ReferenceCLI commands
email-sdk doctor
Check whether required adapter configuration is present without authenticating to the provider.
RESEND_API_KEY=re_xxx email-sdk doctor --adapter resendSuccess prints:
resend looks configured.Selection
Use --adapter <name> or the --provider alias. Without either flag, the command selects the first adapter whose required environment variables are all set.
What it checks
doctor checks the required environment variables from the CLI registry. It also recognizes the corresponding credential flags, such as --api-key, --server-token, --host, or provider-specific account fields.
It does not call the provider, verify sender domains, inspect API scopes, or prove deliverability.
Failures
- Unknown adapter:
Unsupported adapter "<name>". - Missing values:
Missing environment for <adapter>: <NAMES> - No explicit or detectable route:
Pass --adapter or set the required environment for one adapter.
Use send --dry-run after doctor to validate a representative message and adapter-specific constraints.
Send command
Validate the exact message without provider delivery.
