Connect Mailchimp to Google AlloyDB — Email Data on Google Cloud

Log into the Supermetrics Hub, create a new data transfer, select Mailchimp as the source and AlloyDB as the destination. Authorize your Mailchimp account, provide your AlloyDB connection details, choose the fields you want, set a schedule, and start the transfer. No custom ETL pipelines or Cloud Dataflow jobs required — Supermetrics creates and manages the tables automatically using standard PostgreSQL-compatible commands, so any tool or library that works with PostgreSQL works with your marketing data out of the box.

Supermetrics is SOC 2 Type II certified and fully GDPR compliant. All Mailchimp credentials are encrypted at rest and in transit. Data flows directly from the Mailchimp API to your own AlloyDB instance — Supermetrics does not store your marketing data on its servers. AlloyDB runs inside your Google Cloud VPC, so traffic never traverses the public internet. Google Cloud IAM policies control who can access the instance, VPC Service Controls prevent data exfiltration, and automated encryption at rest with customer-managed encryption keys (CMEK) gives you full control over your data's cryptographic lifecycle.

That is one of the biggest advantages of storing marketing data in AlloyDB. Once Mailchimp lands in your instance, you can JOIN it with any other table — GA4 exports from BigQuery (via federated queries), CRM data, product catalogs, other ad platforms — using standard PostgreSQL syntax. Because AlloyDB is fully PostgreSQL-compatible, the entire ecosystem of PostgreSQL extensions, BI tools, and ORMs works out of the box. Supermetrics supports 170+ data sources that can all land in the same AlloyDB instance, and for advanced use cases you can tap into AlloyDB's built-in Vertex AI integration to run ML predictions directly inside SQL queries on your marketing data.

All standard Mailchimp reporting fields are available, including Emails sent, Open rate, Click rate, Bounce rate, Unsubscribe rate, Unique opens, and many more. You select exactly which metrics and dimensions to transfer during setup, and you can add or remove fields at any time without losing historical data. AlloyDB's columnar engine automatically accelerates analytical queries on large tables — aggregations across millions of rows of Mailchimp data can run up to 100x faster than standard row-based PostgreSQL, giving you warehouse-grade performance without leaving the PostgreSQL ecosystem.

Data freshness depends on your transfer schedule. You can run transfers hourly, daily, or weekly. Most users schedule daily transfers so yesterday's complete data is ready each morning. Supermetrics uses incremental loading — only new and updated records are transferred — so even large accounts refresh quickly. AlloyDB's adaptive autoscaling handles traffic spikes during data loads without manual intervention, and its intelligent caching layer keeps frequently queried marketing dashboards responsive throughout the day.
