Verify is for addresses that did not come from Argorant. An old CRM export, a list you inherited, a single address someone gave you at a conference.
- Open Verify in the sidebar.
- For a single address, paste it and check it directly.
- For a list, upload a CSV with a column of email addresses.
- Read the result per address: valid, invalid, or catch-all.
The three outcomes mean exactly what they say. Valid means the address accepts mail. Invalid means it does not, and sending to it is how sender reputation gets damaged. Catch-all means the mail server accepts everything it is offered, so no vendor can prove the individual mailbox exists. We label catch-alls honestly rather than quietly counting them as valid, and you decide whether to include them.
This is the same verification that runs on Argorant exports, where every address is checked live at download time or served from a check within the last 60 days. The difference is only the input: your list instead of ours.
The verifier is also available from the CLI with argorant verify email@company.com and from the API at /api/mcp/email/verify, which is the usual way to wire it into an existing pipeline.
