Sending IP Addresses

Many organizations have firewalls and other mail security tools in place to help protect from attacks on the internet. Knowing the IP addresses of the incoming emails allows your team to specifically trust emails coming from Staffbase Email or to create rules in the system to deliver Staffbase Email safely.

While Staffbase Email uses AWS SES to deliver emails, the outgoing IP addresses are dedicated and specific to Staffbase Email. The rules created for these IP addresses will apply only to mails from Staffbase Email and not any other individuals or businesses who may also be using AWS SES.

Staffbase Email maintains a set of IP addresses from which your emails can be sent. These IP addresses are dedicated and specific to both our US and EU Staffbase Email instances. Below you can find additional information on our sending IP addresses specific to both our Staffbase Email instances.

Emails sent from the Staffbase Email web app will be sent through one of the IP addresses listed below. There is no guarantee which IP address an individual email will be sent through. In order to allowlist the email, the entire range need to be allowlisted. Also, the IP addresses are subject to change from time to time. Check this article to ensure you have the most up to date information.

Customers sending emails from the web app can check the Staffbase Email sending IP SPF record to find the outgoing IP addresses of the emails. The IP addresses can be obtained by querying Staffbase Email's SPF record.
