# you can import any of these validators or write your own validator
# (
#     BlackDomainListValidator,
#     DomainExtensionValidator,
#     LengthValidator,
#     MultiDotValidator,
#     SafeDomainValidator,
#     SafeDomainValidatorOnline,
# )

email = Email("hello@gmail.com")
black_email_list = [
    "xyz-mail.com",
    "tempmail.com",
    "temp.com",
    "mail-temp.org",
    # ...
]
validators = [
    BlackDomainListValidator(black_email_list),
]

verifier = EmailVerifier(email)
verifier.verify(validators)

prevent raise exception

from email_domain_verification import Email, EmailVerifier
from email_domain_verification.validators import BlackDomainListValidator

email = Email("hello@gmail.com")
black_email_list = [
    "xyz-mail.com",
    "tempmail.com",
    # ...
]
validators = [
    BlackDomainListValidator(black_email_list),
]

verifier = EmailVerifier(email)
validated: bool = verifier.verify(validators, raise_exception=False)
# validated == True => email is safe | validated == False => email is unsafe

Create Custom Validator

from email_domain_verification import Email, EmailVerifier
from email_domain_verification.interfaces import ValidatorInterface
from email_domain_verification.validators import LengthValidator


class CustomValidator(ValidatorInterface):
    __criterion: typing.Type

    def __init__(self, criterion: typing.Type) -> None:
        self.__criterion = criterion

    def validate_criterion(self) -> None:
        # validate __criterion
        pass

    def check(self, email: Email) -> bool:
        self.validate_criterion()

        # check email.value
        # example: len(email.value) > self.__criterion: return True
        validate = True
        if not validate:
            raise ValueError("The Error Message")

        return True


email = Email("hello@gmail.com")
validators = [
    BlackDomainListValidator(black_email_list),
    CustomValidator(10),
]

verifier = EmailVerifier(email)
verifier.verify(validators)
