Questions and answers.

We're not charging for it. Your blog runs on your own Cloudflare account, on its free plan, so it costs us next to nothing. That plan covers around 3 million page views a month, so only a very busy blog would ever need Cloudflare's paid plan. There are no adverts and nothing is sold.

No. If you can send an email, you can run this blog. You'll need a free Cloudflare account to install it, and the installer does the rest for you in about 2 minutes.

You link your Cloudflare account, and Cloudflare asks you to allow it. The installer then does five things in your account, and nothing else:

• Creates a small database for your posts and settings.
• Creates a storage space for your pictures.
• Installs your blog as a Worker called blog-by-email, with a daily tidy up.
• Switches on your blog's address: a free workers.dev address or your own domain.
• Sets up your posting address, so your emails reach your blog.

If you switch on email subscriptions, it also sets up sending for your blog's domain and adds the email records Cloudflare asks for (bounce, SPF and DKIM). It never changes your existing email.

The link to your Cloudflare account lasts 60 minutes and is cut off when you sign out. We don't keep it, and we don't touch your other websites, email or settings. Running the installer again updates your blog and keeps every post.

Yes, if your domain is on the same Cloudflare account. Use your main domain, a subdomain such as blog.yourname.co.uk, or a folder of your existing website. You can move to it later and keep every post.

Only you. Your blog only accepts email from your own address, and only if it passes the same security checks mail providers use. You can add another address of yours in your settings.

Every post sends you a reply with its link. Reply with Publish, Hide or Delete, or send the corrected post back to replace it. Deleted posts wait in the bin for 30 days.

Yes. Any email app works, on any phone, tablet or computer. Save your posting address in your contacts as "My blog" and it's always to hand.

Yes. Sign in to My posts with a link sent to your email, then press Edit on any post. You can also publish drafts and hide or delete posts there.

Yes. Add another address of yours in your settings and posts from it are taken too, as long as they pass the same security checks.

Yes. Any email that passes the usual security checks works, from any provider.

Yes. Switch on email subscriptions and readers see a Get new posts by email box on your blog. They confirm their address, then get each new post by email, with an unsubscribe link in every one. Open Subscribers in your blog's settings and press Check and switch on. The installer checks your account, sets up sending for your domain and sends you a test email. See the step by step guide.

Cloudflare only lets accounts on its Workers Paid plan send email to anyone, and the emails go from your own account, not ours. That's why Blog by Email stays free. The plan is $5 a month, paid to Cloudflare, and includes 3,000 emails a month, such as 300 subscribers and 10 posts. After that it's $0.35 per 1,000 emails. Your blog also needs to be on your own domain, as email has to come from a domain you own.

Only in your own Cloudflare account. We never see it. You can download it as a spreadsheet any time. If you turn subscriptions off or stop paying Cloudflare, the sign up box is hidden and nothing is sent, and your list is kept for when you turn it back on.

Your blog and posts live in your own Cloudflare account, not on ours. Your blog has no cookies, no trackers and no adverts. All we keep is your posting address and your blog's web address, so we know where to pass each email. Your posts and pictures go straight to your blog.

Sign up for updates and we'll email you when there's a new version or feature. Your blog's settings page also tells you when there's a new version. To update, link your Cloudflare account again and press Update my blog. Every post and setting stays as it is.

Email hello@blogby.email and we'll help. Tell us your blog's web address and what happened, and send a screenshot if you can.
