Connect Google Calendar to Mailchimp — No Code Required
Automate the handoff between Google Calendar and Mailchimp using plain English. Describe what you want to happen and Vendarwon Flow builds and runs the workflow automatically — forever, in real time, without developer help.
Why teams connect Google Calendar to Mailchimp
Most teams use Google Calendar and Mailchimp as separate tools — which means important data created in one never reaches the other unless someone manually transfers it. Connecting them with Vendarwon Flow eliminates that handoff entirely: the moment something happens in Google Calendar, the right action fires in Mailchimp automatically, every time.
New customers from Shopify, form submissions, and CRM contacts flow straight into the right Mailchimp list
Subscribers are automatically tagged based on their source, purchase history, or behaviour in other tools
List segments stay accurate in real time — no manual imports, no stale contacts, no missed opportunities
What you can automate between Google Calendar and Mailchimp
When a new event arrives in Google Calendar, automatically add a subscriber to a list in Mailchimp — no manual work, no delay
Route specific Google Calendar events from key sources and tag a subscriber in Mailchimp the moment they arrive
Build a scheduled digest: collect Google Calendar activity over time and remove a subscriber from a list in Mailchimp on a daily or weekly schedule
When a high-priority event is detected in Google Calendar, trigger an email automation in Mailchimp with all the relevant context included
Filter Google Calendar events by keyword, sender, or category — then add a subscriber to a list in Mailchimp only for the ones that matter
Create a two-way feedback loop: every qualifying event in Google Calendar triggers a record in Mailchimp that your team can track and act on
What you stop doing manually
Google Calendar is valuable — but without automation, it creates repetitive manual work. Here is what teams eliminate the moment they connect Google Calendar to Mailchimp:
Creating calendar events manually after every booked meeting, new deal, or deadline added elsewhere
Sending reminder emails or Slack messages for upcoming events by hand each time
Copying event details from emails or forms into Google Calendar one entry at a time

Frequently asked questions
Does Google Calendar have a native Mailchimp integration?
Google Calendar and Mailchimp do not have a built-in direct integration that covers most real automation scenarios. Vendarwon Flow acts as the bridge — you describe what you want in plain English and it handles the API connections between both tools securely. No Zapier account, no developer, no webhook configuration needed.
What Google Calendar events can trigger the automation?
With Vendarwon Flow you can trigger automation from any of these Google Calendar events: New calendar event created; event starting soon; event cancelled or updated. You can also combine triggers — for example, only fire the automation when a event matches a specific keyword or comes from a particular source.
What can the automation do inside Mailchimp?
Once triggered, the workflow can perform any of these actions in Mailchimp: Add a subscriber to a list; tag a subscriber; remove a subscriber from a list; trigger an email automation. You can chain multiple actions together — for example, add a subscriber to a list and then tag a subscriber.
How quickly does the automation run after something happens in Google Calendar?
In real time — typically within a few seconds of the triggering event. Vendarwon Flow runs continuously in the cloud, so there is no polling delay. The moment a new event meets your conditions in Google Calendar, the workflow fires and the action in Mailchimp happens instantly, whether it is 2 PM or 2 AM.
Can I add conditions so only certain events trigger the automation?
Yes — conditional logic is built in. You can describe rules like "only trigger when the event contains the word urgent" or "skip if the source is internal." Vendarwon Flow supports AND/OR conditions, keyword matching, and value comparisons, all configured in plain English without writing any code or building separate logic branches.
