Email Address Validator
Validate email syntax, check MX records, and flag disposable domains.
What is Email Address Validator?
Email validation has three layers: syntax (does it look like an email?), DNS (does the domain have MX records to accept mail?), and reputation (is this a disposable/throwaway service?). Truly verifying deliverability requires sending a test message — but checking syntax + MX + disposable catches 90% of bad addresses without bothering the recipient.
Frequently asked questions
Why not actually send a test email?▼
Sending to verify causes spam complaints and damages your sender reputation. MX + disposable checks are the safer signal.
