Mailchimp is one of the most widely used email marketing platforms, organised around audiences, tags and automated customer journeys. If you run LinkedIn Lead Gen Forms, sending every new lead to Mailchimp automatically saves you downloading files from Campaign Manager and importing them by hand.
This guide shows you how to send LinkedIn Lead Gen Forms to Mailchimp with LeadsNotify: connect your LinkedIn Page, connect Mailchimp, choose where leads go, and test it. It takes about five minutes.
Why Send LinkedIn Leads to Mailchimp?
Mailchimp customer journeys start when a contact joins an audience or gets a tag. Adding ad leads automatically starts that journey while the lead is still interested.
LinkedIn leads are often your most valuable leads: decision makers, with company and job title already filled in from their profile. They are also the easiest to lose, because they wait in Campaign Manager until someone remembers to download them.
How to Send LinkedIn Lead Gen Forms to Mailchimp (About 5 Minutes)
Before you start, you need: a LeadsNotify account on any plan, free included, admin access to the LinkedIn Page that runs your lead gen forms, and your Mailchimp account and permission to create API keys.
Step 1: Connect Your LinkedIn Account
Log in to LeadsNotify and open Lead sources. Click Sign in with LinkedIn, sign in, and approve the permissions LinkedIn asks for. Your account shows as Connected under LinkedIn accounts. Already connected? Skip to step 2.
Step 2: Create a Notifier and Pick Your Lead Gen Forms
Click Create notifier. In the Source step, choose LinkedIn Lead Gen Forms, select your LinkedIn account and tick one or more lead gen forms. LeadsNotify reads the fields on those forms, such as first name, last name, email, company name and job title.
Only active forms are shown. If a form is missing, check that the form and its campaign are active in Campaign Manager.
Step 3: Choose Mailchimp as the Destination
Click Choose destination, find Mailchimp in the list (you can search for it) and click the button to connect it.
Step 4: Connect Mailchimp
The Connect step asks for your Mailchimp API key and your Data center, which Mailchimp also calls the server prefix. These let LeadsNotify add leads to your Mailchimp account.
Where to find your Mailchimp API key and data center
- Log in to Mailchimp.
- Click your profile icon and choose Profile.
- Open the Extras menu and choose API keys.
- Click Create A Key, name it LeadsNotify, click Generate Key and copy it.
- Your Data center is the part after the last hyphen at the end of the key, such as
us6. You can also see it at the start of the Mailchimp web address when you are logged in.
Mailchimp shows the full key only once. New Mailchimp API keys also expire after a year, so set a reminder to replace it.
Paste both values into LeadsNotify and click Connect Mailchimp.
Step 5: Match Your Fields and Save
After you connect, LeadsNotify loads your Mailchimp audiences. Choose the audience new leads should join, then match the form fields to Mailchimp merge fields.
Save the notifier. It appears under Notifiers, and the green switch means it’s live. The test step shows whether failure alerts are on, so you hear about it if a lead can’t be delivered.
Step 6: Send a Test Lead and Check Lead delivery
Saving the notifier opens Review and test delivery. LeadsNotify cannot create LinkedIn test leads itself, but LinkedIn can, and the test step lists the exact steps for your form.
To send one, open LinkedIn Campaign Manager and choose your ad account, go to Content & Assets > Lead generation forms, click More next to the form and choose Send Test Lead. Fill in a first name, last name and email address you own, then click Send. Later, the ⋯ menu next to the notifier in Notifiers has How to send a test lead with the same steps.
Open Audience > All contacts in Mailchimp and search for the test lead. If the test lead is there with the right details, the notifier is working.
Then open Lead delivery in LeadsNotify. Every attempt is listed with the source, the destination, a status of Delivered or Failed and the delivery time. Our guide to the lead delivery status dashboard walks through every column.
Tips for Getting More From LinkedIn Leads in Mailchimp
- Use a tag in Mailchimp to mark ad leads and start a customer journey from it.
- If your audience uses double opt-in, the contact shows as pending until they confirm.
Troubleshooting the LinkedIn Lead Gen Forms to Mailchimp Integration
Start with the Lead delivery page. It shows whether each lead was Delivered or Failed, and the failure alert email includes the reason.
| What you see | Likely cause | Fix |
|---|---|---|
| No leads arriving at all | The LinkedIn account shows as disconnected, often after an admin role changes | Lead sources > Sign in with LinkedIn, and reconnect the account |
| Your form isn’t in the form list | Only active forms are shown | Check the form and campaign status in Campaign Manager, then reopen the notifier |
| Leads stopped after you edited the campaign | The campaign now uses a different lead gen form | Edit the notifier and select the new form |
| Mailchimp rejects the key | The server prefix does not match the key | Use the letters and number after the last hyphen of the key, such as us6 |
| Leads stopped after a year | The Mailchimp API key expired | Create a new key and edit the notifier |
| A delivery shows Failed | Mailchimp refused the lead | Open Lead delivery to find the lead, and read the reason in the failure alert email |
