SalesQL appears to be a legitimate service based on user reviews and ratings. It is a lead generation tool that integrates with LinkedIn to help users find contact information such as email addresses and phone numbers. Users have praised its ease of use, accuracy, and affordability. However, some users have reported issues with LinkedIn account bans due to the use of SalesQL's Chrome extension, and there have been complaints about poor customer support and refund policies. Overall, SalesQL has received positive feedback for its functionality and value for money, but potential users should be aware of the risks associated with LinkedIn's policies.
