If you are trying to import more than 1,000 contacts/companies it can break the process
Import by CSV file is very simple, at Salestools we are working with unique prospects/leads that simply means if a person already exists in your database with Salestools , then this prospect/lead will not be imported. So when you import a file it is not an error the prospect is not showing, that prospect will be in your DB but you need to search the person.
!!! Do not import more than 1,000 prospects !!!
