- We only use the Broadcast email build-and-deliver tool, so tool specific comments are only in reference to that.

- This is a small, high-touch organization. You WILL be important to them. They WILL be responsive to your suggestions and requests. Not all of them will be put into practice - customers have different needs, and recommendations have to be globally applicable - but they listen and give them fair consideration. That's rare, and really welcome.

- Being SaaS, they are updating all the time. With fixes, improvements, added functionality.

- Various users have contacted support now and again (via online chat) and have reported being very happy with the responsiveness. And the person responding *never* gives in to the temptation to tell them that they could have found their answer in the online help documents. That must take an immense amount of self-control.

- All software tools make trade offs between simplicity and flexibility. The more flexible, the more complex (Look at Paint vs Photoshop, or Windows Movie Maker vs Premiere Pro). Cerkl has found a good balance. We have more than 100 users of the tool, with the expected range of technical ability, comfort with new tools, design sense, and so on. Many were intimidated at the prospect of moving from the tool they knew - as unreliable and lacking as it was - to something new. Unprompted, several have subsequently contacted me to say that indeed, as promised, this was better. And it was really no contest. The learning curve is not steep.

- The Metrics (aka "Insights"). We never had them before. I'm like a kid in a candy store. Review collected by and hosted on G2.com.

- The balance between flexibility and complexity is, as noted above, quite good...but never perfect. One example: a lack of ability to word wrap around an inserted image. It's a design decision, made for valid reasons having to do with that balance, but it can be frustrating for people looking to design more complex newsletters, for example.

- The Metrics (aka "Insights"). We know the drill - because someone opened an email does not mean they read it, or understood it, or took action as a result. That's not an issue with the tool of course, but metrics require context. Some of the metrics provided are not useful, and potentially misleading (things like preview panes, and "return to last email opened" settings can badly mess with the (non-unique) open rates). I'd recommend that be removed until it's validated or corrected. Review collected by and hosted on G2.com.
