Quickbase Email IP Address Range Migration
[Article most recently updated March 2025]
Quickbase keeps an up-to-date Sender Policy Framework (SPF) record for all email servers used to send email from our platform. Please note that if you use SPF, you can still adhere to your organization's spam filtering policy without having to allowlist the IP addresses of approved senders. See http://en.wikipedia.org/wiki/Sender_Policy_Framework for more information on SPF. Important: Note that SPF is our recommended and supported method for spam filtering.
Since the IP address ranges of our email servers will change without notice, customers should NOT allowlist IP addresses as a first step to ensure Quickbase emails are received. If your organization does allowlist email IP addresses, you should plan to implement SPF as soon as possible. Please see further details on IP allowlisting and Quickbase Email Deliverability Solutions for Spam Filtering in the article linked HERE.
If you DO choose to allowlist IP addresses, despite our strong encouragement to do otherwise, here is the CURRENT range used by the Quickbase Platform.
