Every check Mailbeam runs
One POST request triggers up to seven checks in parallel. Here is what each one does, when to use it, and how to integrate it.
Bulk Email Verification API
Submit up to 500,000 addresses in a single API call. Get back per-address scores, status classifications and delivery flags — without a connection timeout.
Real-Time Email Verification API
Verify any email address in under 100ms — fast enough to validate while the user is still on the form. Seven checks in parallel, one structured result.
Disposable Email Detection API
Block Mailinator, YOPmail, Guerrilla Mail, and 50,000+ other throwaway services with a single boolean in the verify response.
SMTP Email Verification API
An MX record confirms the domain can receive email. SMTP verification confirms the specific mailbox exists. Mailbeam does both in a single API call.
Catch-All Email Verification API
Corporate domains often accept all email. Mailbeam detects that behaviour explicitly and tells you the verdict is unverifiable, with a capped 0–100 score, instead of reporting a confident pass it cannot back.
MX Record Verification API
MX records tell you whether a domain has mail infrastructure. Mailbeam checks this as the first pass in every verification and returns the result in a single API call.
Syntax Email Validation API
Client-side regex catches obvious mistakes. Server-side RFC 5322 validation catches the edge cases — and can't be bypassed.
Domain Email Verification API
Verify the domain side of an email address: is the domain active, is it a free provider, is it a company domain, or is it catch-all? All from one API call.
Role-based email detection API
Shared inboxes like info@ and sales@ are not people. Flag them at capture so you can gate signups, adjust lead scores, or suppress them from cold sends.
Email Typo Correction API
A single mistyped domain means a signup that never activates. Return an instant 'did you mean' suggestion so the user corrects it in one tap.
Email Deliverability Scoring API
A pass/fail verdict throws away nuance. Get a 0-100 score that blends every check, so you set the risk threshold that fits your funnel.
Spam Trap Detection API
One spam trap in a send can get your domain blocklisted. Screen for high-risk addresses before you press send, not after the damage is done.
