The most useful feature of Kelsa is its ability to integrate with other applications such as Salesforce, Hubspot, Google Apps etc. This makes it easy for marketers to track all their marketing activities and campaigns from one place. When you are using Kelsa, you can easily customize your dashboard according to your needs. I would say the UI could be improved but this is only my personal opinion. I have been working with Kelsa since last 3 years and haven't faced any issues so far. We use Kelsa to manage our customer's marketing campaigns and we also use it to send automated emails to our customers.
