Mailjet is an email platform for marketing campaigns and transactional email, with contact lists and automation. If you run LinkedIn Lead Gen Forms, sending every new lead to Mailjet 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 Mailjet with LeadsNotify: connect your LinkedIn Page, connect Mailjet, choose where leads go, and test it. It takes about five minutes.
Why Send LinkedIn Leads to Mailjet?
Adding leads to a Mailjet contact list the moment they submit means your welcome email, or your next campaign, reaches them while they still remember your ad.
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 Mailjet (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 Mailjet 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 Mailjet as the Destination
Click Choose destination, find Mailjet in the list (you can search for it) and click the button to connect it.
Step 4: Connect Mailjet
The Connect step asks for your Mailjet API ID and API Secret. These let LeadsNotify add leads to your Mailjet account.
Where to find your Mailjet API ID and API Secret
- Log in to Mailjet.
- Open Account settings.
- Go to API Key Management (Primary and Subaccount).
- Copy the API Key into the API ID field in LeadsNotify, and the Secret Key into the API Secret field.
Mailjet only shows the Secret Key once, when it is created. If you do not have it saved, you can generate a new key pair, but be aware that resetting a Secret Key breaks any other tool already using it. Each Mailjet subaccount has its own key pair, so use the one for the account that holds your list.
Paste the values into LeadsNotify and click Submit.
Step 5: Match Your Fields and Save
After you click Submit, LeadsNotify connects to Mailjet and loads your contact lists. Choose the list new leads should join and match the form fields to Mailjet contact properties.
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 Contacts in Mailjet, open the list you chose 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 Mailjet
- LeadsNotify labels the fields API ID and API Secret. They are the Mailjet API Key and Secret Key.
- Create Mailjet contact properties for any extra form answers you want to use in emails.
- Pair the list with a Mailjet automation so each new contact gets a welcome email.
Troubleshooting the LinkedIn Lead Gen Forms to Mailjet 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 |
| Mailjet rejects the credentials | The Secret Key was reset, or the key belongs to a different subaccount | Use the key pair for the subaccount that holds your list |
| Another tool stopped sending after setup | The Secret Key was regenerated | Update the other tool with the new key, or create a separate subaccount key |
| A delivery shows Failed | Mailjet refused the lead | Open Lead delivery to find the lead, and read the reason in the failure alert email |
