All reviews here are just wrong. They just wrote these reviews to get 5 free credits. Even though I left a good review, they avoid giving free credits. Don't use this service.
There are lots of other free services much better than this one.
The terrible thing is that if you use this extension, your LinkedIn profile will be blocked.
Don't use this shit service.
Extremely efficient app. User friendly with the getemail extension for Linkedin. It helped me to reduce my time consuption on searching for personal and professional emails in approx 10x. Clearly recommend it!
