Add WhatsApp Subscribers to Campaign Monitor with Consent

By Alva Chew 4 min read Updated November 7, 2026

This recipe adds people who agree in chat to your Campaign Monitor list, with a record of their consent and what they are interested in. Part of connecting Campaign Monitor to WhatsApp and AI chat.

What happens today

Customers ask about an event, a launch or the next sale on WhatsApp and Instagram, and say they want to hear about it. The person replying means to add them to Campaign Monitor later. Some get added without a record of how they agreed, some get added twice, and many never get added. The interest they mentioned is lost.

The flow that works

  1. AeroChat answers the customer’s question first.
  2. It asks whether they want to hear from you by email, and says what they will get.
  3. Only after a clear yes, it asks for their email if it does not have it.
  4. It looks them up in Campaign Monitor, so a returning subscriber is updated instead of added twice.
  5. It adds or updates them and records the channel, the date and what they asked about.
  6. If they say no, it carries on helping and adds nothing.

The recipe

Copy this into AeroChat

When someone asks about our products, offers or upcoming launches, answer their question first from our knowledge base. Then follow these steps.

  1. If they show interest in future offers, launches or news, ask: “Would you like us to email you about this and other offers? You can unsubscribe at any time.”
  2. Only if they clearly say yes, ask for their email if we do not have it.
  3. Look up that email on our Newsletter list (example) in Campaign Monitor.
  4. Add or update the subscriber with their name and email.
  5. Set the custom field Source to Chat and the custom field Interest to what they asked about, such as Gift sets (example values).
  6. Set the custom field Chat consent to “Agreed to marketing emails in chat on [date] via [channel]” (example).
  7. Confirm to them that they are signed up and what they will receive.

Never add anyone who has not said yes in this conversation. If they say no or do not answer, carry on helping and do not ask again. Reply in the customer’s language.

Change the example names and values to the ones your Campaign Monitor account uses before you paste it.

What to connect

  • Campaign Monitor. An administrator opens Account Settings, API keys in Campaign Monitor and copies the API key, the client ID and the IDs of the lists you use. Paste them in when AeroChat asks.
  • Your knowledge base. Upload your product or service details to AeroChat so it can answer before it asks.

After you paste the recipe, AeroChat builds the workflow as a draft and shows a checklist: connect Campaign Monitor, add your knowledge base if the recipe uses one, then switch it on. If it built the connection from Campaign Monitor’s public documentation, the checklist asks you to check it once against the current docs.

Using a different system? If it has a public API, it connects to AeroChat the same way: describe what you want, paste in its key, and it runs.

What you still decide

  • The wording of the consent question and what you promise to send.
  • Which list new subscribers join, and which tags or fields AeroChat sets.
  • Whether new subscribers confirm by email first, which you set on the list in Campaign Monitor.

The result to expect

Every chat contact who wants your emails is in Campaign Monitor with a record of when and where they agreed, and what they asked about. Your campaigns reach people who asked for them, and nobody is added without saying yes.

Measure it with your own numbers: subscribers added from chat, and their open and click rates, for a month before and after.

Next: answer subscription questions and unsubscribe on request.

Works on every chat channel

This workflow runs the same way on WhatsApp, Instagram, Facebook Messenger, TikTok, Telegram, the chat on your website and email, with the same Campaign Monitor connection behind it. See what each channel does on the Campaign Monitor integration page.
