Notes on deliverability, from the trenches.

Practical guides on SPF, DKIM, DMARC and blacklists — written from real incidents we monitor, not marketing calendars.

Nothing published yet. The first notes are being written.

One email a month, only when we have something to say.

Deliverability notes + incident write-ups. No product spam — we'd be embarrassed.
