Schedule WhatsApp Messages: How to Send Later

Two different mechanisms both get called scheduling, and telling them apart decides which one you should be using.

• A scheduled newsletter is you picking the moment. You write a campaign, choose a segment, set a date and a time, and it reaches everyone in that segment at once. The newsletter overview explains how template, content and segment fit together.
• A flow is the message picking its own moment. It reacts to an event — an order, an abandoned checkout, a chat-in — and reaches each contact at the point in their own timeline where the message makes sense.

A promotion that ends on Sunday night is a newsletter. A reminder about a cart left on Tuesday afternoon is a flow. Most shops need both, and most start by trying to do the second job with the first — a manual blast every time something happens, which stops scaling in the low hundreds of contacts.

Scheduling lives in the send panel, which is the last step of a newsletter rather than a separate screen. It opens next to your message preview, so the message stays visible while you set the timing, and nothing leaves your account until you confirm.

1. Build the newsletter under Newsletter — one message, or several in sequence as Message 1, Message 2 and so on.
2. Add what the message needs: an image, a video or a PDF, buttons for the call to action, personalised variables such as the first name, and a footer.
3. Open the send panel with Send on a draft, or with Send or schedule from the newsletter's detail view.
4. Choose Send later as the sending method. The When field takes a date and a time and shows the timezone it applies.
5. Pick the segment that receives it. Every segment is listed with its contact count, so you see the size of the send before you commit to it. If the audience does not exist yet, build it first with the Segment Builder.
6. Send yourself a test — one message to a single contact you pick — and check formatting, variables and links in a real chat.
7. Confirm with Schedule Newsletter. The campaign is marked Scheduled and goes out on its own at that moment.

The full panel, including the two notices it puts in front of you before you confirm, is documented in Newsletter: Sending. One of them is worth repeating: WhatsApp messages are billed by Meta, so a larger segment means a larger bill. The panel shows you that before the send rather than after it.

A scheduled newsletter is not final. Content and time both stay editable until it goes out, and you can cancel it outright. That matters more than it sounds, because most of the reasons to move a send — a stock problem, a delivery delay, a news event you would rather not sit next to — turn up after the schedule is set.

Not because it lifts your open rate. WhatsApp gets read either way: published benchmarks put read rates above 90% against email open rates of 30–40%, which is a benchmark band rather than a guarantee, and how we calculate the forecast shows how conservatively we work with it. What scheduling buys you is control over the moment the offer is live and over your ability to answer.

• Line the send up with the offer. A discount that starts on Friday should arrive on Friday, not on Thursday evening when the code does not work yet.
• Send when someone can reply. WhatsApp is a two-way channel. A campaign that lands at 22:00 collects replies nobody reads until morning, and a slow reply reads as indifference in a chat in a way it never does in an inbox.
• Keep your own week sane. Booking Friday's drop on Tuesday is the difference between a campaign you planned and one you improvised.
• Space your sends out. The send panel says it plainly: send at a moderate frequency and to the interests of your segment. Frequency and relevance are what keep block and report rates low.

Cadence and content are a marketing question rather than a product one. Our WhatsApp newsletter playbook for food and beverage stores works through both with a real example, and the industry playbooks show what a sensible rhythm looks like per vertical.

Everything that reacts to a customer belongs in a flow, where the timing is measured from the event instead of from the calendar. You build it once and it keeps its own schedule.

• The trigger sets the starting moment: a purchase in your connected Shopify store, an abandoned checkout, or a chat-in from a QR code or a link.
• Delay blocks set the gaps inside the flow — an hour after the checkout was abandoned, a few days after delivery, whatever the sequence needs.
• Smart Activation decides the send moment per contact instead of sending to everyone at once, which is what you want for contacts you have not spoken to in over twelve months.

Winning back abandoned carts is the clearest case. The same message is worth almost nothing on a fixed weekly schedule and a great deal an hour after the cart was left. The flow builder handles the timing once you have chosen the trigger and the gaps.

Reach, not timing. A perfectly scheduled campaign that can only be delivered to a third of your customers is worth less than a clumsily timed one that reaches most of them.

Customer Contact Coverage — the share of your last twelve months of Shopify customers you can reach on WhatsApp at all — typically starts at 35–55% and reaches 85%+ in about 60 days once the collection points are live. The largest single lever is the phone number field in the Shopify checkout: offered actively rather than merely present, capture rises from 22% to 65–70%.

It matters because the two audiences barely overlap. Across Keaz shops the split runs 24% email only, 38% both, 34% WhatsApp only, 3% neither — about a third of your audience is reachable on WhatsApp and nowhere else. WhatsApp complements email here; it does not replace it. For the wider DACH picture, the bevh publishes its annual study Interaktiver Handel in Deutschland (bevh, January 2025).

One thing to settle before you book any send: marketing on WhatsApp runs on explicit, documented and revocable consent — the principle sits in Article 7 of the General Data Protection Regulation (2016). In Keaz you enforce it through the opt-in level on the contact, and through the minimum level set on a flow's starting point.

• Scheduling a campaign that should have been a flow. If the message reacts to something one customer did, a fixed send time is guesswork.
• Setting the time without reading the timezone. The When field shows which one it applies. Check it once rather than discovering it after the send.
• Starting the schedule before the segment exists. You cannot confirm without one, and a segment built under time pressure is how the wrong audience gets picked.
• Skipping the test send. A broken variable or a wrong link is cheap to catch beforehand and expensive afterwards, because a scheduled send reaches the whole segment at once.
• Treating a booked send as locked. It stays editable and cancellable. If the reason for the campaign disappears on Thursday, cancel it on Thursday.
• Scheduling more sends than you can staff. A campaign that lands when nobody can answer turns a conversation channel into a broadcast one.
• Sending to everyone every time. A larger segment costs more and is relevant to fewer of the people in it. Narrower and more relevant beats bigger.
• Booking sends onto a list you have not grown. Coverage sets the ceiling on what any send time can be worth.

Can I schedule a WhatsApp newsletter to a single contact? No. Sending always goes through a segment, so build one containing the contacts you mean and select it in the send panel. The test send is the exception — that goes to one contact you pick by name or phone number.

How precise is the scheduling? To the minute. The When field takes a date and a time and shows the timezone it applies, so you can check it before you confirm.

Can I still change or cancel a scheduled newsletter? Yes. Content and time stay editable until the moment it goes out, and you can cancel it entirely.

What is the difference between scheduling and automating? Scheduling fixes a moment on the calendar for a whole segment. Automating ties the moment to an event, so each contact receives the message at their own point in the sequence.

How do I know what a scheduled campaign earned? Every newsletter has its own evaluation covering revenue, cost, sent, delivered, read and click-through rate, with revenue attributed to the campaign through its discount code.
