Every ad click lands in WhatsApp — greet it instantly, close it in the inbox.

A Facebook or Instagram ad that opens a WhatsApp chat with your business when someone taps it, instead of opening a website or a lead form. Meta calls them "Ads that Click to WhatsApp" (CTWA). The user lands in WhatsApp with a pre-filled message, and the conversation starts when they send it. Meta funds the first 72 hours of that conversation as long as you reply within the 24-hour service window.

Yes — this is the core of what WhatsMark does for ad leads. The bot-flow builder can trigger on a contact's first inbound message and run the flow you've designed: greeting, quick-reply qualifying questions, a catalogue link, an agent handoff. Because the reply is instant, you stay inside Meta's 24-hour service rule, which keeps the ads-driven free-conversation window open. One note for accuracy: the flow greets every new inbound lead — it isn't specific to a particular ad or campaign, and it can't branch on which creative the lead came from.

Not in the app today — and we'd rather say that plainly than imply a feature that isn't there. When a lead arrives from a CTWA ad, Meta sends a referral payload with the first message, and WhatsMark does receive it. But we don't currently surface it as a contact field, a filter, an export column, or an attribution report — so per-ad attribution and ROAS reporting should be done in Meta Ads Manager for now. What WhatsMark guarantees is that the lead is answered instantly and handled properly in your team inbox. In-app ad attribution reporting is on the roadmap, not in the product at the moment.

No, not today. WhatsMark does not currently post conversion events to Meta's Conversions API (CAPI) or fire a Facebook Pixel from the WhatsApp conversation, so Meta optimises delivery on its own click and conversation-start signals rather than on a downstream 'qualified' or 'purchased' event from us. If closed-loop conversion optimization is essential to your media buying, plan around that limitation for now. It is a roadmap item, not a shipped capability.

Two layers. Layer one is Meta's ad cost — the bid you set in Ads Manager, charged as CPC or CPM like any Meta ad. Layer two is the per-conversation marketing fee Meta charges for the chat itself, billed against your own connected WhatsApp Business Account. WhatsMark adds 0% on layer two — you connect your own WABA, so that fee never passes through us to be marked up. CTWA conversations are also free for 72 hours after the first message as long as you reply within 24 hours, so a fast welcome bot keeps the cost lower than a cold, slow-answered chat.

Click-to-Messenger opens Facebook Messenger; CTWA opens WhatsApp. Different surface, different audience, different reply window. CTWA tends to win where your buyers already live on WhatsApp daily (India, LATAM, MEA, SEA) and where the sales motion benefits from voice notes, contact share, catalogue browsing, and document attachments. WhatsMark handles both — Messenger conversations land in the same shared inbox as WhatsApp — so you're not locked to one surface.

Yes — CTWA ads go through the same Meta ad-review process as any Facebook or Instagram ad. The pre-filled message text has to follow Meta's ad policies (no prohibited content, no misleading claims). Once your WhatsApp Business Account is connected to your Facebook Page or Business Manager, the destination is set; approval depends on the creative, not the brand size. WhatsMark doesn't add an extra review layer — the only gate is Meta's.

You can run each client as its own WhatsMark workspace, and the Reseller plan tier gives you the higher limits (unlimited numbers, staff, campaigns) to do that at scale. To be straight about it: a single master account that creates and manages isolated client sub-tenants, with per-client attribution and an agency rollup dashboard, is not built yet — that's on the B2B roadmap, not shipped today. For now, one workspace per client is the honest, working answer, and the founding Reseller pricing is on the /reseller page.
