WhatsApp campaigns that get read — without the markup that ate your last platform's margin.

Yes — when you use the official WhatsApp Business Cloud API and the recipient has explicitly opted in to receive marketing messages. Marketing-class broadcasts to people who haven't opted in violate Meta policy and can get your number throttled or blocked. WhatsMark captures opt-in consent at every entry point (Shopify checkout, click-to-WhatsApp ad, signup form) and tracks consent against every contact, so you always know who you can broadcast to and who you can't.

No — 0%. WhatsMark charges only the platform subscription. Meta's per-conversation fees are billed directly to your Meta Business Account at Meta's published rates, so you can see them on your own Meta invoice rather than ours. If you are comparing platforms, check whether they let Meta bill you or sell you credits at their own rate card — that is where the difference hides.

Templates submit through WhatsMark to Meta's review queue and typically come back in minutes (sometimes hours for content that requires manual review). Common rejection reasons: vague placeholders, content that looks promotional but lacks an unsubscribe path, mismatched language tags. WhatsMark's template builder validates against Meta's rules before submission and flags issues in advance.

Meta operates a tier-based throughput cap: Tier 1 = 1,000 unique recipients/day, Tier 2 = 10,000, Tier 3 = 100,000, Tier 4 = unlimited. Your tier moves up automatically as your sender quality stays "high" — clean opt-in, low spam-flag rate, low template-rejection rate. WhatsMark monitors your quality rating in real time and throttles broadcasts when quality dips, before Meta enforces.

You connect your Shopify or WooCommerce store from settings; the store tells WhatsMark when a checkout is abandoned, and the pre-built Cart Recovery flow fires a templated WhatsApp nudge with timed follow-up steps, stopping the moment the order completes. Two caveats: WhatsMark can only message the shopper if the store captured their phone at checkout, and it's one store per workspace today (any other platform connects through our REST API).

You can connect up to 2 WhatsApp numbers on Free, 10 on Professional, and unlimited on Reseller, and keep each brand's contacts in its own Groups and team inbox. Being clear about today: these run in one workspace with shared reporting, not fully isolated white-label sub-accounts per client — that broader reseller capability is on the roadmap, not shipped.

WhatsApp opens at ~98% within minutes; email at ~18% within hours; SMS at ~75% but is one-way and lacks rich media. WhatsApp supports two-way conversations, buttons, images, PDF attachments, and structured templates. The cost-per-impression on WhatsApp is higher than SMS on a unit basis, but the conversion uplift more than compensates for most marketing budgets.

Numbers get rate-limited or blocked when too many recipients mark messages as spam, when content fails template review repeatedly, or when send patterns look suspicious. WhatsMark monitors your quality rating in real time, throttles broadcasts when quality drops, and surfaces actionable alerts before Meta enforces. We also coach you on the most common policy mistakes (sending without opt-in, over-sending in 24-hour windows, mismatched template content).

In three places, and together they're what make WhatsApp marketing outperform a blast. First, automation runs the campaign without you: a drip sequence fires on a trigger (cart abandoned, signed up, 60 days since last order), personalises each message from your contact data, and stops the moment someone converts — so nobody gets a nudge for something they already bought. Second, AI helps you write — drafting and tightening template copy and offer lines so you ship variants faster. Third, when a broadcast sparks a reply, an AI flow can field the routine follow-ups ("is the offer still on?", "how do I redeem this?") instead of letting interested buyers sit unanswered. The result is campaigns that reach people on a channel they actually open (~98%) and keep the conversation going automatically — which is exactly why WhatsApp conversion runs several times higher than email.
