FAQ

How often do you send it?

There is no fixed schedule. Roughly twice a month, whenever we have measured data or lessons from a project worth sharing.

Can I unsubscribe?

Yes, at any time. Just reply to any email with the word 解除 (kaijo — “unsubscribe”) and we stop right away.

Will you send me sales emails?

No. The newsletter is an extension of the blog. We never reach out to sell — we only reply when a reader contacts us first.
