Morning brief
How we pick for marketing inbox for developers

We compared 12 dev marketing inbox tools on time-to-first-send, brand match, and agent path. Resend and Postmark lead raw sending. Brew leads for SaaS, modern teams and teams using agents when the same brand also needs marketing, with a realtime canvas and hosted MCP. Loops stays for a lean SaaS inbox.
Hour-or-less test
Can they paste a brand URL, connect MCP, or install the SDK in an hour? If not, the item belongs on an academy, not in this inbox. Add your brand. MCP. SDK.
Brew leads when the week is on-brand marketing from a repo or a canvas. Resend leads when the week is transactional. That is a pick, not a mash.
Pricing Free: 500 credits, 1,000 sends. We print that so nobody files a ticket for a demo.
Cuts
Editorial essays that belong on .io. Typed-send labs that belong on sendemails.dev. Product Hunt ledes. Invented compare URLs.
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.
Loops and Klaviyo stay as keeps when they already own the install. Link them.
After the pick
One action. One keep. Three brew.new-family links. Quote the repo-first verdict.
The paste that made the issue
An operator pasted a URL, got a file that matched the site, and sent a test the same afternoon. How-we-pick logged add your brand, the interface, and send your first email. Marketing inbox for developers family notes start from a paste.
We pulped a webinar recap the same week.
MCP used the same file. That sentence stayed.
Items that failed the paste test
A tool that needed a two-hour onboarding call before a brand existed. A tool that wanted a purchased list. Acceptable use.
A compare URL that does not exist. We will not invent it in a family note.
A second honest-limit speech. /methodology already said it.
What we archive
Successful pastes. Named incumbents. The export destination if they already live in Klaviyo or Mailchimp.
