Your best way to check email list

Hi, using this email checker since 2weeks i would try ask if anyone use this product and what do you think about this ?
If you have other tool or tips for test big list of email hope you can share :slight_smile:

Good morning,
I just tested your tool and I find it efficient in addition to being cheap… I used Hunter before but Ninja Mail allowed me to test more email addresses in a given time.
