PTR (also known as rDNS) is a crucial DNS record that links your IP address to your domain name. Here’s why it matters for email marketing:
- It builds trust with recipient mail servers and helps prevent your emails from going to spam.
- It’s often required by ISPs for proper email delivery.
To set it up:
- Access your VPS control panel or contact your provider’s support.
- Request to set a PTR record pointing your IP to your sending domain (e.g., mail.yourdomain.com).
- Verify it using online tools like MXToolbox.
Proper rDNS setup improves your sender reputation and deliverability.
