01
The WhatsApp 24-hour window, explained for shop owners
Why you can type anything you like to a customer one day and get blocked the next — and how to design your automations around it.
02
The truth about WhatsApp per-user marketing limits
The widely-repeated 'two per 24 hours' figure does not appear in Meta's documentation. What Meta describes is adaptive and has no published number.
03
Utility or marketing? How Meta categorises your template
Why adding a discount code to your order confirmation can turn a free message into a charged one that US customers never receive.
04
Why your WhatsApp template was rejected, and how to fix it
A rejected template blocks your whole automation. These are the causes we see most, each with the fix.
05
What WhatsApp automation actually costs a small store
Why a $25 plan can produce a far larger invoice, and how to design flows where most messages cost nothing.
06
WhatsApp error codes, translated for shop owners
A reference written from the customer's side of the conversation rather than the developer's.
07
Messaging limits and tiers, and how to move up them
Why a new account can only reach 250 people a day, and the two ways to get past it.
08
WhatsApp marketing is paused for US numbers — what's left
If you sell to US customers, half the WhatsApp playbook does not apply to you. The half that does is still worth having.
09
WhatsApp opt-in rules: what Meta requires, and what the law does
Meta allows a general opt-in and does not require double opt-in. Your regulator may disagree — and it is the regulator that fines you.
10
How many WhatsApp templates can you have?
A limit nobody mentions until you hit it — and you hit it faster if you make a template per product.
11
What you cannot sell or promote on WhatsApp
If your category is on this list, no amount of careful template wording will fix it. Better to know before you build.
12
Your WhatsApp Business number was restricted. Now what?
Most merchant bans trace to one decision made at signup — and it isn't what you were sending.
13
Your WhatsApp quality rating turned yellow. Do this.
Yellow is not a caution. It is the last cheap moment to fix something.
