Promotional messages are allowed on WhatsApp — as approved templates sent to opted-in customers. Templates get rejected for specific, fixable reasons:

Content

• Requesting sensitive data — never ask for full card numbers, financial account numbers, or government IDs (last-4 digits is acceptable).
• Policy violations — content must comply with WhatsApp's Commerce and Business policies (see restricted categories); no abusive or threatening wording.

Formatting

• Floating variables — a line that's only {{1}} with no surrounding text.
• Variables with special characters (#, $, %) or missing sample values.
• Emojis in the header, spelling/grammar errors, vague template names.
• Too generic — "Hello {{1}}, thanks!" gives reviewers nothing; include real transaction/promo context.
• Language mismatch — the selected language must match the text.
• Duplicate — same body+footer as an existing template.

SuperLemon validates most of this in real time before submission. Still rejected? Email support@superlemon.xyz with the template name.
