Explicit opt-in
Subscribers enter their own email address and explicitly consent through the newsletter form. Contact-form users are not automatically subscribed.
No purchased or scraped lists
We do not use purchased, rented, scraped, or third-party marketing lists.
Frequency
We generally aim for no more than 1–3 messages in a week when there is a relevant tool, note, update, or announcement.
Unsubscribe
Every marketing message should provide a clear unsubscribe method. The public unsubscribe page is also available at any time, and opted-out addresses are suppressed from future marketing sends.
List hygiene
Invalid addresses, hard bounces, complaint addresses, and addresses that should no longer receive marketing email are removed or suppressed.
Authentication and feedback
Regular production sending is intended to use an authenticated domain, bounce/complaint feedback processing, and standard List-Unsubscribe or one-click unsubscribe support where available.
