Mailcheck – Objective-C

The Objective-C library that suggests a right domain when your users misspell it in an email address. See the original at

When your user types in "[email protected]", Mailcheck will suggest "[email protected]".

Mailcheck will offer up suggestions for top level domains too, and suggest ".com" when a user types in "[email protected]".


Copy mailcheck.h and mailcheck.m from the Mailcheck folder to your project.

#import "Mailcheck.h"
NSDictionary *result = [Mailcheck suggest:@"[email protected]"]

Result will contain nil if the domain appears to be valid.
Otherwise the suggestion will be a dictionary like this:

{@"address": @"test",
 @"domain":  @"",
 @"full":    @"[email protected]"}

New in 0.2

Now includes a check if the email is valid thanks to

#import "Mailcheck.h"
NSDictionary *result = [Mailcheck check:@"[email protected]"]

Result will contain keys for "valid" and "suggestion"

{@"valid": @(YES),
 @"suggestion": {@"address": @"test",
                 @"domain":  @"",
                 @"full":    @"[email protected]"}}

Supply your own domain lists:

NSDictionary *result = [Mailcheck check:@"[email protected]" domains:@[@""] topLevelDomains:@[@"co"]];

Or add to the default list:

NSDictionary *result = [Mailcheck check:@"[email protected]" extraDomains:@[@""] extraTopLevelDomains:@[@"co"]];

Check the MailcheckDemo or the GHUnit tests in TestMailcheck.m for more usage examples. You can run the tests by loading the demo project and selecting the Tests scheme.
