Terms of service
Last updated 27 August 2026
1. What the service is
SenderCheck is a diagnostic tool. It reads publicly published DNS records for a domain you specify and reports on their configuration. It is not an email sending service, a mail host, a customer relationship system, or a deliverability consultancy.
2. No guarantee of delivery
The service reports on published configuration only. It does not and cannot guarantee that any message will be delivered to any recipient or placed in any particular folder. Delivery depends on sending reputation, message content, recipient behaviour and each receiving provider’s own filtering, none of which are observable from DNS. Nothing in the service or its output constitutes a promise about delivery outcomes.
3. Accounts
You are responsible for the security of your account and for all activity under it. You must provide an email address you control, and you must be legally capable of entering into this agreement.
4. Acceptable use
Manual checks operate on public DNS and may be run for any domain. Continuous monitoring requires you to demonstrate control of the domain by publishing a verification record. You must not use the service to attempt unauthorised access to any system, to circumvent rate limits, or in any way that degrades it for others. The Acceptable Use Policy forms part of these terms.
5. Subscriptions and billing
Paid plans are billed in advance, monthly or annually, through Stripe. Prices are shown before purchase. Subscriptions renew automatically until cancelled. You may cancel at any time from your account without contacting us; cancellation takes effect at the end of the period you have already paid for, and no refund is issued for the remainder of that period unless required by law.
If a payment fails, your plan continues during a grace period while the payment provider retries. If payment is not resolved, monitoring is suspended and the account reverts to the free tier. Your configuration is retained for the period published in the Privacy Policy so that you can reactivate.
6. Plan limits
Each plan carries stated limits on monitored domains, check frequency and manual checks per day. These limits are enforced technically. We may apply reasonable rate limiting to protect the service, including on the free tier.
7. Availability
The service is provided on a commercially reasonable efforts basis, with no guaranteed uptime. Scheduled checks depend on third-party DNS infrastructure outside our control and may occasionally fail to complete; where that happens we report the result as incomplete rather than presenting a partial answer as a whole one.
8. Your data
Handling of personal data is described in the Privacy Policy. You may delete your account at any time from your account settings, which removes your personal data and monitoring history on the schedule described there.
9. Intellectual property
The service, its diagnostic content and its interface remain our property. Reports generated about domains you control are yours to use freely.
10. Liability
The service is provided “as is”. To the maximum extent permitted by law we exclude implied warranties, and our aggregate liability is limited to the amount you paid in the twelve months preceding the claim. We are not liable for indirect or consequential loss, including lost business or undelivered email. Nothing here limits liability that cannot lawfully be limited.
11. Changes
We may update these terms. Material changes will be notified by email to account holders at least 14 days before they take effect. Continued use after that constitutes acceptance.
