Email Verification Status | Description | Can Send Email? |
Deliverable | Valid email | Yes |
Undeliverable | Not a valid email | No |
Accept-all | Unverifiable | Maybe* |
Unknown | Unable to verify | Maybe* |
Maybe* - Depending on the overall list quality and the email service provider you are using, you can decide whether to send emails to these addresses. If you are using a third-party ESP, it is better to avoid sending emails to these addresses.
Deliverable
The email address exists and accepts emails, confirmed through SMTP communication. These addresses are valid and safe to send emails to.
Undeliverable
The email address either does not exist or does not accept emails. Sending emails to invalid addresses will result in a bounce.
Accept-all
These addresses cannot be verified as their mail server accepts both valid and invalid addresses, making definitive verification impossible.Should I send emails to accept all results?
We recommend testing your accept-all email addresses by sending a small batch of email campaigns to avoid a high bounce rate.
Unknown
These emails could not be definitively verified as their mail servers were not reachable during verification. Unknown addresses are checked multiple times from different locations at varying intervals before arriving at this result.Disposable
These are temporary email addresses and should not be mailed as there is a very high chance of the email bouncing.- Y and N: Indicate "Yes" and "No."
- ISP: "Yes" if the email is from a known ISP, such as Gmail or Hotmail.
- Syntax Error: "Yes" indicates an incorrect email format.
- Role: Role-based emails belong to groups, companies, or departments.
- Disposable: Temporary email addresses that typically result in a high bounce rate.
- Trap: These are spam traps—seemingly valid addresses flagged due to suspicious activity.
