01 — Check one address
Verify emails in real time or by the thousand. Catch typos, disposable addresses and dead domains before they hurt your deliverability and sender reputation.
Verify
Single addressType any address to see its real result, shown the way the app shows it.
02 — Clean the whole list
The same checks, run over every row. Duplicates and malformed rows are dropped for free before anything is spent.
CSV, TXT or XLSX. We find the email column, remove duplicates and invalid syntax for free, and show what a run will cost before you confirm.
Syntax, domain, mail servers, disposable providers and role accounts. Every verdict comes with the evidence behind it, never a bare score.
Choose which verdicts to keep and export a clean file. The results breakdown shows the whole list at a glance.
03 — Keep track
The clean list from the last step is already here: lists, verdicts, exports and your domains, all in one workspace.

RecipesWhen data arrives from a form, EMCHEQ will verify the address, then send the result to your CRM.
ActiveWhen data arrives from a CSV import, EMCHEQ will verify the list, then send the result to a clean export.
ReadyWhen data arrives from your email platform, EMCHEQ will remove invalid addresses.
Needs connection04 — Protect the sender
Once the list is clean, the next risk is mail that pretends to be you. DMARC tells receivers what to do with it. We show where each domain sits on that ladder and what to publish next. Tests read DNS and mail servers; no message is sent.
What receivers do:
05 — Automate
The same verification, wired into the tools you already use. Pick where addresses come in, what EMCHEQ does, and where the result goes.
06 — Build
Generate an API key on any paid plan and check addresses at signup or inside your sending pipeline. Same engine as the app.
curl "https://api.emcheq.com/v1/verify" \ -H "Authorization: Bearer evk_your_key" \ -H "Content-Type: application/json" \ -d '{"email": "name@example.com"}' # response { "email": "name@example.com", "status": "VALID", "score": 98 }
Principles
Bulk lists are parsed in your browser. Only the addresses you confirm are sent for checking.
Each verdict shows the checks behind it. When something can't be known, we say Unknown.
Mail Security tests read DNS and server responses. No message is delivered during a test.
Duplicates and malformed addresses are removed for free, and you see the credit cost before you start.
07 — Choose
Every plan includes bulk verification. No credit card required to start.
