About Mailer

Twice a month, one issue about writing, designing, and sending a newsletter people finish.

Sending since April 16, 2026

What this is

Mailer is a fortnightly letter about the unglamorous parts of running a newsletter: the paragraph you cut, the template that renders badly in Outlook, the deliverability problem that was really a consent problem, and the readers who quietly stopped opening.

Every issue is one argument, long enough to be useful and short enough to finish on a commute. No sponsor blocks, no link dumps, no sequences designed to warm you up.

What arrives

  • Every other Thursday, sent first thing in the morning.
  • Occasional interviews with people who have been publishing for years.
  • Nothing else. No launch emails, no webinars, no partner offers.

Who writes it

Mara ChenEditorEdits Mailer and writes most of the craft pieces. Ran a books newsletter for six years before this one and still thinks the hardest part of any issue is the last paragraph.
