Newsletter
Nearly there — check your inbox and tap the link in the email to confirm. Nothing is sent until you do.
Confirmed — you're on the list. At most one email every two weeks, and only when something fits what you use.
That confirmation link did not match anything. Sign up again below and a fresh one will come.
Tick the box beside the form — that is the sign-up.
That email did not look right — go back and try again.
Sign-up is briefly unavailable, or you have tried a few times in the last hour. Please try again in a little while.
You're unsubscribed — no more emails from us, on any of the three sites. Changed your mind? Sign up again any time; a confirmation email brings you back.
That unsubscribe link did not match anything. Use the link in your newest email, or the switch on your account page.
The list is closed — nothing to confirm, nothing goes out.
There's no email list running right now — nothing to sign up for, nothing goes out. Already on it from before? The unsubscribe link in any old email still takes you off, one click.
At most one email every two weeks, with the calculators and references that fit what you use — here and on fieldcalc.net and sparkytools.net. The form at the foot of this page is the whole sign-up: tick the box, then confirm from your inbox.
What lands in your inbox
- Calculators and references related to the ones you have opened or emailed yourself from — on bentright and on fieldcalc.net and sparkytools.net.
- A new calculator or reference in the groups you use, with the bend it solves and the marks it gives.
- A correction, if a figure on the site turns out to be wrong. Those go out on their own.
At most one every two weeks, and nothing at all when there is nothing that fits.
What it is not
- Not an account. Nothing on this site needs one, and none of the calculators change.
- Not shared or sold. It is one list across the three sites, and one unsubscribe takes you off all of it.
- Not hard to leave: one click in any email, no questions.
What is stored, and why, is on privacy.
