Data Services
Data services are pay-per-use features charged separately from your mailer per-piece costs. You only pay for what you use - no monthly quotas or minimums.
Current per-use rates at thanks.io/pricing.
In the dashboard, every paid lookup is something you choose: each one asks you to confirm with its fee before anything runs (a whole-list search states the most it can cost), and a CSV upload runs a lookup only when you tick it under Paid data lookups (optional). Paid lookups need a card on file and a balance that isn't below $0; when either is missing, the lookup explains why and links to Settings → Payment Method instead of running. See Mailing Lists Overview.
Lead Feeds (people showing intent)
Finds consumers or businesses who are actively researching what you sell, filtered by interest, intent strength, location and (for consumers) home, finance and demographic details, and adds them to a mailing list. Buy a batch once, or keep a feed running that adds fresh leads daily or weekly. You can preview how many people match, with a partly hidden sample, for free before buying.
Charged per lead added, and only for people not already on the list. A purchase or run that adds nobody costs nothing, and the setup and its confirmation show the per-lead price and the most you can be charged before anything is bought. Lead feeds are available from the dashboard only. See Lead Feeds.
An identical one-time lead purchase from the same account is refused within 24 hours of the first one, so a double click can't buy the same leads twice. Details in Duplicate purchase protection.
Address Append (email → physical address)
Converts a known email address into a physical mailing address. Useful for e-commerce operators, insurance agents, real estate professionals, and anyone who has a database of contacts with email addresses but no physical street address on file. Match rate is typically 60-80%.
The videos on this page were recorded on an earlier layout of the dashboard, so some screens and names may differ from what you see today.
Charged per successful lookup. See thanks.io/pricing for current rates.
The same lookup is available from the HubSpot app's mailing list card for a contact that has an email but no street address. The HubSpot Add to Mailing List workflow action runs it unless the step's Email to Address lookup setting is turned Off, and only for a record missing its street address or postal code.
Email/Phone Append (physical → email or phone)
Converts a physical mailing address into an email address or phone number. Also powers the Append on Scan automation - when a recipient scans your QR code, their email or phone is automatically appended to their recipient record.
On a mailing list, run it as Search phone & email: for one recipient from their row menu, for selected rows from the selection toolbar, for the recipients matching an active search or filter with Append filtered recipients in the list's ⋮ menu, or for the whole list with Append entire list. Each run confirms the number of recipients it will search and the most it can cost before anything is charged. See Paid data lookups.
Charged per successful lookup.
Radius Address Search (Neighbor Blast)
Finds all deliverable addresses within a radius of a given property. Used by real estate agents for Just Listed / Just Sold campaigns and local businesses targeting nearby households.
Charged per address returned. A Radius Search mailing list purchase buys at most 2,500 records at a time. Because the records are charged for whether or not you mail them, a purchase made via the API or Zapier is limited to 5 records while API Test Mode is enabled - dashboard purchases keep the full 2,500 either way.
Because this is a per-record spend, an identical Radius Search purchase from the same account is refused within 24 hours of the first one, and the response returns the mailing list ID from that first purchase so you can use the records you already paid for. Full details in Duplicate purchase protection.
VisitorView (website visitor → physical address)
Identifies visitors to your website and appends their physical mailing address, enabling automated follow-up mail.
See VisitorView Website Retargeting for setup instructions.
Print Protect
An optional anti-smudge coating applied to mailers before printing. Charged per piece. Useful for high-stakes or premium campaigns where print presentation is critical.
