Find companies that fit your offer and the people who decide. Get work emails checked live at export — in Argorant or the AI you already use.
One account. Use the app, your agent, or both.
Teams building outbound on Argorant







565.8M contacts · 184 countries · work emails checked at export
Describe who you sell to, watch the number move, and export contacts that were checked on the way out — straight into the tool you already use.


Plain English, no taxonomy to learn. The count moves while you narrow it, and counting never costs a credit.





Every mailbox is checked against the receiving server the moment you export. Anything unconfirmed is filtered out and costs nothing.

Push straight into your CRM or sequencer, or let an agent pull it over MCP. The checks happen before the row leaves us.




Find the people you want to reach with Claude, ChatGPT or Codex. Then push the verified contacts into your connected sequencer or CRM from Argorant. A CSV is an option, not the finish line.

Same data, same checks, our hands: we map your market, build the sending setup, write the outreach and run it. You get the replies and the meetings, not another tool to learn.

Not the feature list. What you sign, and what it costs when the data is wrong.
Straight from the verification pipeline, not a figure we typed in once.
Verify your email for 100 contact credits, once. Use the app or your AI, then choose wallet credits or a subscription when you need more. Nothing renews automatically from signup.

A practical walkthrough of agent-driven list building: connect Claude to Argorant over MCP, scope a list with free counts and previews, then reveal and export only what survives scrutiny.
A field guide to list definition: why industry filters lie, why seniority is a pattern set rather than a dropdown, how to size a list backward from sending capacity, and the preview-first workflow that catches bad filters before you pay for them.
B2B contact data decays the moment it's collected. Here's why the timing of verification matters more than the method, what an SMTP probe actually proves, and how pay-per-valid pricing changes the buyer's math.
565.8M contacts, with work emails checked before export. Free to start — no annual contract.
Most B2B contact databases describe themselves as “verified.” The word usually means one of three very different things. Sometimes it means an email address was syntactically plausible when it was added. Sometimes it means a pattern was inferred from a company’s known format — first.last@company.com — and labeled “high confidence” without ever being tested. And occasionally it means the address was actually checked against the receiving mail server at some point in the past. The difference matters, because the only verdict your sequencer cares about is whether the mailbox accepts mail today.
Email data decays fast. People change jobs, companies migrate mail systems, inboxes get deactivated, and security gateways change how they answer. A list verified six months ago is not a verified list; it is a historical record. That decay is why teams that buy “verified” data still see double-digit bounce rates — and why bounce rates, not database size, are what actually break cold-email deliverability. Mailbox providers watch your bounce behavior, and a few bad sends can sink an entire domain’s reputation.
Argorant’s answer is to move verification to the only moment where it can be honest: the export. When you download a list, every email in it is checked live against the recipient’s mail server with an SMTP probe — a conversation that asks whether the mailbox exists without sending a message. Addresses that fail are filtered out of your file and cost zero credits. Catch-all servers — domains that accept everything and therefore can’t give a definitive answer — are flagged separately, and you decide at export time whether to include them.
That mechanism is also what makes pay-per-valid pricing possible. Because verification happens at delivery, we can charge only for rows that pass — instead of selling you a static database and letting the decay be your problem. It changes the economics of list building: the meaningful cost of a data provider is never the sticker price, it’s the cost per contact you can actually reach.
The same verification engine is exposed to software, not just humans. A REST API, an MCP server, and a CLI give AI agents and scripts governed access to search, count, and export — with masked previews, plan-scoped rate limits, and credit metering, so an agent can build a verified list overnight without ever overrunning your budget. If you want the full methodology — probe behavior, catch-all handling, verify-at-export, and what “valid” means precisely — it’s documented on how we verify, and the broader playbooks live in our guides.
