Setup

Connect it in a few steps.

Set up with Zapier

1
Set the trigger. Create a Zap with Mailchimp as the trigger app and "New subscriber" as the event. Connect your account.
2
Add the API action. Add APIVerve as the action, select the Antonym API, and map your trigger data to the request.
3
Send it back. Add a second Mailchimp action for "Add subscriber" and map the returned fields (like word) into it.
4
Test & turn on. Test the Zap with real data to confirm the mapping, then turn it on.

Set up with Make

1
Add the trigger. Create a scenario and add a Mailchimp module set to "New subscriber". Authenticate your account.
2
Call the API. Add an HTTP module pointing at api.apiverve.com/v1/antonym with your x-api-key header. Pass the trigger's data as the input.
3
Parse & map. Add a JSON module to read the response, then a Mailchimp module for "Add subscriber". Map fields like data.word into place.
4
Activate. Run once to confirm the mapping, then switch the scenario on and set its schedule.

Set up with n8n

1
Add the trigger node. Start a workflow with a Mailchimp trigger node for "New subscriber" and connect your credentials.
2
Add an HTTP Request node. Point it at api.apiverve.com/v1/antonym using Header Auth (x-api-key). Feed in the trigger data.
3
Map with expressions. Add a Mailchimp node for "Add subscriber" and reference the response with expressions such as {{ $json.data.word }}.
4
Execute & activate. Execute manually to verify, then activate the workflow for production.

Mailchimp + Antonym API FAQ

How do I clean my Mailchimp list with an email validation API?

Export your list, run emails through a validation API using an automation workflow, then update subscriber tags or remove invalid addresses. Or set up real-time validation for new signups.

Can I prevent invalid emails from being added to Mailchimp?

Yes. Instead of connecting forms directly to Mailchimp, route them through an automation that validates emails first. Only add subscribers who pass validation.

How does email validation improve my Mailchimp deliverability?

Removing invalid, disposable, and risky emails reduces bounce rates, protects your sender reputation, and improves inbox placement for your campaigns.
