## Best Practices

### Domain

#### Use Subdomains

Use the subdomains such as `updates.yourdomain.com` or `notifications.yourdomain.com` for your emails.

Each domain will have its own reputation. So, one subdomain will not affect the other.

#### Warm Up Your Domain

Warm up your domain for better deliverability. You don't need to do anything manually. MailDiver will handle it for you.

#### Add DKIM, SPF, and DMARC Records

Even if DMARC is not required, it's highly recommended that it be added.

### Email Delivery

Monitor your deliverability insights. Try to delete the inactive contacts. Regularly monitor bounce rates and open rates.

### Email Content

Use a better email subject line. Make sure the content is engaging and relevant. Always add an unsubscribe link to your broadcast emails.
