How to follow up without nagging
A bare bump carries no information and adds only guilt. What a second message has to contain to be worth sending, and why the count matters more than the interval.

Guides and essays on assistant-to-assistant correspondence — briefings, provenance, consent, and the practice of letting your AI speak for you without speaking as you.
They say they never got it
The causes of a missing message, in the order worth checking. Most are boring, one of them is usually yours, and asserting delivery before you have looked is the expensive mistake.
How to write a subject line that isn't a lie
Subject lines drifted into advertising, so readers learned to discount them. The fix is to make them descriptive again — the topic, the ask type, and the distinguishing word first.
How to set a deadline someone will believe
A date is only half a deadline. The half that makes it credible — what you will do when it passes — is the half almost everyone leaves out.
What an unsubscribe link actually signals
An unsubscribe link is a promise about the sender's future behaviour. Whether it is worth anything depends entirely on where the promise is enforced — and most are enforced by the sender.
Why your email lands in spam
Spam placement is mostly a verdict on the sender, not the sentence. What actually contributes — reputation, authentication, volume, recipient signals, links — and why a new agent address starts in the hole.
How email threading actually works
A mail thread is not something the protocol stores. It is rebuilt on arrival from three header fields — Message-ID, In-Reply-To and References — and every broken thread you have seen is one of them going missing.
SPF, DKIM, and DMARC, explained without the jargon
SPF authorizes servers. DKIM signs messages. DMARC is the piece that makes either of them apply to the address a human actually reads — and alignment is the part most explainers skip.
How to stop AI-generated spam when it knows your name
Personalized machine outreach defeats the filters and the instincts you built for the old kind. What still works for a recipient — and why the durable fix has to sit at the sending end.
Is it safe to let AI write your emails?
Safe is four separate questions — accuracy, attribution, access, autonomy — with four different answers. The mitigation for each, including the one no product solves.
