Error message

failed to get all emails: %w

What it means

GetAllEmail wraps any error returned by mail_boxes.AllEmail(ctx, req.Domain) with this message. AllEmail reads every email address for a domain, so the wrapped error is typically a database/query failure, not a client-input problem.

Solutions

1. Read the wrapped inner error to identify the actual DB failure.
2. Verify PostgreSQL connectivity and that migrations have run (mail_boxes tables exist).
3. Retry the request if the failure was transient (pool exhaustion, timeout).

// Light pre-check: DB reachable before listing
if err := db.PingContext(ctx); err != nil {
    return fmt.Errorf("database unreachable, skip GetAllEmail: %w", err)
}

data, err := api.getAllEmail(domain)
if err != nil && strings.Contains(err.Error(), "failed to get all emails") {
    // log the wrapped cause; retry with backoff for transient DB failures
    return retryWithBackoff(3, func() error { _, err = api.getAllEmail(domain); return err })
}

When it happens

Trigger: Calling GetAllEmail when the database is unreachable, the mail_boxes table/schema is missing, or mail_boxes.AllEmail encounters a query error for the given domain.

Common situations: PostgreSQL down or connection pool exhausted; migration not applied; transient DB timeout during heavy load.
