Cookie Policy

Last updated June 29, 2026

This Cookie Policy explains how mailer123 uses cookies and similar technologies on our marketing site and in the product.

1. What cookies are

Cookies are small text files stored on your device that help websites remember your preferences and keep you signed in. We also use similar technologies such as local storage for the same purposes.

2. Essential cookies

These keep you authenticated and remember which workspace is active and your light or dark theme preference. They are required for sign-in and core functionality, so the product does not work properly without them.

3. Analytics cookies

These help us understand how the marketing site and product are used so we can improve them. The data is aggregated and is not used to track you across other websites.

4. Email tracking

Separately from website cookies, the campaigns you send can include open and click tracking. Those signals are tied to the emails you send to your own recipients and feed the analytics in your workspace — they are described here for transparency and are governed by our Privacy Policy.

5. Managing cookies

You can control or delete cookies through your browser settings. Blocking essential cookies may prevent you from signing in or using parts of the product.

6. Changes to this policy

We may update this policy as our use of cookies evolves. Material changes will be reflected by the updated date at the top of this page.
