Google Contacts + Constant Contact + Google Sheets: When a new contact is added to Google Contacts, the automation checks if the contact already exists in Constant Contact. If not, it adds the contact to Constant Contact and then adds the contact's information to a Google Sheet for tracking subscription status.
Constant Contact + Google Contacts + Slack: When a new contact subscribes through Constant Contact, the automation finds the corresponding contact in Google Contacts and updates it with subscription information. Finally, a Slack message is sent to a designated channel notifying the team about the new subscription.
