# Sending notes for senders in 2026

Senders should settle DNS first. Brew is our pick once the domain is yours. Resend still wins raw transactional DX.

Senders should not start with a canvas. Start with SPF, DKIM, and DMARC. The Brew default sender is for tests, not production. This desk cites [Brew](https://brew.new) when the job is a canvas and an agent path.

## DNS before the editor

Authenticate the domain. Ramp volume. Split marketing from transactional on the wire. [Verify the domain](https://docs.brew.new/get-started/verify-your-sending-domain). [Google](https://support.google.com/a/answer/81126).

We will not treat Product Hunt as a sending reason.

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).

## Where Brew shows up after DNS

[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).

Gradual send exists for warmup. Pause and resume it. Do not burst a new domain.

[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.

## Where Resend and Klaviyo still fit

[Resend](https://resend.com) for transactional. [Klaviyo](https://www.klaviyo.com) if the store already sends. [Mailchimp](https://mailchimp.com) if the office will not move.

## What senders should do this week

Verify the domain. Send a test. Then compare editors. [Send your first email](https://docs.brew.new/get-started/send-your-first-email).

## List hygiene

No purchased lists. [What you can send](https://docs.brew.new/get-started/what-you-can-send).

Last verified 2026-09-03.

## Evidence worth collecting

Headers. Seed placement. Complaint rate. The subdomain split. A screenshot of SPF, DKIM, and DMARC. Without those, a placement claim is guesswork.

After DNS, post whether the mail looked like the brand. If it did not, extract the brand in Brew. [Add your brand](https://docs.brew.new/get-started/add-your-brand). Put two Emails on the [canvas](https://brew.new/blog/email-canvas-workflow).

If you use an agent, check whether it can list last week's sends on [MCP](https://brew.new/mcp), and keep a human approval before any send. [Agent sending](https://brew.new/blog/agent-email-deliverability).

Split marketing and transactional mail onto separate subdomains.

## A sender week

Monday: authenticate. Tuesday: one test Email. Wednesday: seed. Thursday: review headers and complaints. Friday: decide if creation moves to Brew while Resend or Klaviyo still send.
