WhatsApp Template Approval Predictor

Every message a business sends outside the 24-hour service window has to use a pre-approved template, and Meta rejects a large share of first submissions for reasons that were knowable in advance: a variable at the end of the body, a bit.ly link, promotional wording in a Utility template. This tool reads your draft in the browser, runs it against the rejection triggers Meta documents publicly, and gives you an approval-likelihood score plus the specific fixes — before you spend a review cycle finding out the hard way. Free, no signup, and nothing you paste ever leaves your machine.

Lint your template before Meta sees it

Paste the draft exactly as you would submit it. The tool checks it against Meta's documented rejection triggers — placeholder rules, length limits, category mismatch, prohibited content, link rules, button limits — and tells you what to fix before you spend a review cycle. Everything runs in your browser; nothing is uploaded.

This is a pre-submission lint, not Meta's decision. Meta's review combines automated checks, machine-learning classification, and policy review, and it sees things this tool cannot — your sample values, template name, and business history. A clean result here improves your odds; it does not promise approval, and Meta can reject or recategorize for reasons outside any wording check.

Why templates get rejected at all

The WhatsApp Business API splits conversations into two regimes. Inside the 24-hour service window a business can reply freely. Outside it, every business-initiated message must use a template that Meta has reviewed and approved in advance — that is the mechanism that keeps WhatsApp inboxes from turning into email spam folders. Review is fast, usually minutes to a few hours, but a rejection still costs you a full edit-and-resubmit loop, and repeated sloppy submissions drag on the account's standing.

The frustrating part: most rejections are mechanical. Meta publishes its formatting rules and rejection reasons, and the same handful of mistakes account for the bulk of failed reviews. Those are exactly the mistakes a deterministic lint can catch before submission, which is what this tool does.

What the checks cover

Placeholder rules

Variables must be numbered {{1}}, {{2}}with no gaps, no names, and no spaces inside the braces. A template cannot begin or end with a variable, two variables cannot sit back to back, and a body made mostly of placeholders trips the documented "too many parameters relative to message length" rejection. The tool checks all of these, plus floating lines that consist of a placeholder alone.

Length and formatting limits

The body caps at 1,024 characters, text headers and footers at 60, button labels at 25. Headers take at most one variable and no emoji; footers take none of either. Beyond the hard limits, the lint flags formatting that reads as spam to reviewers and recipients alike: ALL-CAPS shouting, emoji pile-ups, and runs of exclamation marks.

Category mismatch

The most expensive mistake is not a rejection — it is miscategorization. Utility templates must relate strictly to an agreed transaction: an order, a booking, an account change. The moment a "your order shipped" message adds "and here's 20% off your next purchase", Meta treats it as Marketing, which is priced higher and, since the 2023 pricing split, reviewed more sceptically. The tool detects promotional wording in Utility drafts and OTP-shape violations in Authentication drafts, where custom copy, links, and emoji are not allowed at all.

Content policy and spam patterns

Templates promoting goods and services the WhatsApp Commerce Policy prohibits — weapons, drugs, tobacco, gambling, adult services, payday loans — are rejected outright, and rewording does not help. The lint also flags phrasing that recurs in rejected templates ("you have won", "100% free", "guaranteed") and the scare-pressure framing ("your account will be suspended unless…") that pattern-matches phishing.

Links and buttons

Link shorteners are a documented rejection: bit.ly and its cousins obscure the destination, so Meta refuses them in bodies and in URL buttons. Raw IP-address links fail for the same reason. On buttons, the platform allows at most two URL buttons, and labels over 25 characters will not pass. The tool treats quick-reply counts above three as a soft warning — newer API versions allow more, but menus that long convert poorly.

How the score is built

Every check lands in one of three buckets. A blocker is a documented rejection trigger or hard platform limit; each one costs 25 points, because any single blocker is usually enough for a rejection. A warningis a risk pattern that shows up disproportionately in rejected templates without being an automatic fail, and costs 8. What remains maps to three bands: 80 and above reads "likely approved", 50 to 79 "at risk", below 50 "likely rejected". Any blocker caps the grade at "at risk" no matter the number.

Read the score as a lint result, not a verdict. Meta's review also weighs things no wording check can see: the sample values you attach, your template name, your business verification status, and the account's messaging history. The copyable submission checklist in the tool covers that half.

If the template still gets rejected

Meta shows the rejection reason in WhatsApp Manager. Fix the flagged issue and resubmit — do not resubmit the identical template unchanged, which reads as review-gaming. If you believe the rejection is wrong, there is an appeal path in Business Manager support. And if the reason is "incorrect categorization", take the hint: resubmit as Marketing rather than shaving words off a promotional message to sneak it through Utility. The per-message price difference is real but small next to the cost of a template pause on your broadcast campaigns.

Where this fits in a WhatsApp workflow

Template approval is one step in a longer chain. If you are still costing out the channel, the WhatsApp API cost calculator models per-conversation pricing by country and category, and shows why a Utility-vs-Marketing recategorization changes your bill. Once templates are approved, the click-to-chat link generator and QR code generator handle the entry points that pull customers into the session window where no template is needed. For the campaign side (audience building, opt-in, send cadence), start with the WhatsApp broadcast campaign guide; for wiring a bot to answer the replies, the WhatsApp chatbot tutorial walks through it end to end.

FAQ

Is my template sent to a server?

No. The lint runs entirely in your browser as client-side JavaScript. Your draft, the score, and the report are not uploaded, stored, or logged — closing the tab discards everything. It is safe to paste real campaign copy.

Does a "likely approved" score guarantee approval?

No. The score means the draft contains none of the documented rejection patterns this tool checks for. Meta's review also uses machine-learning classification and sees your sample values, template name, and account history. Treat a clean pass as "the knowable mistakes are fixed", not as a promise.

Why does the category choice matter so much?

Since Meta split conversation pricing by category, Marketing templates cost several times more than Utility in most countries — and Meta actively reclassifies Utility submissions that carry promotional content. Getting the category honest at submission avoids both the rejection loop and a surprise on the invoice. The cost calculator shows the exact per-country difference.

How long does Meta's review take?

Usually minutes to a few hours; Meta states up to 24 hours, and occasionally longer for flagged accounts. Rejections arrive with a reason code in WhatsApp Manager. Note that after approval, edits re-enter review and are rate-limited to one edit per day and ten per month per template.

Can I check templates written in languages other than English?

The structural checks — placeholders, lengths, links, buttons — work on any language. The vocabulary checks for promotional, prohibited, and spam phrasing are English-only, so for other languages treat those three rows as "not checked" rather than "passed".

Can I embed this checker on my site?

Yes — free. Copy the iframe snippet from the embed section below. The embedded version drops Chatbotscape navigation and keeps the checker plus the attribution badge.

About this tool

Built and maintained by the Chatbotscape editorial team. The checks encode Meta's publicly documented template guidelines and rejection reasons — the same rules we walk through when we QA-test the platforms we review on WhatsApp, including SendPulse and Manychat. The lint is deterministic, with no AI and no network calls, and it errs conservative: it flags what the documentation says gets rejected, and it does not pretend to simulate Meta's private classifiers. Hit a rejection reason it missed? Email corrections@chatbotscape.com and we will fold it into the next revision.
