Whitelist IP Addresses

Since our IP addresses do sometimes change, the best way to ensure good email deliverability would be to either whitelist emails coming from sgizmo.com in your firewall or even better yet, set up an SPF record that allows sgizmo.com to send messages in your name (ie, from @youremail).

However, if you absolutely must use the IP addresses for ensuring deliverability of either Send Email actions or Email Invitations from SurveyGizmo, they are provided below. Be advised that in the future, as SurveyGizmo scales to serve more customer’s needs, more servers and unique IP addresses will be added, and we do not publish our IP addresses to non-customers and thus do not announce this publicly on our site.

Here are the IP addresses:
