Need a simple, efficient method to perform email validations on a large scale quickly? Welcome to Bulk Validations!
Our Bulk Validations feature provides a simple, easy-to-follow set of steps for validating a large number of email addresses and retrieving the results quickly. From there, you can take proactive steps to protect the reputation of your sending domain(s) and your IP(s) by removing the invalid email addresses from your mailing lists or contacts. This due diligence, in turn, aids in maintaining an excellent quality of recipients, as well as minimizing bounce and suppression events. We're all about optimizing your sending to help enable the full range of your success!
Note: Bulk Validations feature is only available for paid accounts.

Validations results & risk score explained
Deliverable: An address that has a high likelihood of being legitimate and has passed all validation checks.
Undeliverable: An address that is confirmed invalid and should be discarded from a list or corrected.
Do Not Send: An address that may damage the sender reputation if messages are sent.
Catch-All: The validity of the recipient address cannot be determined as the provider accepts any and all email regardless of whether or not the recipient’s mailbox exists.
- Unknown: The validity of the recipient's address cannot be determined for a variety of potential reasons. Please refer to the associated ‘reason’ array returned in the response.
Low: Likely a legitimate address and sending has a low likelihood of damaging reputation if the address has been obtained with customer consent.
Medium: Addresses that we cannot validate as legitimate but do not have any identifiable issues. These addresses are often role addresses, catch-all domains, or the domain isn’t on our list of trusted domains.
High: An address that has a high risk of damaging sender reputation.
CSV/JSON export explained
address: Email address being validated
did_you_mean: (Optional) Null if nothing, however, if a potential typo is made to the domain, the closest suggestion is provided
is_disposable_address: If the domain is in a list of disposable email addresses, this will be appropriately categorized
is_role_address: Checks the mailbox portion of the email if it matches a specific role type (‘admin’, ‘sales’, ‘webmaster’)
reason: List of potential reasons why a specific validation may be unsuccessful.
result: Either deliverable, undeliverable, catch_all or unknown. Please see the Result Types section below for details on each result type.

root_address: (Optional) If the address is an alias; this will contain the root email address with alias parts removed.
unknown_provider: The MX provider is an unknown provider.
no_mx / No MX host found: The recipient domain does not have a valid MX host.
high_risk_domain: Information obtained about the domain indicates it is high risk to send email to.
subdomain_mailer: The recipient domain is identified to be a subdomain and is not on our exception list. Subdomains are considered to be high risk as many spammers and malicious actors utilize them.
immature_domain: The domain is newly created based on the WHOIS information.
tld_risk: The domain has a top-level-domain (TLD) that has been identified as high risk.
mailbox_does_not_exist: The mailbox is undeliverable or does not exist.
mailbox_is_disposable_address: The mailbox has been identified to be a disposable address. Disposable addresses are temporary, generally one-time use, addresses.
mailbox_is_role_address: The mailbox is a role-based address (ex. support@…, marketing@…).
catch_all: The validity of the recipient address cannot be determined as the provider accepts any and all email regardless of whether or not the recipient’s mailbox exists.
- long_term_disposable: The mailbox has been identified as a long-term disposable address. Long-term disposable addresses can be quickly and easily deactivated by users, but they will not expire without user intervention.
