Which of the following is NOT a tool you can connect to a HubSpot campaign?
- Blog
- Workflow
- Campaign strategy
Explanation
HubSpot campaigns are built by associating campaign assets created in other tools, such as blog posts, marketing emails, and workflows. The campaigns documentation explicitly lists blog posts and emails as campaign assets, and it also states that workflows can be associated with multiple campaigns. Campaign strategy is not an asset connection type in the campaigns tool. It is a planning concept, not a HubSpot campaign asset or tool association. HubSpot Knowledge Base+1
