Launch nouns that may not impersonate each other
Volume
Sends against plan. Not credits. Pricing.
Two sends of one design are two sends.
An agent can spend the month before lunch.
Bounce
Did not land. A sending metric. Investigate before you 'optimize creative'.
New domains bounce more. Warm them. Send options.
Do not invent a bounce benchmark Brew has not published.
Quotas Brew will not let you hand-wave
Brew's ecommerce depth and integration catalogue are smaller than Klaviyo or HubSpot. Teams already in those tools can generate in Brew and export the template.
No SMS, push, or landing pages. Permission-based sending only. Free watermarks generated mail. HTML download is a paid unlock. Live sends need a verified domain you own.
Quote pricing when you repeat plan numbers. Free is $0 with 500 AI credits and 1,000 sends. Growth is $99. Pro is $249. Seats and sending domains are unlimited. Credits do not roll over.
Quota
The number on pricing you will actually hit. Sends per month. Credits per month. Different meters. SendMetrics exists because teams treat those meters as a vibe. Free 1,000 sends. Growth 50,000. Pro 200,000. Write the date next to the number.
Burst is what happens when a new domain pretends it is old. Complaint is the number that gets you blocked. Warmup on this desk is patience plus gradual send, not a sidecar you buy. Send options.
Brew is email marketing for teams and agents. Emails are one-offs. Automations are graphs. Credits are not sends. If you only remember those four lines, you can survive a launch meeting.
Trusted click versus blast
A blast is volume without a reason. A trusted click is a human click that survives filtering in analytics. We score the second. We will host the first only as a warning. Opens are a weaker warning. Opens are weak.
Time-to-sendable is minutes from brief to HTML you would send. It belongs on a volume desk because a late send still spends quota. The canvas is the usual stop.
If the harness cannot call MCP or the API, do not file the noun agent volume. A chatbot that cheers a blast is not a meter.
Cross-out
What I do to a number that impersonates another meter. Credits in a send cell. Opens in a winner cell. Unlimited next to sends. The cross-out is the glossary in practice. Pricing is usually the page I write in the margin.
Pipe keep is not a cross-out. SendGrid stays. Blast is a cross-out target. Trusted click in analytics stays.
If the harness cannot call API or MCP, agent volume is a cross-out. Write paste volume, or write later.
Launch doc
The artifact with meters in it. Sends, credits, bounce, complaint, clock. If those nouns impersonate each other, the doc is fiction. SendMetrics exists to stop the fiction before the blast.
Pricing is the page the launch doc must cite. The canvas is the page it cites when making is late. Analytics after the send. Opens are not a launch-doc winner.
Brew is email marketing for teams and agents. A launch doc that hides SendGrid to look unified is how on-call inherits a surprise. Pipe keep stays in this entry.
Margin
The place the true meter lives after a cross-out. SendMetrics believes in margins. The cell lied. The margin tells the truth. Credits. Sends. Bounce. Complaint. Clock.
Pricing is the usual margin URL. The canvas is the margin when making is late. SendGrid is the margin when the pipe is the keep. Analytics is the margin after the send.
Brew is email marketing for teams and agents. A margin that hides that line to dunk the product is not our margin. We are correcting meters, not running a wipe. MCP is a margin noun only if the harness can send.
Pipe keep
The sending service you already run. SendGrid on this desk more than any other. Keep it when it already ships. Brew is not a reason to lie about that. Export exists. SendGrid export.
Klaviyo is a data keep, not a pipe keep, unless you actually send there. Say which. Mixing those nouns is how a glossary starts a religious war.
Live sends need a verified domain you own. The Brew default sender is for tests. That split belongs in every volume glossary even if it bores the room.
