Source: https://trysincerely.com/terms Effective August 31, 2026 These terms are an agreement between you and 18191875 Canada Inc. (“Sincerely,” “we,” or “us”) and govern your use of Sincerely at trysincerely.com (the “Service”). By affirmatively accepting these terms or using the Service after acceptance, you agree to them. If you accept for an organization, you represent that you can bind that organization. ## The service Sincerely turns B2B direct mail into software: audiences from your CRM or CSVs, personalized printed pieces produced through third-party fulfillment partners, and measurement of outcomes against holdout groups. We may change or improve features over time; we will not materially reduce the core service you have paid for during a paid term. ## Your data and responsibilities You retain all rights to the data you bring — CRM records, CSVs, brand assets, and message content. You grant us the rights needed to operate the Service on that data (including sharing recipient names and postal addresses with print and mail partners). You are responsible for having a lawful basis to mail the recipients you target, for the accuracy of recipient data, for the content of your mail, and for securing workspace API keys and the systems that use them. An event accepted under a workspace API key is treated as authorized by your workspace until you revoke that key. Revoke a key promptly if it is exposed. Prohibited: unlawful, deceptive, harassing, or hateful mailings; mailing individuals you know have asked not to be contacted; and any use that violates postal regulations. ## Mail fulfillment Physical production and delivery are performed by third-party partners and the postal service. Delivery dates are estimates, not guarantees. Cancellation of a submitted piece is best-effort within the vendor’s cancellation window; once a piece enters production it may not be cancelable. Suppression requests are honored immediately for all future production. ## Disclaimers and liability We provide the Service “as is” and make no express or implied warranties about it. Where the law allows, neither you nor Sincerely will be liable for indirect, incidental, special, or consequential damages. Sincerely's total liability under these terms will not exceed the fees you paid us during the twelve months before the claim. If your recipient data or mail content leads to a claim against us, you will indemnify us for that claim. ## Termination You may stop using the Service whenever you choose. A paid term continues through the end of its billing period. We may suspend or terminate an account that breaches these terms and will give notice when practicable. After termination, we will leave your data available for export for a reasonable period before deleting it. ## General Ontario law and the federal laws of Canada that apply in Ontario govern these terms, without regard to conflict-of-laws rules. If one provision cannot be enforced, the remaining provisions still apply. These terms and any order form make up the entire agreement. We may revise them. We will notify you of a material change, which will take effect at your next renewal or thirty days after notice, whichever comes later. ## Fees and billing Fees are as posted on our [pricing page](https://trysincerely.com/pricing) or as otherwise agreed in writing. A paid package grants a stated number of credits that cover fulfillment, postage, AI-assisted writing, measurement, and operations. Mail types use the credit weights posted when you buy. Monthly credits expire at monthly renewal. Annual credits are available for the full paid year and expire at annual renewal. Pilot credits do not expire. Credits have no cash value and are nontransferable. Prepaid top-up credits are required for usage beyond a subscription pool. Top-up credits do not expire. An active recurring plan is required to buy or use top-up credits and gift funds. Gift + note uses 10 credits plus the approved catalog price, and that dollar amount must be present in the workspace's prepaid gift balance before fulfillment. Gift funds do not expire. Pilot cannot buy or send gifts. Sincerely does not create a negative credit or gift balance and does not invoice overages after fulfillment. Vendor-confirmed cancellations restore reserved credits and, for an unfulfilled gift, reserved gift funds. If the source subscription term has ended, returned subscription credits become a cancellation adjustment valid for 30 days. Unused adjustment credits expire after that period. Prices are pretax; applicable tax is calculated and itemized separately. Piece caps apply per paid term, and fulfillment pauses rather than exceed available prepaid funding or the cap. Same-cadence upgrades are prorated for the exact seconds remaining in the term. Downgrades and cadence changes begin at renewal. Annual purchases are prepaid. Canceling stops renewal; access continues through the paid term. We may change prices with notice effective at your next renewal. Except where required by law, package, top-up, and gift-fund payments are non-refundable. A refund we approve for a wholly unused purchase removes the matching credits or gift funds. A partial refund, payment dispute, or refund after any of the purchase has been used may hold fulfillment until the balance is reconciled. ## Measurement Readouts, lift estimates, and confidence intervals are statistical estimates produced from your campaign design. We work to make them honest — including telling you when a result is not statistically ready — but we do not guarantee business outcomes, response rates, or revenue. ## Intellectual property We own the Service and everything in it except your data. You may not copy, resell, or reverse-engineer the Service. Feedback you give us may be used without obligation.
