01 Agreement

These Terms of Service (“Terms”) are a contract between you and Letters, Inc. (“Letters”). By creating an account or using the service, you agree to them. If you’re agreeing on behalf of a company, you represent that you have authority to bind it.

Plain-language summary: use Letters fairly, pay for what you use, don’t send spam, and the emails you design are yours. The detail below governs if there’s ever a conflict.

02 Accounts

  • You must be at least 18 and provide accurate account information.
  • You’re responsible for activity under your account and for keeping your credentials secure.
  • Notify us promptly at security@letters.com of any unauthorised use.

03 Acceptable use

You agree not to use Letters to:

  • Send unsolicited bulk email (spam) or violate anti-spam laws such as CAN-SPAM, CASL, or GDPR.
  • Distribute malware, phishing, or deceptive content.
  • Infringe intellectual-property or privacy rights.
  • Reverse-engineer, resell, or abuse the service or its rate limits.

We may suspend accounts that put deliverability, security, or other customers at risk.

04 Your content

You retain all rights to the brand assets you upload and the emails you design. You grant Letters a limited licence to host, process, and display that content solely to operate the service for you.

Exported HTML is yours to use anywhere, with no ongoing obligation to Letters. We claim no ownership over your designs.

05 Billing & plans

  • Paid plans bill in advance on a monthly or annual cycle until cancelled.
  • Upgrades are prorated; downgrades and cancellations take effect at the end of the current period.
  • Fees are non-refundable except where required by law. Taxes may apply.
  • We’ll give at least 30 days’ notice of any price change affecting your plan.

06 Sending & anti-spam

If you use Letters to send, you confirm you have permission to email every recipient and will honour unsubscribe requests promptly. You’re responsible for the content and lawfulness of your messages. We provide deliverability tooling but can’t guarantee inbox placement, which depends on your sending practices and recipient providers.

07 Termination

You can cancel anytime from your account. We may suspend or terminate access for breach of these Terms, non-payment, or risk to the service, with notice where practical. On termination you can export your designs for 30 days, after which data may be deleted per our Privacy Policy.

08 Warranty & liability

The service is provided “as is” without warranties of any kind. To the maximum extent permitted by law, Letters’ total liability for any claim is limited to the fees you paid in the 12 months before the claim. We’re not liable for indirect, incidental, or consequential damages.

09 Changes

We may update these Terms as the product evolves. We’ll post the revised version here and, for material changes, notify you by email or in-app. Continued use after changes take effect means you accept them.
