Validation Logic

async function validateUsageLimits(org: Organization) {
  const config = getOrgConfig(org);

  // Check daily email limit
  const todayCount = await getEmailsSentToday(org.id);
  if (todayCount >= config.emailsPerDay) {
    throw new Error(`Daily limit reached (${config.emailsPerDay})`);
  }

  // Check monthly email limit
  const monthCount = await getEmailsSentThisMonth(org.id);
  if (monthCount >= config.emailsPerMonth) {
    throw new Error(`Monthly limit reached (${config.emailsPerMonth})`);
  }

  // Check domain limit
  const domainCount = await getDomainCount(org.id);
  if (domainCount >= config.domainsLimit) {
    throw new Error(`Domain limit reached (${config.domainsLimit})`);
  }

  // ... other validations
}
