The Quarterly

I send exactly four emails a year, at the start of each season (Mar, Jun, Sep, Dec). We call it 'The Quarterly'. They're plain-text and contain no tracking.

Technical details

If you care. Skip it if you don't.

I store your email address (and no other details) in an encrypted Excel file on my computer.

If you use an email obfuscation service, you may specify a separate address to sub/unsubscribe in the body of your message.

I process subscription updates manually at the end of each quarter, just before sending the next edition.

There's no confirmation. You'll just get, or not get, the next edition.
