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 Page
Log in to LeadsNotify. Open Connectors in the top menu and choose Linkedin. Click Connect To Linkedin, sign in, tick the Pages you run lead gen form campaigns from, and approve the permissions LinkedIn asks for.
Every Page you ticked shows as CONNECTED. Adding another Page later? Click Connect To Linkedin again and tick the new Page, leaving the connected Pages ticked. Already connected? Skip to step 2.
Step 2: Create a Mailchimp Notifier
Go back to the dashboard. Under Create a new notifier, make sure the LinkedIn tab is selected, type “mailchimp” in the search box, find Send leads to Mailchimp and click Create notifier.
Step 3: Pick Your Page and Lead Gen Forms
The Create Notifier screen has two sides. The Trigger on the left is where leads come from. The Action on the right is where they go.
In the Trigger panel, choose your LinkedIn Page under Select Page, then pick one or more lead gen forms under Select Form. LeadsNotify then lists 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 4: Connect Mailchimp
The Action panel asks for your Mailchimp API Key and Server Prefix. These let LeadsNotify add leads to your Mailchimp account.
Where to find your Mailchimp API Key and Server Prefix
- 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 Server Prefix 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 the values into LeadsNotify and click Submit.
Step 5: Choose Where Leads Go, Then Submit
After you click Submit, LeadsNotify loads your Mailchimp audiences under Select Audience. Choose the audience new leads should join, then match the form fields to Mailchimp merge fields.
Tick Email me when a lead fails so you hear about it if a lead can’t be delivered, then click Submit. Your notifier appears under My Notifier, and the green switch means it’s live.
Step 6: Send a Test Lead and Check Lead Delivery
After you submit the notifier, LeadsNotify offers to send a test lead through it. You can also do this later: open My Notifier, click Edit on the notifier, then click TEST NOTIFIER.
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.
Want to test with a submission from LinkedIn itself? In Campaign Manager, open your ad account, go to Content & Assets > Lead generation forms, click More next to the form and choose Send Test Lead. Use a real email address you own.
Then open Lead Delivery in LeadsNotify. Every attempt is listed with the Page, the form, the destination and a status of Delivered or Failed, and the Response column shows the exact reply from Mailchimp. 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 Response column in Lead Delivery. It shows the exact reason Mailchimp gave for a failed lead.
| What you see | Likely cause | Fix |
|---|---|---|
| No leads arriving at all | The LinkedIn Page shows DISCONNECTED, often after an admin role changes | Connectors > Linkedin > Connect To Linkedin, and tick the Page again |
| Your form isn’t in Select Form | 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 and read the Response column for the reason |
