Get Started

dotnet add package Unclaimable.Email --version 1.0.0

Check an email address

using Unclaimable.Email;

var checker = new EmailChecker();
var result = checker.CheckExistingAddress("hello@example.com");

Configure protected and issuing domains

var options = new EmailOptions();
options.ProtectedDomains.Add("example.com");
options.IssuingDomains.Add("example.com");

var checker = new EmailChecker(options);
var result = checker.CheckNewAddress("bluegarden@example.com");

Use policy presets

var registration = EmailOptions.ForUserRegistration();
var organization = EmailOptions.ForOrganizationEmail("example.com");
var issued = EmailOptions.ForIssuedAddresses();

var checker = new EmailChecker(registration);

Domain and Identity Controls

EmailOptions.LocalPartOptions exposes the Unclaimable username and identifier matching configuration for the mailbox local part. Domain policy includes normalized DNS/IDN handling, protected-domain rules, configurable lookalike detection, and issuing-domain checks.

var options = new EmailOptions
{
    AllowIssuingDomainSubdomains = false,
    EnforceIssuingDomainsForExistingAddresses = true
};
options.IssuingDomains.Add("example.com");

Result Diagnostics

EmailResult includes IsAllowed, IsSuspiciousDomain, local-part findings, domain lookalike kind, and protected-domain information.

Compatibility

Targets netstandard2.0, suitable for shared application libraries and mobile, web, desktop, and server projects.
