All the emails which GetProspect finds are verified through an in-built email verification engine.
After an email address is verified, GetProspect will assign it one of the following statuses:
Valid email address. It means that our system has received a confirmation from a mail server that this email address exists. The accuracy for valid emails is 95%.
Accept all email address. This email address can receive messages, but due to a domain-wide setting, it is not possible to determine a true validity of such email, so we mark them as Accept all. Such emails are also known as "catch-all" or "unverifiable" emails. Learn more on accept all email addresses.
When you re-verify the email address, or verify the email address found via other sources, there can be one more status:
Invalid email address - means an email address does not exist or is not active anymore.
