Whitelist TouchBasePro sending addresses

Support Portal  »  Knowledgebase  »  Viewing Article


If you're having trouble either receiving your own emails or accessing our software, you may want to ask your IT team to whitelist our addresses.


Sending IP addresses

Below are the IP ranges we use for sending email: 


Authenticated domains

If you have set up DKIM authentication, you'll also want to allow the domain you have authenticated.



Some anti-spam services on your local network may be particularly strict, requiring our domain to be added to your own existing SPF record. In this case, you can add the following to your record:


If you don't have an SPF record, please add a TXT to your domain's DNS with the following:

v=spf1 ~all


Recommended settings

If you need to whitelist IPs to receive email from our servers, we recommend mail administrators set up custom rules within their email filtering software. To work, the rule must match both of these conditions:

  1. The email is coming from one of our IPs.
  2. The email contains your domain in the "From" address.

Any email that doesn't match one of these conditions can be rejected. A custom rule like this is generally an acceptable solution for security teams and mail administrators.
