Privacy policy
Effective 15 November 2026. This policy covers the beta of mailwarmups.com.
Who we are
mailwarmups.com is run by the operator of mailwarmups.com (Zelus Labs). In this policy, "we" means that operator.
21601 Vanowen St, Canoga Park, CA 91303What we collect
- Your email address, which you sign in with.
- The address of each mailbox you connect, its provider, and the settings you give it: the display name, role, company description, timezone, working hours and daily number of letters.
- The app password of each mailbox you connect. The hub keeps it sealed, as the security page explains.
- The letters the network writes on your behalf, the replies to them, and where each one lands.
- Basic server logs, which include IP addresses.
- Page views, clicks and scrolling on this site, through the hub's page-view tracker.
Why we collect it
To run the service: to sign you in, to send and receive the network's letters for your mailbox, and to show you where they land.
To keep it safe: to limit sign-in attempts, to stop abuse of the network, and to find and fix problems.
Where it is processed
On the operator's hub, which runs on Render in the United States, and in Firestore, the database the hub uses. Sign-in codes are sent by email through SendGrid, the hub's email provider. The network's letters travel through your own mail provider, as any email you send does.
Who sees it
The operator sees it, to run the service. The other mailboxes in the network see the letters your mailbox sends them, with your mailbox address and display name, as with any email.
The companies named above process it for us, only to run the service.
How long we keep it
- A sign-in code works for 10 minutes. We store only a one-way hash of it.
- Letters and where they landed: 14 days in detail, then only daily counts.
- Your account and its mailboxes: until you delete them.
Your choices
- Pause a mailbox, or disconnect it, from your dashboard at any time. A disconnected mailbox sends nothing, and its app password is erased.
- Remove a mailbox once it is disconnected.
- Revoke the app password at your mail provider at any time.
- To delete your account, email hello@mailwarmups.com from the address you sign in with.
No selling, no advertising
We do not sell your data. We do not share it for advertising, and this site carries no third-party advertising.
Cookies and browser storage
- One session cookie, which keeps you signed in for up to 30 days.
- One short flash cookie, which carries a one-line notice to the next page and lasts at most 2 minutes.
- No tracking cookies.
The hub's own page-view tracker records page views, clicks and scrolling on this site, and reports them only to the operator's hub. It keeps a random visitor id in your browser's local storage, not in a cookie.
Changes to this policy
If we change this policy, we post the new version on this page with a new effective date.
