Step 1: Integrate Your MailChimp Account

First grab your MailChimp API key.


This is found in the MailChimp “Account > Extras > API Keys”

Then Create a New API Key or copy an existing API key.

Go to your Call Loop “Account > Integrations” then connect your app.

and save the settings to connect your MailChimp account to Call Loop.

Step 2: Integrate Your MailChimp Account

Create your group where you want to add people after they optin. You do not need to integrate with MailChimp here as we will integrate on the actual Message

Step 3: Create Your Followup

You will need to create an immediate followup. This immediate message will be delivered to your contact right after they join your group.

On the 2nd step, you will select SMS and create your message which may ask for the field like email address.

“Thanks for registering. To confirm, please reply with your email address.”

Step 4: Save and Turn Your Followup On

After you save, you need to turn on your Followup in order to test it.

Step 5: Connect Your Keyword

Head over to “Keywords” at the top and make sure that you connect the keyword to your new group.

You can purchase a keyword for just $10/mo or $97/year or use a keyword credit, if you have a subscription plan.

Step 6: Test it!

To test this,  text {your keyword} to 38470 and you should get your followup campaign and see that you are being added to Call Loop as well as your MailChimp list.


You can collect this information from Broadcasts too! So if you currently have a SMs list, send out a Broadcast message requesting their email address to start building your email list with MailChimp.
