#1 Email Verification API to verify the existence, validity & quality of any email address.

Our Email Verification API performs a comprehensive validation of email addresses in real-time and conveniently. Verify the email addresses coming from new user registrations, reduce email bouncing, block spam, and more.
#### Our email validation service via API calls checks:
**Syntax**
Check if the email address conforms to the IETF standards by using a complete syntactic email validation engine.
**If the address is branded**
Check if the address is custom and linked to a business email account or if it is generic and coming from a free email service.
**If the address is disposable**
Check if the email address is supplied by a known disposable email address provider such as Mailinator, 10MinuteMail, GuerrillaMail, and 2,000+ more.
**Mail server existence**
Check for the availability of email addresses’ corresponding domains by ensuring the existence of DNS MX records.
#### Practical usage
**Improve marketing campaign results**
In email marketing, it is important that the emails you send are verified, validated, and received by customers. One of the most common causes of email bouncing is sending to unverified email addresses.
**Segment potentially dangerous emails**
Keep potentially unverifiable email addresses such as disposable ones out of your contact list. Users signing up for freemium services with disposable email addresses may turn out to be abusers.
