"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 customers' email will have no effect on your delivery. Buying one also provides access to many other features.
To purchase Private IPs:
Go to the Settings screen
Click Purchase Private IP
You can purchase up to 2 private IPs at a time
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.
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.
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.
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.
