How to choose between a public changelog and a private customer email

Choose a public changelog when the change helps many users understand the product, and choose a private customer email when the impact depends on a specific account.

Small SaaS teams often blur these channels. A public changelog becomes a place for account-specific apologies, while private emails repeat broad product updates that should have been searchable. The result is fragmented communication. Future customers cannot find the change, and affected customers still do not know whether it applies to them.

A public changelog works well for feature releases, documented behavior changes, new integrations, pricing page updates, security improvements that can be discussed safely, and deprecations with broad timelines. The writing should explain what changed, why it matters, and where to find the setting or docs. It should avoid private customer details and internal incident history.

A private email is better for contract-specific pricing, account migrations, data corrections, usage spikes, billing exceptions, beta access, and incidents that affect only a defined group. The email can include account dates, usage thresholds, next steps, and a support contact path. Those details should not be buried inside a public changelog.

The decision test is simple: would a future user searching the product name benefit from seeing this update? If yes, publish a changelog entry. Does the customer need account-specific action or context? If yes, send a private email too. Many important changes need both, but each channel should carry the right level of detail.

A clean communication rule reduces support load. The changelog becomes the permanent public record, and the email becomes the account-specific action request. Mixing them makes both weaker.
