Filtering out Companies that have not been contacted via Sequences
Currently there is no way to filter by companies that are not in a sequence but this can be done for Contacts. This is done by using the filter: Contact Property - Now in sequence = NO. This will then match all Contacts that are not in a list.
However, when working with the above example for Contacts, whilst the list reveals all unassociated Contacts with a Sequence, there is still the possibility that another Contact from the Company is enrolled hence, the report would be inaccurate for actioning.
This is quite an important feature to have as it will help understand which Companies HubSpot users are in contact with and where there focus should lie going forward.
