Clean lists before every send
SPIRITT runs PureChecker on single addresses or full batches, reads the syntax, domain, mailbox, disposability and risk signals, and routes every contact to the right list. It builds the hygiene workflow once and keeps it running.
What you can do with PureChecker.
Whole files in one pass
Check an import, segment or vendor file in a single batch and get signals for every address.

Questions
PureChecker, with SPIRITT.
01What does PureChecker check?+
Each check returns syntax, domain, mailbox, disposability and risk signals for the address. SPIRITT turns those signals into the keep, fix or drop rules you set.
02Can SPIRITT verify a whole list at once?+
Yes. PureChecker accepts a batch of addresses in one request. SPIRITT splits very large files into batches, tracks progress and merges results back into one clean file or record set.
03Where do the results go?+
Into HubSpot or Salesforce properties, Mailchimp or Klaviyo tags and suppressions, Supabase tables, Google Sheets reports or a downloadable CSV.
04Can verification run continuously?+
Yes. SPIRITT checks new signups, leads or applications on the schedule you choose, so bad addresses are caught before campaigns, onboarding emails or partner access go out.
05What can SPIRITT build around PureChecker?+
A CSV verification tool for your team, a reseller application gate, a lead source quality scorecard, or a migration pipeline that only moves verified contacts.
06What do I need to connect?+
Your PureChecker API key, plus access to the CRM, email platform or sheets where your contacts live.
