Cookie Notice

Four cookies, all of them necessary, none of them advertising. Here is each one and what it does.

Effective 25 July 2026.

Why there is no cookie banner

Under the ePrivacy rules, consent is needed for cookies that are not strictly necessary to provide a service you asked for. Advertising and analytics cookies need consent. Necessary ones do not.

Every cookie we set is necessary: signing you in, completing a sign-in safely, remembering your workspace, and crediting an affiliate whose link you deliberately followed. We set no advertising cookies and no third-party analytics. So there is nothing to ask you about, and we would rather not interrupt you to say so.

They are all first-party cookies set by mcpmailer.com. None of them are readable by another site, and none are shared with advertisers.

CookieWhat it doesLasts
better-auth.session_tokenKeeps you signed in. Without it every page would ask for your password again.Until the session expires or you sign out
better-auth.state, better-auth.pkceShort-lived values that complete a sign-in or an OAuth authorisation safely, and stop someone else finishing it for you.Minutes, deleted once the sign-in completes
mm_wsRemembers which workspace you were last working in, so the dashboard opens there.1 year
mm_refRecords which affiliate link you arrived on, so the affiliate is credited if you sign up later. Set only if you arrive on a link containing a referral code.90 days

Open-tracking pixels are a separate thing

MCPmailer can add an invisible image to an outgoing message to count whether it was opened. That is a tracking pixel in someone's email, not a cookie on this website, and it sets nothing in your browser.

It is off by default and is switched on per message by the customer sending it. If you receive tracked mail, blocking remote images in your mail client stops it, and the sender, not us, decides whether to use it. See the Privacy Policy for what is recorded.

Controlling cookies

You can delete or block cookies in your browser settings. Blocking ours will sign you out and stop the dashboard working, because the sign-in itself depends on them. Blocking only the referral cookie is harmless: an affiliate simply will not be credited.
