Check if the email address is RFC822 and RFC2822 compliant
DNS Validation
Check if the email domain resolves correctly and has working MX (mail exchanger) records
Typo Fixing
Automatically fix common domain, TLD (top-level domain) and freemail address typos
Freemail Filtering
Determine if the email address is a freemail address, i.e. from a service providing free email
Disposable Filtering
Determine if the email address is associated with a disposable, temporary or darknet email service
Role Detection
Check if an email address is personal or role based
Note:
This API does not perform any SMTP based username/mailbox verification.
This means it cannot determine if a specific username is registered or not with the email provider.
To achieve this you can utilize the Email Verify API
Is this a valid email address. To be valid an email must have: correct syntax, a registered and active domain name, correct DNS records and operational MX servers
email
string
The complete email address. If you enabled the 'fix-typos' option then this will be the corrected address
domain
string
The domain name of this email address
provider
string
The domain name of the email hosting provider
mx-ip
string
The first resolved IP address of the primary MX server, may be empty if there are domain errors present
is-freemail
boolean
True if this address is from a free email provider
is-disposable
boolean
True if this address is a disposable, temporary or darknet related email address
is-personal

True if this address likely belongs to a person. False if this is a role based address, e.g. admin@, help@, office@, etc.

no-service - the domain owner has indicated there is no mail service on the domain (also known as the 'Null MX')
no-mail - the domain has no valid MX records so cannot receive email
mx-invalid - MX records contain invalid or non-conformant hostname values
mx-bogon - MX records point to bogon IP addresses
resolv-error - MX records do not resolve to any valid IP addresses
