[5.x]: Allow BCC'd Recipient, Email Subject, and Reply-To in Commerce Email Settings to Use Environment Variables

[romainpoirier]

What happened?

Description

In the Commerce Settings > Emails section, only the Status Email Address and From Name can currently be set as environment variables.

On my staging environment, I need the BCC’d Recipient to differ from production. However, since the /admin/commerce/settings/emails/primary/1 section is not accessible when CRAFT_ALLOW_ADMIN_CHANGES=false (which is the expected setting for staging), I cannot modify this value.

Why does Craft Commerce not allow additional email options, such as BCC’d Recipient, Email Subject, and Reply-To, to be defined as environment variables? Is this an oversight?

Is there an alternative solution, such as defining these settings via config/commerce.php? If yes, what are the exact keys to use? The BCC’d Recipient option, for instance, is not documented here: Commerce 5.x Configuration

In my case, being able to set BCC’d Recipient as an environment variable is crucial. However, having the ability to set Email Subject and Reply-To in the same way would be highly beneficial.

Steps to reproduce

1. Set up a staging environment with CRAFT_ALLOW_ADMIN_CHANGES=false.
2. Attempt to configure the BCC’d Recipient for Commerce Emails to differ from production.
3. Notice that this value cannot be set via environment variables or the config/commerce.php file.

Expected behavior

The BCC’d Recipient, Email Subject, and Reply-To fields should support the use of environment variables for easier configuration across environments (staging, production, etc.).

Actual behavior

These fields cannot be defined as environment variables, and there is no documented alternative to set them via the configuration file. This limits flexibility, especially in non-production environments where admin changes are restricted.
