Terms of Service.

Last updated: July 2026

These Terms of Service govern your use of MailViewed. By accessing or using the website, browser extension, or service, you agree to these terms.

Using MailViewed

You may use MailViewed to track the delivery and reading of messages you are authorised to send. Don't use it for spam, harassment, stalking, or to track people in ways that break the law in your jurisdiction.

Your responsibility for recipient data

When you track an email, MailViewed records open and click activity about your recipients on your behalf. For that data, you act as the data controller and MailViewed acts as your processor: we store and process it only on your instructions and as described in our Privacy Policy. You are responsible for using tracking lawfully under the privacy laws that apply to you and your recipients (for example the GDPR if you email people in the EU), and for honouring any objection a recipient raises with you directly.

Your account

You're responsible for activity under your account. We may suspend accounts that abuse the service or put others at risk.

Sending email through MailViewed

If you connect your Gmail account, you authorise MailViewed to send emails on your behalf (using Google's gmail.send permission) only for messages you compose in the app. You are responsible for the content of those emails and for complying with anti-spam laws and Google's policies. You can disconnect Gmail at any time, in the app or from your Google account. Our handling of Google user data is described in our Privacy Policy.

Availability

We work hard to keep MailViewed running, but it's provided "as is" without warranties. We may change or discontinue features, and we aren't liable for indirect or consequential damages.

Plans, billing and refunds

The core service is free. If you purchase a paid plan, billing is handled by our merchant of record, which processes payment and issues your invoice. You can cancel anytime and keep paid features until the end of the billing period. Refunds are described in our Refund Policy. If we change pricing, we'll give notice, and early founder accounts keep their free tier as described on the pricing page.
