Zendesk integration - Automatically blocklist unhappy customers from your marketing emails


The Sendinblue integration with Zendesk allows you to import your Zendesk contacts with open tickets to an exclusion list in Sendinblue in real-time. This allows you to blocklist clients who opened a ticket on Zendesk from marketing emails to avoid sending them marketing emails when they are not happy with your products. Once their ticket is resolved, your client will automatically be removed from the exclusion list and will receive your marketing emails again. 

❗️ Important
All the contacts from all the Zendesk users registered with the same instance will be imported to Sendinblue. Only contacts with an open ticket are imported (New, Open, Pending).

Before you start

  • You must be an admin of the Zendesk workspace or an agent with a custom role with special permission to manage the API access and be able to access the Apps and integrations section in Zendesk.

Part 1: Authorize Sendinblue to access your Zendesk Support account

Before you set up the Zendesk contacts integration, authorize Sendinblue to access your Zendesk Support account: 

  1. From your Agents' workspace/Dashboard, click  app-zendesk.png > Admin center
  2. From the left panel, click Apps and integrations > Zendesk API.
  3. Toggle the Password access option to enable the API authentication by login. 

You can now set up the Zendesk integration with Sendinblue 👇.

    • In the Select a list tab, select the list from your existing ones in which you want to synchronize your Zendesk contacts.

Part 3: Check your contacts

Now that your integration is connected to Sendinblue and set up, each time a client creates a Zendesk ticket on your website and if they are already registered in your Sendinblue contacts, they will be imported to your exclusion list selected during the Zendesk contacts set up

To access the list, go to Contacts > Lists and choose the folder in which you created it. You will see that your clients' details have been added to the list of contacts you selected during the Zendesk contacts set up:
