SOLUTION: Mailchimp webhooks not working for imported contacts

Webhooks in Mailchimp API work perfectly fine most of the times but there is a small catch. If you import a bunch of subscribers to your list by importing a CSV file (or copy/paste etc.), then any webhooks registered on that particular list don’t fire.

But there is a workaround. You need to do the following:

  1. Create a new temporary list.
  2. Import your CSV file into that list.
  3. Then select the imported contacts on Mailchimp UI and move them into actual list on which you have registered webhooks.
  4. At that point, Mailchimp will dispatch any necessary webhooks for the contacts you have imported.

Did you ever run into this problem? If so, please give the above mentioned steps a go and let me know in comments if it worked for you or not.
