Can I Whitelist an IP Address?

Information on IP whitelisting

Written by Cision

If you often send emails from the Cision Communications Cloud internally – to yourself or colleagues – and want to ensure deliverability, it is advised that your organization utilize one or both of the strategies below. If you have an internal IT team, they can help you complete this on your end.

Whitelisting Cision gives the green light to messages sent from Cision and instructs the incoming mail server to route them to the inbox. Whitelisting does not guarantee inbox delivery (that is something no email provider can guarantee), but it goes a long way toward preventing the recipient's incoming mail server from sending your email, Newsletter, or Digest to spam.

SPF

In order for Cision to successfully spoof the from address of emails with a customer’s domain and increase the chance of inbox deliverability, your organization should append the below SPF record to your existing record:

“v=spf1 include:email.prnewswire.com”

Whitelisting IP Addresses

If you are accessing your media lists by navigating to the Influencers tab and you choose to whitelist emails sent from the Cision Communications Cloud, you can whitelist the IP addresses below. At current, that list is:

  • 198.37.147.116

  • 198.37.147.117

  • 198.37.147.137

  • 198.37.147.154

The Cision Communications Cloud also has a backup email delivery system with a separate range of IP addresses. You may choose to whitelist these IPs, as well. The IP range for this system is 65.123.29.0/24.

If you are still having issues receiving emails from the Cision Communications Cloud, you may want to update your personal email settings:
