BullPhish ID, Kaseya 365 User

BullPhish ID now includes 18 total global sending domains you can use for phishing and training campaigns. This gives you more options when building campaigns while keeping senders consistent across runs.  

To avoid delivery issues, you’ll want to safelist these new domains in your email security and filtering tools before using them. The release includes domains like micros0ft-services.net, ms365alerts.net and zoom-meetingnotice.email.  

With the domains allowed ahead of time, your simulations are less likely to get routed to spam or blocked at the gateway — so you get cleaner results and fewer “I never received it” tickets from users. Safelisting guides are available for common platforms.
