Terms of Service

Last updated: 24 June 2026

1. Introduction

These Terms of Service ("Terms") govern your use of the sendcheck.io website and service (the "Service"), operated by Sendcheck Ltd ("sendcheck.io", "we", "us", or "our"), a company registered in England and Wales under company number 17297971, with its registered office at 71-75 Shelton Street, Covent Garden, London, WC2H 9JQ.

By creating an account or using the Service, you agree to these Terms. If you do not agree, you must not use the Service. Please also read our Privacy Policy, which forms part of these Terms.

2. The Service

Sendcheck.io is an email analysis service that reviews marketing emails and provides automated checks, AI-generated feedback, deliverability analysis, and related insights. The Service is designed to help you identify potential issues and improve your emails before you send them.

We may add, change, or remove features of the Service at any time, including for users on any plan. We aim to give reasonable notice of significant changes where practical.

3. Accounts

To use the Service you must create an account and provide accurate, current information. You are responsible for:

  • Keeping your login credentials secure
  • All activity that occurs under your account
  • Ensuring your use of the Service complies with these Terms and applicable law

You must be at least 18 years old, or the age of majority in your jurisdiction, and using the Service for business or professional purposes. The Service is not intended for consumers using it for personal, household purposes.

4. Acceptable use

You agree not to:

  • Use the Service for any unlawful, fraudulent, or abusive purpose
  • Submit content you do not have the right to submit
  • Attempt to circumvent usage limits, plan restrictions, or access controls (including creating multiple accounts to obtain additional free scans)
  • Resell, sublicense, or provide the Service to third parties except as expressly permitted by your plan
  • Reverse engineer, scrape, overload, disrupt, or attempt to gain unauthorised access to the Service or its infrastructure
  • Use the Service to process content that is illegal, harmful, or infringes the rights of others

We reserve the right to investigate and take action — including suspending or terminating your account — in response to any breach of this section.

5. Your content and third-party data

You retain ownership of the email content you submit ("Your Content"). You grant us a limited licence to process Your Content solely to provide the Service to you.

You are responsible for Your Content, including any personal data of third parties it contains (such as your subscribers' details in personalisation fields). You confirm and warrant that:

  • You have the right to submit Your Content
  • You have a lawful basis to share any third-party personal data within it for the purpose of scanning
  • Your Content does not infringe any law or the rights of any person

You agree to indemnify and hold us harmless against any claim, loss, or liability arising from Your Content or your breach of this section.

6. Plans, payment, and refunds

6.1 Plans

The Service is offered on a free plan and various paid plans (including subscription and lifetime plans), each with its own features and usage limits as described on our pricing page. Usage limits (such as the number of scans per month) apply to all plans, including lifetime plans.

6.2 Payment

Paid plans are billed through our payment provider, Stripe. By purchasing a paid plan, you authorise us to charge the applicable fees. Subscription plans renew automatically unless cancelled before the renewal date.

6.3 Subscription cancellation

You may cancel a subscription at any time. Cancellation takes effect at the end of your current billing period; you retain access until then. We do not provide partial refunds for unused portions of a billing period unless required by law.

6.4 Refunds

Except where required by law, fees are non-refundable. Any refund or "cooling-off" rights that apply to you by law are not affected by this clause.

7. Lifetime plans

Lifetime plans are subject to the following terms, which you accept when purchasing one. Please read this section carefully.

7.1 "Lifetime" means the lifetime of the Service

A lifetime plan grants access for the operational lifetime of the Service, not your own lifetime, and not indefinitely or in perpetuity. If we cease to operate the Service, discontinue it, or it is otherwise no longer available, your lifetime access will end. (See 7.4 for what happens in that case.)

7.2 Usage limits apply

Lifetime plans are subject to the fair-use and usage limits stated on our pricing page (including, currently, a monthly scan limit). Lifetime does not mean unlimited. We may adjust fair-use limits from time to time on reasonable notice to keep the Service sustainable.

7.3 The Service may change

Lifetime access entitles you to the Service as it evolves. We may add, modify, migrate, or remove features over time. We do not guarantee that any specific feature will remain available for the duration of a lifetime plan.

7.4 Discontinuation of lifetime plans

We reserve the right to discontinue lifetime plans, or the Service as a whole, where we reasonably consider it necessary — including for commercial sustainability, technical, legal, or operational reasons. If we discontinue lifetime plans as a class (as opposed to terminating an individual account under 7.5):

  • Lifetime customers who purchased their plan less than 24 months before the discontinuation date will be offered, at our discretion, either a pro-rata credit or a discounted migration to an equivalent subscription plan.
  • Lifetime customers who purchased their plan 24 months or more before the discontinuation date are deemed to have received fair value and will not be entitled to compensation.
  • If the Service shuts down entirely, access ends for all users; this clause governs any goodwill offered to lifetime customers but does not create an entitlement beyond what is stated here.

7.5 Termination of individual lifetime accounts

Notwithstanding anything else in this section, we may suspend or terminate an individual lifetime account immediately and without refund or compensation where:

  • You breach these Terms (including the Acceptable Use section)
  • You engage in fraud, abuse, chargebacks, or attempts to circumvent usage limits or resell the Service
  • Your use imposes costs or risks on us that are materially disproportionate to your plan
  • We are required to do so by law

7.6 No reliance on perpetual access

You acknowledge that you are not purchasing a guarantee of perpetual or unlimited access, and that the fee for a lifetime plan reflects the terms in this section. You should not purchase a lifetime plan on the assumption that it will be available forever or without limits.

8. Nature of the Service — no guarantee of outcomes

The Service provides automated checks, AI-generated feedback, and analysis intended to assist you. It is a tool to support your judgement, not a substitute for it.

You acknowledge and agree that:

  • The Service does not guarantee that your emails will reach the inbox, avoid spam folders, perform well, convert, or be free of errors.
  • Deliverability, spam, and inbox-placement assessments are indicators and estimates based on the information available to us, and do not guarantee any particular outcome at any mailbox provider.
  • AI-generated suggestions are recommendations only; you are responsible for reviewing and deciding whether to act on them.
  • The Service may not detect every issue in an email, and the absence of a flagged issue does not mean an email is error-free.

You remain solely responsible for the emails you send and their consequences.

9. Availability

We aim to keep the Service available and reliable, but we do not guarantee uninterrupted or error-free operation. The Service is provided "as is" and "as available". We may suspend the Service for maintenance, updates, or reasons beyond our control.

10. Limitation of liability

Nothing in these Terms excludes or limits our liability where it would be unlawful to do so — including for death or personal injury caused by our negligence, or for fraud.

Subject to that:

  • We are not liable for any indirect, incidental, consequential, or special losses, or for loss of profits, revenue, data, goodwill, or business opportunity, arising from your use of (or inability to use) the Service.
  • We are not liable for any loss arising from your reliance on the Service's checks, feedback, or analysis, or from any email you send.
  • Our total aggregate liability to you, for all claims arising out of or relating to the Service or these Terms, is limited to the greater of (a) the total fees you paid us in the 12 months preceding the claim, or (b) £100.

These limitations apply to the fullest extent permitted by law and reflect the price of the Service and the allocation of risk between us.

11. Indemnity

You agree to indemnify and hold harmless Sendcheck Ltd and its officers and agents against any claims, losses, liabilities, and reasonable costs arising from your use of the Service, Your Content, your breach of these Terms, or your breach of any law or third-party rights.

12. Suspension and termination

We may suspend or terminate your access to the Service, in whole or in part, with or without notice, where:

  • You breach these Terms
  • We are required to by law
  • It is necessary to protect the Service, other users, or us

You may stop using the Service and close your account at any time. Sections that by their nature should survive termination (including content responsibility, indemnity, and limitation of liability) will survive.

13. Changes to these Terms

We may update these Terms from time to time. When we make material changes, we will update the "Last updated" date and, where appropriate, notify you. Your continued use of the Service after changes take effect constitutes acceptance of the updated Terms. If you do not agree to a change, your remedy is to stop using the Service and close your account.

14. Governing law and jurisdiction

These Terms are governed by the laws of England and Wales. The courts of England and Wales have exclusive jurisdiction over any dispute arising out of or relating to these Terms or the Service, except that, if you are a consumer resident elsewhere, you may benefit from any mandatory protections of your local law.

15. General

  • If any provision of these Terms is found unenforceable, the remaining provisions continue in effect.
  • Our failure to enforce any right is not a waiver of that right.
  • You may not assign or transfer your rights under these Terms without our consent. We may assign ours in connection with a merger, acquisition, or sale of assets.
  • These Terms, together with our Privacy Policy, are the entire agreement between you and us regarding the Service.
