Would to see a way to make email design more user friendly so we can take the design of our emails to the next level.
Sort of linked to my first point, HubSpot is expensive. Great fun, easy to use, does great things but still expensive. I'd like a cheaper version with all the main functionality but restricted in some way. As a very small business it's frightening to see my HubSpot bills.
Support - The support team is always really nice, but they don't always have answers and it sometimes takes a while to get anything fixed.
I think the CMS tools could be easier to use.
Both the blog and landing page tools are not worth the effort. In an entire year of paying for and using HubSpot, we were never able to get either tool working to the standards that we needed.
Overall reliability - at the end of the day, the information our leads filled out in a HubSpot form successfully dumped into SFDC, generally without an issue. That being said, we had multiple problems with duplication; data syncs are painfully slow;
Support & documentation - I can't count the number of times we had to ask for help doing something, and we would receive back a loosely-related article link from the support team that really didn't answer our question.
Links between stylesheets and associated templates could be made more clear. More robust CSS button options. More JS integration
The list and "workflow" concept is pretty clunky. Compared to other providers, who have a logic-based campaign/segmentation structure, HubSpot's methodology is pretty low-tech. It's impossible to handle things like behavior-based segmentation with any measure of agility and competence when the tool you have isn't able to understand user behavior, account for strategy changes, or even report accurately on its own performance.
The analytics in HubSpot are average at best. In particular, we have been having issues with HubSpot not reading UTM tagged links and they seem to not have an answer as to why that is happening.
Like any product, HubSpot took a bit of a learning curve. I found that doing things like the forms it was difficult to tell which page I needed to be on and how I could see the results. Sometimes I felt as though there was "too much" and it often made a simple task complicated.
Customer service is not always prompt when there is a question or concern.
I do not see HubSpot scaling for large enterprises. I believe they are an appropriate solution for SMBs who are committed to content marketing versus lead gen and scoring
Reporting is extremely limited - I expected a lot more since this is a marketing automation software and metrics are key. You can really only choose from preset fields and situations, you can't mix and match any fields you want
It would be nice if all links were trackable automatically instead of having to set up trackable URL's and then set up lists based on those URL's.
As I'm pretty new to Hubspot, I think the site is quite difficult to navigate around. The training academy could be more organized from a beginners point of view. I went to the Inbound Conference and also found there wasn't enough design based tutorials for a beginner to understand.
