Sample links are single-use and time limited on purpose: they carry a personalized list of contacts, so they behave like a key rather than a bookmark. Four messages cover every failure.
This link isn't valid
This link isn't valid.
The token in the URL does not match anything. Usually the link was broken across two lines by a mail client, or only part of it was copied. Go back to the original email and click the link rather than pasting it.

The sample is now attached to an account, which is the intended end state. Sign in at app.argorant.com/login with the address the link was sent to, and the sample is waiting inside. If sign-in with that address fails, use 'Forgot password' rather than registering a second account.
The link expired
That link expired - request a fresh one.
This link expired - request a fresh one from the page.
Claim links live for a limited window. The expired page itself offers to send a new one, and the new link lands in the same mailbox.
A fresh link was already sent
A fresh link was already sent - check your inbox.
You can only reissue once. Check the inbox, including spam and any shared alias that forwards to it. If it genuinely is not there, mail support@argorant.com from the address the sample was sent to and it gets reissued manually.
Nothing in the sample is lost while you sort the link out. And if it turns out to be faster, you can skip the sample entirely: create a free account, open People search and rebuild the same targeting yourself. Searching and counting are free forever.
