MailQ helps you spot good, risky and bad addresses before a campaign goes out. Paste one email, get a clear result, and avoid sending to inboxes that are likely to bounce.

This address looks safe to keep on your list.
The checks run in order. If an address fails one, MailQ stops there and tells you why.
Catches typos and malformed addresses, like a missing @ or a domain without a dot.
Looks up the domain's MX records. No mail servers means no mail can be delivered.
Connects to the domain's mail server and asks whether the mailbox exists. Up to three servers are tried. Nothing is sent.
Asks about a random address on the same domain. If that's accepted too, the domain takes everything and the result is marked Risky.
Every result also tells you whether the domain belongs to a known disposable email provider.
No confidence scores to interpret. Each result tells you what to do with the address.
Paste a list into bulk verification and drop undeliverable addresses before they bounce and hurt your sender reputation.
Spot throwaway addresses from disposable email providers before they fill your user base.
Send lists from your CRM, forms or scripts to the verification API and store the verdict next to each contact.
Pro includes an API key for the bulk verification endpoint. Send a JSON list of addresses and get the same detailed result you see in the web app.
