Glossary

Every word this section uses that does not mean what you would guess.

People and companies

Word	What it means
Person	The lead. Somebody you may write to, at an address or on a handle. They may work at a company, run one, or have none at all.
Company	Context about a person: the organisation they work for or run. Identified by its website domain, not by its name, so two spellings of one name are one company. A company may hold several people.
Individual	A person written to at their own address rather than at a business’s: anybody in an Individuals campaign, and anybody at a personal mailbox such as Gmail in any campaign. The word decides whether the consent rule applies to them.
Handle	Somebody’s name on a platform, such as `@harrowfieldmakes`. Every spelling of one reduces to the same word, so the bare word, the @ form and the profile link are one handle. In an Individuals campaign it identifies a person the way a domain identifies a company.
Channel	A platform a person is reached on: Instagram, TikTok, YouTube, LinkedIn or X. A person holds at most one handle per channel, and the same word on two channels is not by itself the same person.
Consent basis	Why this person may be sent to automatically: a recorded consent, a soft opt-in, or none. Only an import column naming where consent came from writes one.
Soft opt-in	An existing customer relationship, which counts in place of consent. Reserved for the reply path; nothing writes it today.
No consent	The reason a letter to an individual is held when no basis has been recorded. It lifts when a consent is recorded, and never by itself.
Verified	The address was checked and a mail server answered for it. Only verified people are written to.
Catch-all	The company’s mail server accepts every address, so nothing can be proven either way. Not the same as verified, and not the same as invalid.
Invalid	The address bounced. The person stays on the list and stops being written to.
Waterfall	The ordered search for an address, cheapest step first: syntax and mail servers, then likely patterns, then a direct probe, and only then a paid provider, which asks for approval before the money goes.
Schedulable	This person could be sent to right now: verified, not suppressed, with a healthy domain and a switched-on address available. Somebody can be verified and not schedulable.
Suppressed	This address must never be written to again, anywhere, on any campaign. Permanent, and not undone by importing them again.

Sending

Word	What it means
Campaign	One piece of outbound work: a list, a sequence, and everything that came back. It is for Businesses or for Individuals, and that is fixed when it is created.
Businesses campaign	The default kind. Every row it takes names a company, and a handle is recorded but never read as an identity. Every campaign made before the choice existed is one.
Individuals campaign	A campaign whose rows are people first. A name and any one of a company, an address or a handle admits a row, and everybody in it is an individual for the consent rule.
Sequence	The letters and the gaps between them. Gaps are counted in working days.
Step	One letter in the sequence.
Identity	One of your sending addresses.
Domain	The part after the @ in your sending address. Health belongs to the domain, which is why the warden pauses domains rather than mailboxes.
Fleet	A batch of mailboxes bought together, named by you.
Warm-up	The ramp a new mailbox goes through before it may carry campaign mail. Usually fourteen days.
Heat	How much a mailbox has sent recently against its cap. At the cap it sends no more that day.
Placement	The proportion of test mail landing in an inbox rather than in spam. The earliest warning you get.
Sequencer	The service that puts letters on the wire and reports what happened. A campaign names one.
Send window	The hours a campaign may send, in its own timezone.
Review policy	How many letters a person reads before the campaign may send the rest unread.
Reviewer ladder	Who may clear a letter to send, and who it falls to next when they do not. It is what the send approval asks.
Held	A letter that exists and may not go, because a condition is not true. It always names the condition.

Replies

Word	What it means
Touch	One recorded contact, in either direction, on any channel. The row every screen counts.
Direct message	A message on somebody’s own platform, in or out. Neutron never sends one, and never sees one; you log it by hand and it becomes a touch like any other.
Label	How a reply was read. One of seven: positive, meeting, more info, referred, not now, out of office, unsubscribe.
To triage	Nothing has read this message. Not a label, but the absence of one.
The deterministic pass	The reading that costs nothing and is not a guess: headers, and the sender’s own words.
The classifier	The model pass, for what the deterministic pass could not read. It must name the sentence it read and say how sure it is.
Evidence	The sentence a reading was made from, shown so you can disagree with an argument rather than with a verdict.
Own words	The top of a reply, above the letter it quotes. Read whole, every reply would match our own unsubscribe footer.
Inbox	Where replies and the answers drafted for them wait. An agent may write an answer here and may never send it.
Correction	A person disagreeing with a reading. It changes the label, runs the new label’s effects, and is kept as a pair with what the machine said.
Hand-off	Taking a conversation out of the automatic flow and giving it to a person.

Money

Word	What it means
Deal	An opportunity with a company. Opens by itself on a positive reply. One per company per campaign.
Commission	What a deal is worth to you, worked out from its value and its rate.
Configured price	A price you typed in, because the vendor does not publish one.
From the vendor	A price read from the vendor’s own interface, which moves when theirs does.
A floor	The Costs figure. The least this can cost, not the most, because it counts only what the engine can see.

The machinery

Word	What it means
The warden	The daily check on domains and mailboxes. It pauses a domain on evidence and says why.
Incident	The record opened when the warden pauses something, so the pause has a reason attached to it.
The spine	The fixed, forward-only set of states a person moves through.
Seam	The one small piece of code that translates between the engine and one outside service. Swapping a vendor changes a seam and nothing else.
Claim	A factual statement about your business that a letter may make, with a source and a review date. Approved per language.
