Domain names and IP ranges that can be allowed for Staffbase Email functionality
Depending on your organization's network security requirements, allowlisting select Staffbase Email (formerly Bananatag) domains is required to ensure the successful delivery, tracking of emails, and avoiding spam folder.
Allow these domain names for basic email functionality:
- *.bl-1.com
- Tracking Event System
- *.bananatag.com
- App + Image Hosting
- bt-prod-eu-c1-email-designer.s3.eu-central-1.amazonaws.com
- EU Hosting only
Many organizations have firewalls and other mail security tools in place to help protect from attacks on the internet. Knowing the IP addresses that emails will be coming from allows your team to specifically trust emails coming from Staffbase Email, or to create rules in systems for how those messages should be handled that are specific only to messages coming from Staffbase Email.
While Staffbase Email uses AWS SES to deliver emails, the outgoing IP addresses are dedicated and specific to Staffbase Email, so rules created for these IP addresses will apply only to mail 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 that your emails can be sent from. 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.
More details on how to access our different instances.
Customers sending from the web app can check the Staffbase Email sending IP SPF record to find the outgoing IP addresses emails will be coming from. The IP addresses can be obtained by querying Staffbase Email's SPF record (at the spf.bananatag.com subdomain).
This is how to query the list of IP addresses from Terminal on Mac
(including a filter to include only the SPF record):
dig TXT spf.bananatag.com +short| grep 'v=spf1'
Here’s the equivalent query using the Windows command prompt
:
nslookup -type=TXT spf.bananatag.com | find "v=spf1"
