All purchased credits are non-refundable and do not expire. Free credits are redeemable for printing costs only and cannot be refunded or converted to cash. Free credits may be applied to both Free and Subscription accounts.
Thanks.io relies on the United States Postal Service ("USPS") and, where applicable, other third-party carriers and postal services for the transportation and delivery of mail. Once a mailpiece has been transferred to the applicable postal service or carrier, its handling and delivery are outside the direct control of Thanks.io.
Any estimated delivery dates, delivery status information, scans, tracking information, or other postal data provided through the Services are estimates or information received from third parties and are provided for informational purposes only. Thanks.io does not guarantee delivery by a particular date or time or the accuracy or completeness of postal tracking or delivery-status information.
Thanks.io is not responsible for postal delays, missed or inaccurate scans, forwarding, returns, loss, damage, weather-related disruptions, incorrect or undeliverable recipient addresses, or other events occurring after mail has entered the postal system, except to the extent otherwise required by applicable law.
Postal delivery delays, tracking discrepancies, or failure of USPS or another carrier to complete delivery do not, by themselves, constitute grounds for a refund or credit from Thanks.io.
Paid subscription plans automatically renew for the applicable billing period unless canceled in accordance with these Terms.
Monthly subscriptions may be canceled at any time through the Billing section of Your account. Cancellation prevents future renewal charges and does not retroactively refund charges from prior billing periods.
Annual subscription plans are offered as a twelve-month commitment and may include discounted pricing or other benefits. Cancellation of an annual subscription takes effect at the end of the current annual term. To prevent renewal for an additional annual term, You must request cancellation before the applicable renewal date using the cancellation method provided by Thanks.io.
You are responsible for managing Your subscription and maintaining accurate account and billing information. Thanks.io may send billing, renewal, or subscription notices as a courtesy, but failure to receive or review such notices does not extend a subscription term or automatically entitle You to a refund.
Any refund following a subscription renewal is governed by the Refund Policy stated in these Terms.
We send monthly subscription confirmation emails and include clear links to support and cancellation options. As such, clients are responsible for managing their own subscriptions. We do not offer refunds for unused services or retroactive cancellations beyond the current billing period. If a client cancels a subscription shortly after a renewal (typically within 3–5 business days), we may, at our discretion, issue a one-time courtesy refund for that most recent charge.
If an order is canceled, a full refund will be issued to your Thanks.io account within 30 minutes. If you prefer a refund to your credit card, please note that these requests are handled on a case-by-case basis. In such cases, any applicable merchant processing fees will be deducted from the refund amount.
All Reverse Append Services and Mailing List Purchases made through Thanks.io are non-refundable. Upon completion of your purchase, you will receive immediate access to the data, which is considered a final sale. We do not offer refunds, exchanges, or cancellations for these services due to their intangible nature and instant delivery.
Direct mail marketing is most effective when done in bulk. If you're considering mailing individual pieces and are concerned about delivery times or minor handling effects (such as bent corners), please note that direct mail marketing is optimized for larger, targeted campaigns to achieve high impact and engagement.

The term ("Term") of this Agreement will commence once You accept this Agreement as provided above. The Agreement will remain in effect until terminated by You or Thanks.io in accordance with this Section 2.
You may terminate this Agreement for any reason or no reason at all, at Your convenience, by closing Your account for any Service for which we provide an account closing mechanism.

If Thanks.io determines that providing advance notice would negatively impact Thanks.io's ability to provide Services, Thanks.io may suspend Your right and license to use any or all Services or terminate this Agreement immediately without notice.
We may suspend Your right and license to use the Service or terminate this Agreement in its entirety (and, accordingly, Your right to use the Service), for cause effective as set forth below:
Immediately upon our notice to You in accordance with the notice provisions set forth in Section 9 below if: (i) You violate any provision of the Acceptable Use Policy or we have reason to believe that You have violated the Acceptable Use Policy; (ii) there is an unusual spike or increase in Your use of the Services for which there is reason to believe such traffic or use is fraudulent or negatively impacting the operating capability of the Service; (iii) we determine, in our sole discretion, that providing the Services to You could create liability for Thanks.io or other users of the Services; or (iv) we determine that You have violated any provision of this Agreement.
Immediately and without notice if You are in default of any payment obligation with respect to any of the Services or if any payment mechanism You have provided to us is invalid or charges are refused for such payment mechanism.
Five (5) days following our provision of notice to You in accordance with the notice provisions set forth in Section 9 below if You breach any other provision of this Agreement and fail, as determined by us, in our sole discretion, to cure such breach within such 5-day period.
Upon our suspension of Your use of any Services, in whole or in part, for any reason: (i) fees will continue to accrue for any Services that are still in use by You, notwithstanding the suspension; (ii) You will remain liable for all fees, charges and any other obligations You have incurred through the date of suspension with respect to the Services; and (iii) all of Your rights with respect to the Services shall be terminated during the period of the suspension.

All amounts payable by You under this Agreement will be made without setoff or counterclaim and without deduction or withholding. If any deduction or withholding is required by law, You shall notify us and shall pay such additional amounts to us as necessary to ensure that the net amount that we receive, after such deduction and withholding, equals the amount we would have received if no such deduction or withholding had been required.
