Pushbuild

Contacts in Google Sheets kept in step with Mailchimp, tags and unsubscribes included.

Leads, event sign-ups and customer lists often start in a Google Sheet, then get imported into Mailchimp by hand with a new CSV every time. A custom setup adds new rows as subscribers, updates changed details and tags, never re-subscribes someone who opted out, and writes campaign results back to the sheet. Every run is logged, and anything that cannot be matched is sent to you. We write down the scope and agree it with you before we start.

Start your integration

Sound familiar?

What businesses that keep contact lists in Google Sheets tell us before a project starts.

  • Contacts are imported by CSV every week.
  • Unsubscribed people get re-added.
  • Tags are applied by hand.
  • Duplicates pile up in the audience.
  • Nobody knows who opened the last campaign.

What we build

Each one is a working piece you can open and check when it's done.

Questions people ask first

Can it handle more than one sheet?

Yes, each sheet or tab can feed its own tags.

What about duplicates?

Contacts are matched by email, so each person appears once.

Will it email anyone automatically?

Only if you set up a Mailchimp automation for the tag.

Want this as a ready-made pack?

We are turning the most requested integrations into ready-made n8n workflows you import and run in your own accounts. Tell us you want this one and we will email you when it is ready.
