filtrat keeps a history of the addresses you've verified. When you check the same address again within 180 days, you get the earlier result back without paying for it again. When you want a fresh answer, you can skip the stored result and run a new check, which is charged like any check.
How the history works
- Every address you verify, in a single check or a bulk job, is added to your history with the date it was checked.
- If you verify it again within 180 days, the result comes from your history: free.
- After 180 days the address is checked again from scratch and charged as normal.
- Skipping the history (Re-check in the app,
skip_cache: truein the API or Clay) always runs a fresh check and is charged as normal. - Asking to resolve a catch-all returns an earlier resolution for free; a catch-all that was never resolved is resolved now for 5.
Your history is your own. Another user checking the same address doesn't use or change it.
In a single check
When a result comes from your history, the banner shows a Free tag. Hover it to see when the address was last checked, for example Last checked 12 days ago.
Next to it is Re-check. Press it to run a fresh test of the mailbox right now. A re-check is a normal verification: 1 if the result is deliverable or invalid, free otherwise.
In a bulk job
Addresses in your file that you verified in the last 180 days are filled in from your history at no cost. Only the new ones are charged.
To test a whole job again, open it and press Re-verify all, or select rows and press Re-verify (N). This starts a new job, named Re-verify: <your file>, that tests every address fresh rather than reading your history. The dialog shows how many addresses it includes, the credit cost and your balance before you confirm. You can limit it to some statuses under Or re-verify only, for example only catch-all and risky rows.
When to re-check
A mailbox can change after it was checked: people leave companies, inboxes get closed, domains change their mail setup. Re-check when:
- A list is more than a few months old and you're about to send to it.
- A deliverable address bounced. See A verified email bounced.
- An address came back Risky. Risky results are free, so trying again later costs nothing and often gets a clear answer.
You don't need to re-check a list you verified last week. The history exists so that checking twice doesn't cost twice.
Repeat lookups in the email finder work the same way: an email you found for the same person at the same domain in the last 180 days comes back free. See Found, catch-all unverified, not found.
