Welcome to Mail Tool Hub. By accessing or using our website (located at mailtoolskit.com) and the suite of email verification and outreach optimization tools we provide, you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use our website or services.

1. Acceptance of Terms

By accessing Mail Tool Hub, you confirm that you have read, understood, and agreed to be bound by these Terms of Service, as well as our Privacy Policy. These terms apply to all visitors, users, developers, and others who access or use the website.

2. Description of Services

Mail Tool Hub provides a collection of free, browser-based utilities designed to check email list validity, verify SPF/DNS records, run SMTP handshake simulations, analyze spam keywords, and optimize email outbound outreach campaigns.

Unless explicitly stated otherwise, the majority of our tools execute locally within your web browser (client-side processing) using Javascript. This ensures high speed and private data handling, as your lists and email drafts are not stored on our servers.

3. Permitted and Acceptable Use

You agree to use Mail Tool Hub only for lawful purposes and in accordance with these Terms. You specifically agree NOT to:

Use the services to facilitate bulk unsolicited commercial email (spam) in violation of the CAN-SPAM Act, GDPR, or other global anti-spam regulations.
Use any automated scripts, bots, scrapers, or tools to harvest data, crawl directory structures, or systematically query our APIs without prior authorization.
Attempt to bypass rate limits or compromise the security, infrastructure, and availability of our hosting servers.
Use our email lookup, corporate finder, or verification tools to harass, stalk, or send threatening messages to third parties.

4. Privacy & Data Handling

Your data privacy is our highest priority. Because our tools operate primarily client-side inside your browser:

The emails you verify, lists you clean, and drafts you scan are processed in-memory and are never written to database storage or logged by Mail Tool Hub.
Any server-side lookup (such as SPF DNS resolving or SMTP handshakes) is processed transiently and immediately discarded.

5. Intellectual Property Rights

The website structure, custom CSS frameworks, SVG iconography, scripts, and branding elements (excluding third-party open-source libraries) are the exclusive property of Mail Tool Hub and are protected by copyright and intellectual property laws. You may not copy, modify, distribute, or reverse-engineer any portion of the site without written consent.

6. Disclaimer of Warranties

Mail Tool Hub is provided on an "AS IS" and "AS AVAILABLE" basis. We make no representations or warranties of any kind, express or implied, as to the operation of the services or the accuracy of the verification results.

While our heuristics are updated regularly, email deliverability variables (such as inbox filter changes, temporary SMTP timeouts, and dynamic domain blacklists) mean that we cannot guarantee 100% accuracy of validation status flags.

7. Limitation of Liability

In no event shall Mail Tool Hub, its creators, or partners be liable for any direct, indirect, incidental, special, or consequential damages (including, but not limited to, loss of outreach responses, dropped marketing campaigns, domain suspension by ESPs, or data loss) arising out of the use or inability to use our tools.

8. Changes to Terms

We reserve the right, at our sole discretion, to modify or replace these Terms of Service at any time. We will indicate the date of the latest update at the top of this page. Your continued use of the website following any changes constitutes acceptance of the new terms.

9. Contact Us

If you have any questions or feedback regarding these Terms of Service, please reach out to us via our project repository or feedback forms.
