Wait — do I need a separate “Mailchimp integration” in RevSquared?

No. RevSquared has one generic Zapier integration. You paste one Catch Hook URL into it and you're done on the RevSquared side. The Mailchimp part lives entirely inside the Zap you build in Zapier.

Do I need a Zapier or n8n account?

Yes. Zapier's free tier covers ~100 tasks/mo. n8n is open-source and free to self-host.

Can I trigger Customer Journeys from call data?

Yes — most teams tag the subscriber with a tag that's wired to a Customer Journey trigger, or use Mailchimp's API for direct journey entry.

What does the webhook payload look like?

Full call JSON: caller name, phone, email, transcript, AI summary, sentiment, outcome, captured custom fields, recording URL.

Can I customize what data goes where?

Yes — inside Zapier you map any field from the webhook payload to any Mailchimp merge field or tag with point-and-click.

Common workflows

Build the Zaps your audience needs.

One webhook out of RevSquared, then any number of Zaps that route it into Mailchimp.

New caller

Mailchimp subscriber + tag

Caller info creates a Mailchimp subscriber in the right audience and adds a call-source tag.

Qualified lead

Trigger journey

High-intent calls drop the contact into your nurture journey the moment the call wraps.

Booking call

Welcome email

Booked appointments trigger a Mailchimp confirmation or welcome email.

Tag by topic

Update tags

Use call topic to tag the subscriber so segmentation stays sharp.

How to connect

One webhook. Any Zap you want.

Connect Zapier once in RevSquared. From then on every call posts a full JSON payload.

01
Start a Zap with Catch Hook
In Zapier, create a new Zap. Pick “Webhooks by Zapier” → “Catch Hook”. Copy the URL.
02
Paste it into RevSquared once
Open the Zapier integration in your RevSquared dashboard and paste the URL.
03
Fire a test call
Make a test call. Zapier receives the JSON and shows you the structure to map.
04
Add Mailchimp as the action
Add Mailchimp as the next step. Pick an action (Add/Update Subscriber, Add/Remove Tag, Send Transactional Email). Map the fields and turn it on.

Why teams pick RevSquared for Mailchimp

The honest way to wire RevSquared into your Mailchimp audience.

1 hookup

Connect once

RevSquared has one Zapier integration. Paste one Catch Hook URL and every call posts to it forever.

Many Zaps

Route however

From that webhook, add subscribers, tag, trigger journeys, send transactional — same payload, different Mailchimp actions.

Real-time

Not batched

The webhook fires seconds after the call ends. Your Mailchimp journeys start the same hour the call happens.
