Started with high expectations but left disappointed **Rating:** 1.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** December 19, 2025 **What do you like best about Telescope?** It's easy to use and the idea behind it is good **What do you dislike about Telescope?** Mailboxes don't seem to work properly: barely received out of offices on high volumes of emails that were sent If I download a list, and re-upload, it only recognizes 20% of the contacts. I don't see how that is possible. The amount of leads it generates has decreased drastically over the last months. Customer support takes very long to respond - seems like they are not active anymore. Can't access the actual database of contacts, only through prompting.
