Email Platform Not Receiving Quiz Leads

If your email marketing platform is connected to Quizify but contacts are not appearing after quiz submissions, this guide covers the most common causes specific to email platform integrations.

Most Common Cause: Email Field Not Enabled

Quizify cannot create a contact in your email platform without an email address. If the email field is not enabled in the user information form — or if the form itself is not enabled — no contacts will ever sync.

Check:

Open the quiz in Quizify
Go to User Info Form settings
Confirm the form is enabled
Confirm the email field is added to the form

This single issue accounts for the majority of "no leads in email platform" reports.

Step 2: API Key Invalid or Entered Incorrectly

An incorrect, outdated, or recently regenerated API key will prevent the sync.

Go to Integrations in Quizify and open your email platform settings
Note the API key currently saved
Log in to your email platform and generate a new API key
Paste the new key into Quizify and save
Complete a test submission to verify

Step 3: Wrong List or Audience Selected

If you have multiple lists or audiences in your email platform, check that the correct one is selected in the Quizify integration settings.

Contacts may be arriving in a different list than expected, making it appear as though the sync is not working.

Step 4: Contact Has a Conflicting Status

Some email platforms will not update or add a contact if they have a specific status that prevents it:

Mailchimp: If a contact is unsubscribed in Mailchimp, Quizify will not resubscribe them automatically. The contact exists but is not mailable.

Klaviyo: If a profile already exists with a suppressed status, quiz data may update the profile properties but not change the subscription status.

Active Campaign: If a contact has been explicitly unsubscribed or blocked, they may not be updated.

Check the specific contact's status in your email platform to see if this applies.

Platform-Specific Notes

Mailchimp

Ensure the audience selected in Quizify matches the intended audience
Check whether double opt-in is enabled on the audience — if it is, contacts appear as "pending" until they confirm their email
Unsubscribed contacts will not be resubscribed automatically

Klaviyo

Ensure you are using a private API key (not the public key)
Answer tags sync as profile properties — check the contact's profile properties, not just their list membership
If the contact already exists, check whether quiz data updated their profile

Brevo (Sendinblue)

Ensure the API key has write access to contacts
Contacts may have a "Blacklisted" status in Brevo that prevents updates

Active Campaign

Both the API key and the API URL are required — check that both are entered correctly
The API URL should include your account subdomain (e.g., youraccountname.activehosted.com)

Omnisend

Confirm the API key is the correct type with contact write permissions

Frequently asked questions

A customer's email already exists in Mailchimp but their quiz data didn't update.

Check whether the contact is in an unsubscribed status in Mailchimp. Quizify will not update unsubscribed contacts. If the contact is subscribed and still not updating, confirm the API key is valid and retry a test submission with that email address.

How do I reconnect my email platform integration?

Go to Integrations in Quizify, find your email platform, and click Disconnect or Remove. Then reconnect by entering a fresh API key and selecting the correct audience or list. Save and complete a test submission to verify.

I connected Mailchimp but leads are not appearing in my audience.

The most common cause is the email field not being enabled in the user information form. Check this first. Then verify the API key is current, and that the correct Mailchimp audience is selected. Also check whether double opt-in is enabled on the audience — new contacts will appear as "pending" until they confirm.

I connected the integration but the email field was not enabled — will past submissions sync?

No. Quizify only syncs data at the time of submission. Past submissions that occurred before the email field was enabled cannot be retroactively synced. To capture these leads, you would need to manually export them from the Quizify submissions dashboard and import them into your email platform.

Klaviyo is connected but no contacts are being created after quiz submissions.

Confirm you are using the Klaviyo private API key (not the public key). Check the email field is enabled in the user info form. If the contacts exist in Klaviyo from before, check their profile — quiz data may be updating profile properties rather than creating a new record.
