Validate Email DNS API (Including Disposable Emails)

What it does

Email Verification checks whether an email address is valid and deliverable. Send an email, and you get back a boolean data value that tells you whether the address passed verification.

Use disposable_checks when you want to reject known disposable domains before MX verification. It defaults to true, so disposable addresses are filtered automatically unless you turn that check off.

This is useful anywhere you need to reduce bad signups, clean a mailing list, or validate user-entered addresses before sending a confirmation email. Because the response is a simple boolean, it fits easily into signup flows, CRM hygiene jobs, and pre-send validation steps.

If you just need a fast yes-or-no signal on whether an address should be treated as usable, Email Verification keeps the response format minimal and easy to wire into your app.
