Whitelisting IP addresses in the Platform

Modified on: Wed, 16 Nov, 2022 at 7:54 PM

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

If you're also finding that a large number of people on the same private domain are reporting your messages to go to spam, we recommend also asking your subscribers to partner with their IT department to whitelist Cision at the server level. 

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.   

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 organisation should append the below SPF record to your existing record: 
“v=spf1 include:email.prnewswire.com”
