Since Hook Security is in the business of simulating phishing emails, from time to time, our regular, transactional emails communicating our monthly preview or onboarding emails may be blocked.  In order to address this, a partner may elect to whitelist our transactional IP addresses in addition to our testing and training IP addresses. (What IP addresses should I whitelist?) Additional IP addresses are below along with a few domains that we recommend you add to your mail client's 'safe sender' list. (We know it is a lot, so focus on the **BOLD** IP Addresses if you would like to try those first.) ``` 63.174.23.0/24206.210.87.0/29206.210.87.8/29206.210.87.16/29206.210.87.24/29206.210.91.24/29206.210.91.80/2954.174.60.0/23143.244.80.0/2018.208.124.128/2554.174.53.128/30158.247.16.0/2054.174.59.0/2454.174.63.0/243.93.157.0/2454.174.52.0/24139.180.17.0/2454.174.57.0/24hooksecurity[dot]cohooksecurity[dot]email ``` - [Getting Started](https://support.hooksecurity.co/getting-started?hsLang=en#main-content) - [General](https://support.hooksecurity.co/getting-started?hsLang=en#general) - [General Safelisting](https://support.hooksecurity.co/getting-started?hsLang=en#general-safelisting) - [Microsoft Safelisting](https://support.hooksecurity.co/getting-started?hsLang=en#microsoft-safelisting) - [GSuite Safelisting](https://support.hooksecurity.co/getting-started?hsLang=en#gsuite-safelisting) - [Firewall/Spam Filter Safelisting](https://support.hooksecurity.co/getting-started?hsLang=en#firewall-spam-filter-safelisting) - [Creating Groups/Adding Targets](https://support.hooksecurity.co/getting-started?hsLang=en#creating-groups-adding-targets) - [Reporting Plug-In](https://support.hooksecurity.co/getting-started?hsLang=en#reporting-plug-in) - [3rd Party Integrations](https://support.hooksecurity.co/getting-started?hsLang=en#3rd-party-integrations) - [Platform Settings](https://support.hooksecurity.co/getting-started?hsLang=en#platform-settings) - [Hook Academy](https://support.hooksecurity.co/hook-academy?hsLang=en#main-content) - [Campaign Ideas](https://support.hooksecurity.co/hook-academy?hsLang=en#campaign-ideas) - [Industry Specific Campaigns](https://support.hooksecurity.co/hook-academy?hsLang=en#industry-specific-campaigns) - [Course Reviews](https://support.hooksecurity.co/hook-academy?hsLang=en#course-reviews) - [Mastering Reporting](https://support.hooksecurity.co/hook-academy?hsLang=en#mastering-reporting) - [Becoming Compliant](https://support.hooksecurity.co/hook-academy?hsLang=en#becoming-compliant) - [Suggest a Hook Academy Topic](https://support.hooksecurity.co/hook-academy?hsLang=en#suggest-a-hook-academy-topic) - [Tests/Campaigns](https://support.hooksecurity.co/tests-campaigns?hsLang=en#main-content) - [Reseller Only](https://support.hooksecurity.co/tests-campaigns?hsLang=en#reseller-only) - [School](https://support.hooksecurity.co/school?hsLang=en#main-content) - [3rd Party Integrations](https://support.hooksecurity.co/school?hsLang=en#3rd-party-integrations) - [Troubleshooting](https://support.hooksecurity.co/school?hsLang=en#troubleshooting) - [Branding](https://support.hooksecurity.co/school?hsLang=en#branding) - [Course](https://support.hooksecurity.co/school?hsLang=en#course) - [Students](https://support.hooksecurity.co/school?hsLang=en#students) - [Automations](https://support.hooksecurity.co/school?hsLang=en#automations) - [Reports](https://support.hooksecurity.co/reports?hsLang=en#main-content) - [Generate Reports](https://support.hooksecurity.co/reports?hsLang=en#generate-reports) - [FAQs](https://support.hooksecurity.co/faqs?hsLang=en#main-content) - [Troubleshooting](https://support.hooksecurity.co/faqs?hsLang=en#troubleshooting) - [Campaign of the Month](https://support.hooksecurity.co/faqs?hsLang=en#campaign-of-the-month) - [Reseller Guide](https://support.hooksecurity.co/reseller-guide?hsLang=en) - [Hook Security Updates](https://support.hooksecurity.co/hook-security-updates?hsLang=en) - [Onboarding Guides](https://support.hooksecurity.co/onboarding-guides?hsLang=en) - [Managed Services](https://support.hooksecurity.co/managed-services?hsLang=en) - [Default HubSpot Blog](https://hooksecurity-6535385.hs-sites.com/blog) [![Newsletter\_Logo-08](https://support.hooksecurity.co/hs-fs/hubfs/Newsletter_Logo-08.png?width=250&height=59&name=Newsletter_Logo-08.png "Newsletter_Logo-08")](http://hooksecurity.co) Proudly Headquartered in Lakeland, Floirda Copyright © 2026, Hook Security Inc.
