How to process items in a list individually with Zapier?

Hey everyone! I’m trying to set up a Zap that gets a bunch of emails from an API and then adds each one to Mailchimp. The problem is, when I try to add the whole list at once, Mailchimp gets mad and says the email address isn’t valid.

I guess Mailchimp doesn’t like getting a bunch of emails all at once. So now I’m wondering if there’s a way to make Zapier go through the list and add each email one by one.

I was thinking it might work something like this:

for (let email of emailList) {
  addToMailchimp(email);
}

Is there any way to do this in Zapier? Maybe with a special action or some kind of script? I can’t use the command line, so it has to be something I can do right in Zapier.

Thanks for any help you can give me!

yo, i had the same issue! heres a quick fix: use ‘paths’ in zapier. set up diff paths for each email, then add the mailchimp action in each path. its not as fancy as looping but it works. just remember to test with a small batch first. good luck!

I’ve actually dealt with this exact problem in my work. The Looping by Zapier action is definitely the way to go, but there’s a trick to make it even more robust.

What I did was add an error handling step after the Mailchimp action inside the loop. This way, if one email fails (maybe it’s invalid), the whole Zap doesn’t crash. It just moves on to the next email.

Also, I found it helpful to add a delay of a few seconds between each iteration. This prevents overwhelming Mailchimp’s API with too many requests at once.

Lastly, consider setting up a separate Zap to notify you of any failed additions. This way, you can manually review and fix any problematic emails later. It’s saved me hours of troubleshooting in the long run.

I’ve encountered a similar issue before, and there’s actually a neat solution in Zapier for this. You’ll want to use the ‘Looping by Zapier’ action. It allows you to iterate through each item in a list individually.

Here’s how you can set it up:

  1. Start with your trigger that fetches the email list.
  2. Add a ‘Looping by Zapier’ step.
  3. Configure it to loop through your email list.
  4. Inside the loop, add your Mailchimp ‘Add/Update Subscriber’ action.

This way, Zapier will process each email one at a time, avoiding the bulk upload issue with Mailchimp. It’s more efficient than writing custom code and works seamlessly within Zapier’s interface. Just make sure to test it thoroughly with a small list first to ensure everything’s working as expected.
