Netlify has introduced a new Zapier integration in beta, allowing users to connect their forms or deploy notifications to hundreds of external services such as MailChimp, Hipchat, Google Docs, and more. This enables users to set up notifications for specific events, like form submissions or deployment completion, which can be sent via email, Slack, or other platforms. The integration is easily accessible through the Netlify beta invitation page, where users can learn more about Zapier and start creating their own custom integrations with Netlify.
