Frequently Asked Questions
A PTR record is the reverse of an A record — it maps an IP address back to a hostname, instead of a hostname to an IP. Many receiving mail servers check that a sending IP has a PTR record, and that it roughly matches the sending domain, before accepting mail. An IP with no PTR record, or one that still shows a generic hosting-provider hostname, is a common reason legitimate mail lands in spam. See rDNS VPS for the full picture.
Yes. Custom rDNS/PTR records are available on every plan by request through a support ticket — no extra fee, no approval wait beyond normal support response time. See rDNS VPS and what is rDNS.
No PTR record is configured for that IP address at all. For an IP sending email, this is worth fixing — it's one of the more common, easily-fixed reasons for poor deliverability. See our SPF, DKIM & DMARC checker to check the rest of your setup at the same time.
