Terms of service

Last updated: September 25, 2026

The short version

Mailster is a free website with email tools and written guides. Use it, share it, learn from it. Don't abuse it, don't pretend you built it, and understand that everything here is provided without a guarantee that it will fit your exact situation.

Using Mailster

By browsing this website you agree to these terms. If you do not agree with them, please stop using the site.

You may use Mailster for personal or commercial work. You may not:

attempt to break, overload or gain unauthorised access to the site or its servers;
scrape or republish the site's written guides as your own content;
use the tools to send unsolicited bulk email or to spoof a domain you do not control;
resell the tools as a paid product without written permission.

Tools are provided as-is

Every tool on Mailster is provided free of charge, on an "as is" and "as available" basis, without warranties of any kind. Tools that look up DNS records depend on third-party services and may return incomplete or outdated results. Always verify important settings at your domain registrar or mail host before relying on them.

No professional advice

The guides describe general practices around email marketing and deliverability. They are not legal, financial or compliance advice, and they cannot account for your industry, list or jurisdiction. For legal questions — including consent, unsubscribe requirements and data protection — speak to a qualified professional.

Intellectual property

The Mailster name, design and written content belong to the site owner. You are welcome to link to any page and to quote short excerpts with attribution. Republishing whole guides without permission is not allowed. Output you generate with a tool — a signature, a mailto link, a countdown snippet — is yours to use freely.

Third-party links and services

Some pages link to other websites or rely on third-party services such as public DNS resolvers. We do not control those services and are not responsible for their content, availability or privacy practices.

Limitation of liability

To the fullest extent allowed by law, Mailster is not liable for any indirect or consequential loss arising from your use of the site — including lost revenue, lost subscribers, or email that lands in a spam folder. Your only remedy if you are unhappy with the site is to stop using it.

Changes to these terms

These terms may be updated as the site grows. The date at the top of this page always reflects the current version, and continued use of Mailster after a change means you accept the updated terms.
