One address, and a person on the other end.

Expect a reply within a day or two. If something is broken and you are a customer, say so in the subject line and it goes to the top.

What to write about

You want to try it

Ask for an invitation instead — it takes less time and the one question it asks, roughly how many client sites you look after, is the thing that tells us whether this is built for you. Sign-up is invitation-only while we are working with a small number of agencies.

You think we have got something wrong

Especially welcome. An alert you did not believe, a report that did not match what you saw, a claim on this website that is not true — all of those are bugs and all of them get fixed.

You found a security problem

Write to the same address with enough detail to reproduce it. What happens next is set out on the security page.

You want your data deleted

Say so and it happens, within thirty days and usually much sooner. You do not need to give a reason and we will not ask for one. The privacy page covers what else you can ask for.

You look after client sites and want to tell us how you really work

This is the most useful email we can receive, and it is worth more to us than a sale. Twenty minutes about how you currently find out a client site has broken. We are not going to pitch you.

Placeholder. A postal address has not been set for this site. Fill it in at tools/build_site.py — a privacy policy and terms both need one before the domain goes public.
