MailWizz setup

MailWizz is a self-hosted email marketing application. The AcquisitionSuite integration uses its API with signed requests, custom field mapping and optional double opt-in. Available on every plan.

What you need

• A running MailWizz installation reachable from your website
• An API key pair (public and private) created in MailWizz for your customer account
• The List UID of the list that should receive leads

Connecting

1. Go to AcquisitionSuite → Integrations and open the MailWizz panel.
2. Enter the API URL of your MailWizz API (the address of your installation’s API endpoint).
3. Enter your Public Key and Private Key.
4. Click Test connection, then Fetch Lists and pick your list (or paste its List UID).
5. Choose whether to Require email confirmation before subscribing.
6. Switch the integration on and save.

Custom field mapping

MailWizz lists can hold extra fields, each with a TAG. Under Custom Field Mapping, map AcquisitionSuite data (such as the lead’s phone, company or any form field) to your list’s field TAGs so that data lands in the right MailWizz column. Fields you leave unmapped are not sent.

Common problems

• Connection fails: check the API URL (including https), the keys, and that your MailWizz server allows API access from your website’s IP.
• Contacts missing: confirm the List UID and that double opt-in is not holding them as unconfirmed.
• Field not filled: the TAG in the mapping must exactly match the MailWizz field TAG.
