Click to WhatsApp Ads: the complete guide to acquiring leads in chat

Click to WhatsApp Ads (CTWA) are perhaps the ad format with the best return available today on Meta, yet they remain underused by businesses. Instead of sending the user to a landing page where they often bounce, the ad opens a conversation on WhatsApp directly: the contact enters the chat and you get a real lead to talk to. In this guide we look at how to set them up, which objective to choose, and how to measure results without burning through your budget.

What a click to WhatsApp Ad is

A click to WhatsApp Ad is a normal Facebook or Instagram ad with a call to action like "Send message". On click, no website opens, but rather the WhatsApp chat with your business, pre-filled with a first message. From there the conversation continues like any other chat, with the difference that you now have the number and implicit consent to reply within the 24-hour window.

The advantage is twofold: you reduce friction (no form to fill in) and capture the contact on a channel with very high open rates. For high-consideration sectors, such as services, real estate, automotive, or courses, this format often converts better than classic lead forms.

Why optimize for opt-in and not for the sale

The most common mistake is asking the algorithm to optimize immediately for the final conversion. At the start, sales data is too sparse for Meta to learn from. It's better to optimize for the start of the conversation, that is, for cost per opt-in: get as many people as possible into the chat at low cost, then it's your sales process (or the AI) that turns them into customers.

• Low, predictable cost per opt-in, ideal for scaling your budget with peace of mind
• Enough conversation volume to train the algorithm and your team
• Lead quality that can be improved downstream with qualifying questions in chat
• Real contact details (the number) that stay yours and can be reused in your CRM

How to set up the campaign step by step

Setup happens in Meta Business Manager, but the part that makes the difference is what happens after the click. Here is the essential flow.

1. Create the campaign in Ads Manager

Choose the "Engagement" or "Sales" objective and, as the message destination, select WhatsApp. Connect the WhatsApp Business number associated with your company.

2. Write the opening message

Pre-fill a clear first message that the user will send with a single tap, for example "Hi, I'd like information about...". This raises the response rate because the person doesn't have to think about what to write.

3. Prepare the automatic reply

This is where your WhatsApp management tool comes in. A trained AI agent can reply within seconds, 24 hours a day, qualify the lead with two or three questions, and hand the conversation over to an operator when needed. Replying immediately is decisive: a contact left waiting an hour goes cold.

With SendApp you can receive leads from click to WhatsApp Ads in a multichannel inbox, have them handled by the AI agent trained on your business, and save them automatically in the CRM with a campaign tag, so you can measure which ads actually bring in customers.

How to measure results

Don't stop at the cost per message in Ads Manager. The real indicator is the quality of the conversations. Tag incoming contacts with the campaign name and track how many turn into appointments or sales. Only this way do you understand your cost per qualified lead and the real return, not the apparent one.

How to do it with SendApp

SendApp connects your WhatsApp number (via official Meta API or via WhatsApp Web with a QR code) to the platform, so every lead that arrives from a click to WhatsApp Ad ends up in a single inbox. The AI agent replies instantly, qualifies, and hands over to an operator when needed; contacts are saved in the CRM with campaign tags and you can then work them with follow-ups and broadcasts. Plans start at 19 euros per month and WhatsApp Cloud API messages are billed directly by Meta, with no markup on our part. It's one of the platforms used by over 30,000 businesses.
