out: if your phone was offline for a long time or you logged out the linked device, WhatsApp Web may need to be linked again. Open it before an important scheduled run to confirm it is connected.

Time zone confusion: the time you pick is your computer's local time. If customers are in another country, convert the time before scheduling.

A daily limit that is too low for the deadline: 300 reminders with a daily limit of 100 will take three days. If everyone needs the message today, split the list or start earlier.

Scheduling recurring messages without repeating work

Many scheduled messages repeat: weekly class reminders, monthly payment reminders, appointment reminders every evening. Save the message as a template and keep a spreadsheet that you update with the next batch of names, dates and amounts. Each time, import the updated sheet, choose the template and schedule the campaign for the right time.

A simple weekly routine works for most shops. On Sunday, export next week's bookings or due payments, check the phone and date columns, and schedule one campaign per reminder day. Look at the campaign screen to confirm every scheduled job is listed with the correct time. Use Send now if something needs to go earlier, or Cancel if a plan changes.

After each scheduled run, check the report. Replies tracked over the following days show who confirmed, and Wassender can help you follow up with people who did not reply. Keep follow-ups polite and spaced out; one reminder and one follow-up are usually enough, and anyone who asks to stop is added to the opt-out list automatically.

Good uses for scheduled messages

Appointment reminders the morning before, payment reminders on the due date, and offers that should land at a sensible hour in your customers' time zone. Avoid late-night sends; they annoy people and get more reports.

Step by step

  1. Prepare a campaign in Wassender with your list and message.
  2. On the review step, choose Schedule under When.
  3. Pick the date and time, set sending hours and a daily limit if needed.
  4. Confirm Schedule campaign and check it appears in the campaign screen.
  5. Keep Chrome open with WhatsApp Web connected and the computer awake at that time.

Plan: Scheduling needs Unlimited. The free hour of Unlimited from your first campaign lets you try it; after that, plans are US$9.99 a month, US$79 a year or US$99 once. Nothing renews unless you switch on auto-renew for Monthly at checkout, and you can cancel that anytime.

Frequently asked questions

Can I schedule a WhatsApp message without an app?

WhatsApp has no built-in scheduler for regular chats. On a computer, a WhatsApp Web extension like Wassender can schedule campaigns.

Does my computer need to be on?

Yes. Chrome must be running and WhatsApp Web connected at the scheduled time, because messages are sent from your account in that tab.

What if I miss the scheduled time?

The schedule waits. Open Chrome and WhatsApp Web, review it in Reports and choose Send now.

Can I schedule a message for one person?

Yes. A campaign can have a single recipient, so you can schedule a reminder to one customer.
