## Inbox Tracker Reviews
  ### 1. Helpful, but very limited

**Rating:** 2.5/5.0 stars

**Reviewed by:** Samantha U. | Account Development Representative, Mid-Market (51-1000 emp.)

**Reviewed Date:** March 14, 2019

**What do you like best about Inbox Tracker?**

eData is a great resource for finding a few key pieces of important information necessary for my line of work. The ability to identify ESP(s), top sending domains, Parent Companies, send volume and even inbox placement are extremely necessary for my line of work. The dataset on eData is extremely valuable and the best this specific website has to offer.

**What do you dislike about Inbox Tracker?**

Unfortunately, the data is very limited and at times feels even outdated. Send volumes don't always make sense and selecting data will sometimes take you to the wrong spot. It wasn't easy to navigate so it took our team a while to pick up on how to use it. Not enough clarification on which sources you should click on and where they will take you. Two stacked search bars makes it hard to distinguish the function of each. 

**Recommendations to others considering Inbox Tracker:**

Possibly locate an additional resource that mirrors this product and the data provided, but perhaps more expansive. 

**What problems is Inbox Tracker solving and how is that benefiting you?**

I work in sales enablement for a major ESP so having raw ESP data on companies is exactly what we need to offer our solution to potential clients. eData is beneficial for projecting necessary key points of data, sometimes all necessary info is located all on one page. We have such a large database of customers, that sometimes this even distinguishes if they're already a current user of our platform. 

**Official Response from Steph T:**

> Thank you for your feedback. We always appreciate hearing how our platform is helpful and ways we can improve it!
