How can I block HS from creating contacts using our company domains we have 4-5? Now I manually delete those contacts, there are not so many but maybe there is another way? This started happening a few weeks back. I am using premament delete.
Hi @KubaNowakowski,
That depends on how these contacts are currently being created. Have you checked what the original source of these contacts is? Understand Original and Latest traffic source properties
The answer will influence how this can be solved.
Best regards
Thanks for responding @karstenkoehler
Today I have already got three contacts, Their originals source are both: Offline, CONVERSATIONS, addMessageUser
Hi @KubaNowakowski,
Then these contacts are being created from your conversations inbox: A guide to the conversations inbox
Unfortunately, this can currently not be changed or disabled. Other users have requested this before however: https://community.hubspot.com/t5/HubSpot-Ideas/Disable-automatic-contact-creation-for-Conversations/idi-p/203881
As usual, I’d recommend upvoting and commenting. The product team reviews these requests based on their popularity.
You can also make it easier for others to find the request (and drive traction) by accepting my reply as a solution. I’d appreciate that, too.
Have a great day!
Much apreciated! Now I know 
What about contacts that are created from other sources like Extension or by adding someone to CC in an email? I used the permament delete but unfortunatelly those contacts are just added again the next day. Is that not working as decsribed? Please help!
