Every email tool.
One platform.

Most verifiers throw up their hands at catch-all domains and bill you for the 'unknown'. Our deeper inspection layer turns the majority of them into real yes/no verdicts.

Send a single test mail to a unique address and get a per-check report on RFC, MIME, headers, SPF, DKIM, DMARC, rDNS and routing, each tagged pass, warning, or critical.

Both aggregate and forensic DMARC reports parsed for you: no raw XML, no homegrown parsers. Real-time alerts the moment an unauthorized source spoofs your domain.

Drop-in client libraries for Node, Python, Go, Ruby, PHP, Java, .NET, Rust and eight more. Most competitors ship three and call it done.

Industry-lowest 'unknown' verdict rate, so far more of your list comes back actionable. And every unknown you do get back is on the house, never charged.

Feature-equivalent to ZeroBounce, NeverBounce and Kickbox, at a price point built for teams who actually count credits. That's the whole pitch.

Tells you exactly who hosts the inbox: Google Workspace, Microsoft 365, Yahoo, Zoho, Proton, or a self-hosted server.

Catches near-miss domains like gnial.com or hotnail.co and surfaces the most likely correct spelling.

Returns the active MX record that's currently routing mail for the address, handy for SEG and ESP detection.

Pulls first and last name out of the local-part when one is encoded, so you can personalize without a separate enrichment hop.

Infers gender from the parsed first name: opt-in, off by default, and only surfaced when the signal is strong.

Reverse the flow: hand us a name and a domain, get back the verified business address in the same call you'd verify it in.

Beyond the categorical verdict, every address gets a numeric score so you can segment, throttle, or warm up by quality band.

We open a live SMTP conversation with the mail server to confirm the inbox actually accepts mail, no shortcuts, no guessing.

RFC-compliant local-part and domain validation runs first so malformed addresses never hit the network or cost a credit.

Confirms the domain exists, resolves, and is configured to actually receive mail before we attempt an inbox conversation.

Domains without explicit MX records still verify cleanly: we fall back to RFC-5321 implicit MX rules where competitors error out.

Proprietary retry logic that defeats greylists on the first lookup window, no minutes-long timeouts, no false unknowns.

Catches mailinator, guerrillamail, 10minutemail and the entire throw-away-mailbox economy in one filter.

Flags catch-all domains that say yes to every SMTP probe but still soft-bounce on real send, the silent reputation killer.

Identifies Gmail, Yahoo, Outlook and the rest of the free-mail crowd, useful for B2B-only segmentation.

Flags shared mailboxes (info@, sales@, support@, admin@) that won't drive 1:1 engagement metrics.

Spots the + tag separator and other suffix patterns inside the local-part, so you can deduplicate at the human-identity level.

Catches inboxes currently over quota: they'll accept the SMTP handshake but bounce the actual delivery within minutes.

Continuous monitoring across 30+ major DNSBL and reputation lists. The instant your domain or IP shows up, you know.

Seed a campaign across Gmail, Outlook, Yahoo and iCloud accounts. See exactly which providers route you to spam, before a single real send.

Gradual, automated warmup schedules for new sending domains so you build reputation instead of burning it on day one.

Catches misaligned, expired or missing authentication records before they degrade your Gmail tab placement.

Run a real test send through your production pipeline and get a full deliverability report back, not just metrics, but the next action to take.

Spin up as many Public or Private keys as you need, in Live or Test mode, and revoke any one of them with a click.

HubSpot, Mailchimp, Salesforce, Brevo, ActiveCampaign, Zapier, Make. Connect once and verify inside the tool you already use.

Pick the exact columns, filters and segments you want (CSV, JSON or webhook payload) without spreadsheet acrobatics afterwards.

Pool credits, share verified lists, and keep a single source of truth across marketing, RevOps and engineering.

Push job completion, blacklist hits, and DMARC events straight into your stack, no polling loops, no cron jobs.

Duplicate addresses across your uploaded lists are stripped before they ever cost you a credit.

Synchronous single-address lookups and async bulk jobs run through the same endpoint with the same auth, no second integration to maintain.

Quality drift across lists and over time, surfaced as charts instead of buried in CSVs, so you spot list rot before it spikes your bounce rate.
