Top-level Status Codes

Last updated by Roshan Jonah on August 21, 2017 13:05

Valid - The email address has been deemed to be valid or deliverable.

Safe to Email 

Invalid - The email address has been deemed to be invalid. See Second-Level code for more details 

Not Safe to Email

Risky - Accept All or Catchall Email Address - Email address seems to meet all the right criteria and the domain seems to be accepting email without issues but we cannot say with 100% confidence that it’s valid. 

Accept-all domains have a type of configuration setup that accepts all emails and then tries to deliver to the appropriate recipient. Nearly 90% of the time, these are valid email addresses but we can say with certainty so we recommend exercising caution.

  • If your ESP’s bounce threshold limit of less than 7% - Not Safe to Email
  • If you are on dedicated IP or IP pool – Email Slowly

Unknown - This occurs when the email address meets all the criteria but the related domain is not responding or is down. It's usually deemed as temporary status as we have trouble determining that email address validity. 

Such statuses have a range of meaning associated with them – It could mean the domain holders are having temporary issues or a permanent one. It’s hard to tell.

  • If your ESP’s bounce threshold is less than 7% - Not safe to Email
  • If you are on dedicated IP or IP pool – Email Slowly
