Email leads aggregator - is this useful?

Hey!

I'm looking to build a SAAS as a side project. I'm tinkering with some ideas, but the one I'm most excited about is this email lead tracker.

I've build this as a custom feature for the company I currently work at.

The idea is that the marketing team has email leads coming from multiple sources: Hubspot, Mailchimp, etc. This app would aggregate all the emails gathered in a set time period and display them in a list, listing the source (software and email list), signup date and time, etc.

For the marketeers in IndieHackers: is this something you would be interested in? Does it sound useful?

Our internal marketing team loves it! But I wonder if other teams have the same problem. Before this feature they had to do all this manually across multiple softwares and that took around 1 hour. Now takes a couple of seconds.

Thanks for reading!
