I second this. Any update¿
Guuuysss!!!
Could it be this simple? I just tested this and it seemed to work.
In your inbox, you can select your log and track settings. If you get rid of logging new contacts, it won’t create it in your CRM.
Basically, you only want to log emails for exisiting contacts… these are either inbound leads or leads you have uploaded yourself as qualified to be in the system.
It seems to be working for me… hope it helps you!
@KKaiser85 are you referring to your email or a shared email inbox? We are having issues with inbound emails to our info@ and support@ emails, not james@company.com type addresses
For is it was always a single email. If it’s happening to your shared email, it must have the sales extension turned on? If so… I would imagine the same settings apply.
I came here to see if there was a solution and I can’t believe after 3 years there still isn’t a solution. It seems as if there should be a “Click box” on the hubspot to exclude domains or emails from being logged as a contact. Even deleting contacts won’t solve the problem because as soon as they reply a new contact is created.
Solution:
In the Hubspot extensions add a click box to never create contacts based on domain or specific emails. In Outlook or Chrome add in the same feature.
Since the need was raised,
there still hasn’t been a solution after five years. 
Today 20230502
To add to the use cases stated before for providing more control on auto-contact creation, we sync our product sign-up contacts to HubSpot. Then a marketing email is sent to the sign up to schedule a meeting via a meeting link. The contact fills in a different email to the sign up email address. Then HubSpot creates a duplicate record, one which does not have our product contact id, resulting in a broken integration between our product and HubSpot.
any news?)
yes, indeed very annoying that we have to pay for SPAM contacts etc.! please fix this!
How many more upvotes do you need before you make a change? What’s the point in having a system like this if you’re not going to listen to your customers?
When you’re redirected to the community, it usually means that there’s no solution available, and you should quickly explore alternative methods. I believe HS has the capability to address this matter, but currently, fulfilling your specific request is not a priority for HS. However, with ChatGPT, HS can immediately react and respond by creating a chatspot!
@cdewey22 any updates on this ticket? I see it has been two years since the idea was submitted but I could not find the function.
I second this. Any update?
Any update on this idea? Hope to get a setting tab to turn this feature on and off.
Any update on this feature? Looks like it’s been over 2 years now.
Absolutely this needs to be looked at. I get so many spam emails from suppliers that it’s causing un necessary clutter in my data records.
As they say, you put rubbish in; you get rubbish out - so this is bound to have an impact on the quality of data and it’s time-consuming to keep deleting spam contacts. HubSpot is meant to make your life easier isn’t it? Please make a fix for this soon 
Are there any updates for this? I can see this issue is here since 2018 and is not solved yet?
This is still an issue in 2023. Has this been resolved or forgotten about?
We want that feature.
Adding my voice - should be an easy fix.
When we reply to an email cc’ing the whole world, they are all added to HubSpot - Yuck!
