Mailchimp update existing subscriber

Hello I have a question about my mailchimp setting.

I have set the following steps in pabbly connect:

1) Mail Parser
I am sending an email (with JSON formatted data) to my Pabbly after a form is submitted on my site. The data will be added to custom fields in mailchimp

2) JSON Extrator
I am extracting the reveiced data. To split all the received date in different fields.

3) Mailchimp Add new Member with custom Fields
I am adding the person to my mailchimp list.

But currently if the person already is subscribed i am receiving a error email of pabbly.
How can i solve this, i tried different approaches but don't really know how i can fix this.

What i whan't is to add a check if they are already subscribed.
a) if allready subscribed do nothing
b) if not dubscribed add to mailchimp list

Kind regards,

Robin Bruinsma

Hey @nibz,

Thank you for reaching out.

To avoid this issue, you can first check whether the subscriber already exists in Mailchimp before adding them.

Here’s how you can do it:

1. Add the “Find Member” action in Mailchimp and search using the email address
2. This action will return a field called “Exact Matches Total Items”, which indicates how many matching records were found
3. Add a Filter step right after this action
4. Set the condition as:
   
   • Exact Matches Total Items = 0

     

• If the value is 0 → the user does not exist → the Add Member action will run
• If the value is greater than 0 → the user already exists → the workflow will skip adding them

Let us know if you need help setting this up.
