Did you know that over 45% of all email traffic is spam? That means for every legit email you get, another unwanted one lurks in the background, too – all due to a lack of reverse DNS (rDNS).
So, how do you get into your customer’s good graces when you can’t even get past the spam filter?
The answer is V6Proxies’ mailing proxies—clean IPs designed especially for email services. However, these clean IPs are just one part of the puzzle. The key to nailing your mailing services is Reverse DNS for maximum deliverability.
Here’s what you need to know about it.

What is Reverse DNS?
Reverse DNS is a clever method for resolving an IP address back to the domain name it’s associated with. Simply put, it’s the opposite of the standard Domain Name System (DNS).
How Reverse DNS Works
Reverse DNS traces an email IP back to its associated domain name using Pointer (PTR) records. Here’s how the process works.
- The mail server starts a reverse DNS lookup by searching the PTR associated with a specific IP.
- The DNS server searches the database for the corresponding PTR record.
- If a PTR record is found, the DNS server returns the associated domain name to the mail server.
Reverse DNS vs. Forward DNS
With regular DNS, you need to enter a name to find out their IP address. With reverse DNS, you can use their IP address to find the name of the computer or server it belongs to. This way, email servers can identify whether the sender is trustworthy.
The Role of Reverse DNS in Mailing Services
Reverse DNS plays a massive role in mailing services – here’s how it contributes.
Email Deliverability
When you send an email, the recipient server checks the sender’s IP to see if it matches the domain name in the email. A correct rDNS record verifies your identity, so it won’t flagged as spam and blocked. Studies indicate that emails without a proper PTR record are most likely to get rejected or filtered.
Spam Filtering
Spam filters are less likely to trash emails with accurate rDNS since they don’t look suspicious. As long as your domain name matches your IP address, you’re good to go.
Reputation Management
A large percentage of email recipients look up the sender’s domain reputation before they open an email. If your rDNS record is valid, the receiver will associate your organization with trust and credibility.
Recipient Trust
Around 1 million IPs are looked up on rDNS servers every day because receivers want to know who’s emailing them. To gain their trust, ensure your IP is associated with consistent rDNS accuracy.
Advantages of Reverse DNS
Investing in reverse DNS can completely transform your mailing services. Here are some of the many benefits you can expect.
Clean IPs
Your IP is basically your advocate. If it’s associated with spam, your emails won’t reach the right inboxes. Clean IPs, on the other hand, have a pristine reputation, so you won’t have any trouble bypassing spam filters.
