Verified at export
Emails checked the moment you download them, not guessed last quarter.
Most databases hand you addresses that were 'verified' whenever the record was collected, then quietly go stale. Argorant checks every contact live at the moment of export, so the list you load into your sequencer works today, and the bounces that hurt your sending reputation never reach your file.
Checked live at export · Catch-all domains flagged · Checked again at every export
How verification works
A real mailbox check, not a guess.
No pattern guessing: every address is checked to see that its mailbox exists and accepts mail, and domains that accept every address are flagged.

Honest statuses
Valid, catch-all or invalid. Never a shrug.
Every contact carries a clear status, not a vague confidence score: valid is safe to send, catch-alls are flagged for your call, invalid never exports.

Christian Schmidt & Mike Klaßen, Co-Founders & Owners, Boldbrands · GermanyWhat it's worth
Lower bounces, a healthier domain, more replies.
Stale lists bounce at 15 to 20% and hurt deliverability. Verifying at export drops hard bounces toward 1% and keeps your sender reputation intact.

Connecting Claude to a B2B contact database

How to build a targeted B2B list by industry and seniority
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.

Why verified-at-export beats verified-at-collection
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.
