Ok so, every day we're keeping track of many metrics while working on Mailbrew, and we're trying to define what will by our KPIs. A great friend of ours, Ferruccio, suggested that we define 3 key metrics: leading metric like email sent every day, a lagging metric like revenue, and finally a health metric.
Regarding this last metric, we've picked Open Rate. We believe that it's a great measure of how healthy Mailbrew is in general, and it should guide us while developing the private beta.
Well, we're pretty stoked to have 95% open rate with our 120+ active beta users. It's exciting because it means that while we find the right positioning and target market, we know that the rights users fall in love with Mailbrew and read almost every single email they receive.
I think the reason it work it's because once you invest a little time in crafting your own newsletters, from your own sources, you don't want to miss a single issue, while with other newsletters you don't feel as bad about it.
If you have any feedback on what metrics we should keep our eyes on, I'd love to hear it. And happy to answer any questions about our private beta so far.
