Thorough Internet Research goes into finding Business Email Addresses for you. We want *You* to be confident which email addresses are going to get delivered, which ones *might* get delivered and which ones will never get delivered. So we color them differently.
Here’s a screenshot of different status and colors you will see.
We recommend that you DEFINITELY use 1 & 2.
We recommend you NOT to use 4.
We recommend you use 3 only if you feel that taking the risk is worth the reward for you.
If you like technical details, here’s what you’ll want to know:
1-Deliverable (High) : The email address has been validated with that company’s email server and is a valid email account.
2- Deliverable (Medium) : The email address has been projected based on a statistical analysis of the email patterns of that company / Co-Worker’s email addresses, but the company’s email server refuses to verify or deny if email is correct.
3- Probable : The email address was projected. A handful of co-worker email addresses are available on the Internet, if any. Also, the company’s email server refuses to verify or deny if email is correct.
4-Invalid : The email address has been checked with that company’s email server. They say it’s 'Not a real email address.
