"Private IPs" are dedicated IP addresses that are assigned to your account. Your email and only your email is delivered from these private IP addresses.
Using private IP addresses gives you complete control of your IP's external reputation. Other Elastic Email customer’s email will have no effect on your delivery. Buying one also provides access to many other features.
Setup To purchase Private IPs follow this tutorial:
Exclusive Delivery Only your email gets sent using the private IP. Your email, domain, and IP, are able to build a reputation together without other email affecting it.
SMTP Bounce Errors You will gain access to the exact SMTP errors returned by recipient servers in your email logs. While we all hope delivery issues are rare, they do happen. When they do, having the exact SMTP error can help with troubleshooting.
Custom (white label) rDNS You can "white label" your private IP with your domain (setup rDNS) by adding an A record to your default sender domain's DNS settings that points to your private IP. Common A records are "mail1.yourdomain.com" or "mta.yourdomain.com". You can only have one A record for the private IP, this means that only one domain may have the record added. If the record is added, please contact Elastic Email Support and provide the A record. We can then complete the rDNS setup.
Please note that custom rDNS is available to Unlimited PRO and Email API PRO plans only (With addition to all grandfathered plans).
IP Reports A whole new reporting screen is unlocked with a Private IP. Gain access to a break down of delivery stats by domain for each private IP you have. Use the quick links to check sender reputation metrics with some popular reputation providers.
Whitelisting Whitelisting simply means that your private IP has been pre-approved by the recipient server to send them an email. It can help reduce the chances of bounces for those recipients. You can "whitelist" your IP with some ISPs ensuring the best delivery possible to that ISP. Here is a list of the major ISPs and the whitelisting options they provide: Whitelist Providers. There are some whitelist processes that will require help from our support staff.
Private IP Pools Want more than one private IP? There is no limit to the number of Private IPs an account can have. You can even create and manage your own IP pools and customize which IPs you want to use for specific campaigns and even assign IPs to specific Sub Accounts. This tutorial shows you how:
Is A Private IP Right For You?
Using a private IP address does unlock a lot of features, but it also comes with a bit more responsibility. While you are benefiting from not sharing IPs with other customers, you are also losing the same benefit. Sometimes other senders can help keep IP addresses "warmed up", or balance out delivery ratios if your campaign did not do so well. It is also important to consider frequency and mail type. If you only send once or twice per month or have very low volumes, then using private IPs might not be the right approach.
While there are many factors involved, this table will help you decide if private IPs might work for you.
