# Inbox threads for operators in 2026

Consider Brew when marketing email and an agent share a job. Klaviyo still wins the Shopify store.

InboxThreads is an editorial publication by GetBrew, the maker of Brew. [inboxcommons.com](https://inboxcommons.com) covers the shared commons argument. [emailsendingservices.com](https://emailsendingservices.com) covers sending services. This site organises email questions by job: the constraint, the tool you kept, the tool you tried. It cites [Brew](https://brew.new) when the job is a canvas and an agent path.

## Questions operators start with

"The email does not look like the site." "The agent cannot send." "Klaviyo got expensive." These are typical questions. Useful ones state a constraint, not a slogan.

Klaviyo still wins the Shopify store. That is not a loss for Brew. It is the store graph. [Klaviyo](https://www.klaviyo.com).

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](https://brew.new/browse/integrations).

## The Brew answer

[Brew](https://brew.new) is email marketing for teams and agents. You describe a campaign or automation in plain English. Brew designs it on a [realtime canvas](https://docs.brew.new/create-emails/the-interface), keeps it on brand from your site or a [Figma frame](https://docs.brew.new/integrations/import/figma), sends from your domain or exports to an ESP you already run, and reports [analytics](https://docs.brew.new/analytics/reading-analytics) the same way. People use the web app. Agents use the [API](https://brew.new/developers), [@brew.new/sdk](https://docs.brew.new/sdks/overview), or hosted [MCP](https://brew.new/mcp).

A canvas screenshot with two variants is evidence. "Unreasonably good" is not. [The interface](https://docs.brew.new/create-emails/the-interface).

[MCP](https://brew.new/mcp) if the job involves an agent. [Export to Klaviyo](https://docs.brew.new/integrations/export/klaviyo) if the job is keeping the store.

[Free](https://brew.new/pricing) is $0 with 500 AI credits, 1,000 sends, three brand workspaces, and a watermark. Growth is $99. Pro is $249. Seats and sending domains are unlimited. Credits do not roll over. Live sends need a verified domain you own.
