Every email address that you verify, will come back with a result that is either ‘deliverable’, ‘undeliverable’, ‘risky’ or ‘unknown’. Below is a short explanation of what each means:
deliverable- The recipient’s email provider has confirmed that the email address exists, it is safe to send.
risky- The email address may result in a bounce or low engagement. Risky addresses: Accept All, Full Mailbox or Disposable.
undeliverable- The address is either syntactically incorrect or does not exist.
unknown- We were unable to receive a response from the email provider.
Additionally to the status of your results, Bouncer will provide you with a reason for the results:
low_deliverability- Email address appears to be deliverable, but deliverability cannot be guaranteed (in most cases it is caused by catch_all / accept_all configuration of recipient’s server or full mailbox).
low_quality- Email address has quality issues that may make it a risky or low-value address (in most cases it is caused by the fact that it is a disposable/temporary email).
invalid_email- Specified email doesn’t have a valid email address syntax.
invalid_domain- Domain for email does not exist or has no valid DNS records.
rejected_email- Email address was rejected by the SMTP server, email address does not exist.
dns_error- We were unable to resolve DNS records or domain is misconfigured.
unavailable_smtp- SMTP server was unavailable to process our request.
unsupported- Email hosted by an unsupported email service provider.
timeout- Verification required more time than was available.
unknown- An unexpected error has occurred.

Did You Mean
If the email address you have provided seems to be undeliverable or of low quality - Bouncer may find a suggestion of a correct one and return it in the didYouMean field.
Please note it was not fully verified, so you might want to run a verification of the suggested email address.
Score represents chance for successful delivery of email. 100 means 100% chance of delivery, given sending infrastructure has good reputation.
Empty value means that it wouldn’t make sense to evaluate score, for example in the case of timeout.
If toxicity has been checked this flag will have one of the values “yes”, “no”, “unknown”. Meaning of which are as follows:
- yes - email or its domain has been found in one of our lists which indicate that it was involved in spam, abusing, is owned by a litigator or a complainer, or is a spam trap
- no - it has not been found on any of our email toxicity lists
- unknown - it has not been found on any of our lists, although it may be ambiguous
