Mailbox providers watch how recipients react to your mail. Messages that arrive while people are at their desks get opened, read, and replied to — engagement signals that build your sender reputation. Messages that arrive overnight sit at the bottom of a morning pile, get deleted in bulk, or get reported, and every one of those reactions teaches the spam filters something about you. A send window is the simplest way to stack that behavior in your favor: it doesn't change what you send, only when. It's also plain manners — the kind of detail a recipient never consciously notices but a filter always does.
In Brohns, the send window sits in your email guardrails alongside the daily send limit and the do-not-contact list, and it's enforced on the server rather than trusted to the interface. It works together with approval, not instead of it: approving a drafted message is still what decides whether it goes out — the window just refuses to let that happen at the wrong hour. If you approve outside the range you've set, the send is blocked with a plain explanation asking you to approve again within the window; nothing slips out at midnight, and nothing sits in a hidden queue waiting to surprise you later. You can read and edit drafts whenever suits you — only the send action itself has to happen inside the hours you chose. And because Brohns sends through your own Resend or Gmail account rather than a shared platform domain, the reputation the window protects is genuinely yours.
A sensible window for B2B outreach is plain business hours. The setting is a simple daily start and end time, so pick the stretch when your prospects are most likely at their desks — and if your Finder agent sources local businesses in your own area, your working hours and theirs largely overlap, which makes the call easy. Pair the window with a modest daily limit so volume ramps gradually instead of spiking. Note that the window doesn't loosen as trust grows: even if you later move an ecosystem up the autonomy ladder and let routine sends run without per-message sign-off, they still happen inside the window, under the daily cap, and on the audit log. Guardrails are the constant; how granular your approvals are is what changes.
