Generic email validator

You can do only using html:

<md-input-container class="md-icon-float md-block" flex-gt-sm>
    <label>Email</label>
        <input md-input
            id="contact-email"
            type="text"
            ngControl="email"
            #email="ngForm"
            [(ngModel)]="contact.email"
            required
            pattern="^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,6})+$">

    <div class="md-errors-spacer" [hidden]="email.valid || email.untouched">
        <div class="md-char-counter" *ngIf="email.errors && email.errors.required">
            Email is required
        </div>
        <div class="md-char-counter" *ngIf="email.errors && email.errors.pattern">
            Email is invalid
        </div>
    </div>
</md-input-container>

For angular 4 and above:

According to This you can use "email validator".

Example:

If you use template-driven forms:

<input type="email" name="email" email>
<input type="email" name="email" email="true">
<input type="email" name="email" [email]="true">

If you use model-driven forms(aka ReactiveFormsModule) use Validators.email:

this.myForm = this.fb.group({
    firstName: ['', [<any>Validators.required]],
    email: ['', [<any>Validators.required, <any>Validators.email]],
});

Old answer: You can use angular 2 FormGroup,

By using validators.pattern and regex like this:

 let emailRegex = '^[a-z0-9]+(\.[_a-z0-9]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,15})$';
 this.myForm = this.fb.group({
        firstName: ['', [<any>Validators.required]],
        email: ['', [<any>Validators.required,  <any>Validators.pattern(emailRegex) ]],
 });
