I need to have all new contacts that are added to List A automatically also be added to List B and List C. All three lists already exist.
Any tips on how to take this happen? Thank you.

Hi there,
To automatically add contacts from List A to List B and List C, you can use HubSpot workflows:
Go to Automation > Workflows > Create workflow > Start from scratch.
Choose Contact-based workflow.
Set trigger: List Membership > Select List A.
Add Actions: Click + to add actions:
Add to List > Select List B.
Add to List > Select List C.
Review and activate it.
Now, new contacts in List A will also be added to Lists B and C automatically!
Hope this helps!
Best,
RHJ
Hi RHJ,
Thank you! It almost worked. But I only have the option to add to a static list (under the “marketing” category in “add actions.” And the List B and List C are active lists.
Do you have any suggestions? Thanks.
Hi @CFU,
If lists B and C are active lists, this can be simply achieved by adding a filter for list membership:
If your list B and C already have criteria, simply add this additional filter using the OR Add filter group at the very bottom.

Best regards!
Hi Karsten, thank you for those steps! I followed them to a T. Since I’m a HubSpot newbie, I’m not sure what the steps I did is doing in real world application. ![]()
Does that mean List B and List C now will automatically have all of the same contacts that are added to List A? And this also means I don’t need to create a workflow or do anything else?

Correct, if you followed my steps, contacts that enter list A will automatically also enter list B (and C). No need for a workflow ![]()
You can test this easily by checking any contact on list A – they will also appear on list B and C. (Sometimes this will take a few seconds and in rare cases minutes.)
If my answers helped you, please consider marking them as solutions. I’d appreciate it a lot.
Have a great day!
Hi Karsten,
I ran the test and it works. I really appreciate your help! Thank you so much! ![]()
