Connect Mailjet to Uplup

How to connect

1. Log in to your Uplup brand dashboard and open Integrations in the left sidebar.
2. Find Mailjet in the Email & CRM section and click Connect.
3. Paste your API Key + Secret Key. Account → REST API → API Key Management.
4. Click Fetch Lists to load your contact lists from Mailjet.
5. Pick the contact list you want new leads sent to.
6. Click Save. The integration is now active for every form and quiz in this brand.

What syncs to Mailjet

Email, firstname, lastname properties — added to the selected contact list via the managecontact endpoint (upserts + attaches in one call).

When does the lead get sent?

Every time someone submits one of your Uplup forms or completes one of your quizzes, the lead is pushed to Mailjet within a few seconds. This is fire-and-forget — submissions still succeed even if Mailjet is temporarily unreachable, and every attempt is logged on your account so you can audit what was sent.

Both forms and quizzes

This integration works identically for forms (where the user fills in name and email directly) and quizzes (where the user reaches the Lead Capture page after answering questions). Uplup picks up the email, name, and phone fields automatically — no per-form configuration needed.

Troubleshooting

• Fetch Lists returns an error. Double-check the API Key + Secret Key value. If you regenerated keys recently, the old ones stop working immediately.
• Submission succeeded but lead didn’t appear in Mailjet. Confirm the form has both an email field and (for quizzes) a Lead Capture page that collects email. Without an email field, there’s nothing to send.
• Want to send to a different contact list. Open the integration again, pick a new contact list, and save. The change applies to all future submissions.

Disconnecting

Open the Mailjet integration in your Uplup Integrations page and click Disconnect. New submissions stop being sent to Mailjet immediately. Submissions already sent stay in Mailjet until you delete them there.
