What's newA little less busywork.

Hey Alex,Meet your new favorite shortcut.

Audience picked. Draft written. Still your decision.

Works with your agent. Claude Code, Codex, Gemini & more.

Credentials never pass through the agent.

See agent changes. Revoke access any time.

Pick your audience. Write something worth opening. Send it from a workspace that lives on your computer.

Supabase, Postgres, MySQL, MongoDB or Firebase. Your users become your audience, read through a login that can't write.

Build segments from your own data. Write in the editor or bring your own HTML.

Use SES, Postmark, Mailgun or SMTP. Rowsend adds no markup to your sends.

Addresses that bounce or mark you as spam are left out of every later send. If bounces or complaints climb, the campaign pauses itself so you can check the audience.

Logo, colors, buttons and social links in an editor that builds layouts mail apps can show. Save templates, or paste your own HTML.

Send yourself a test, schedule for later, send in batches, and pause or cancel a send that's under way. Set a daily limit for providers that cap you, and warm up a new domain from 50 emails a day to build trust as it grows to that limit.

A little help with the sending. A lot of control over everything else.

Let your agent do the prep.Claude Code or Cursor can draft campaigns and build segments. You review the email and press send.↗☾Scheduled sends go out while your computer is off.Turn on offline sending in Rowsend Cloud. From $90 a year.↗⌘Keep your keys to yourself.Your computer encrypts your provider keys. Agents never see them. Cloud stores them only when you enable offline sending.↗

Windows is coming soon. For now you write and send from a Mac. The sending service can run on any server, or on Rowsend Cloud.

Developers and small teams whose users live in their own database, who would rather pay for sending than for contacts.

Supabase, Neon, PlanetScale and any other Postgres. MySQL 8 or later and MariaDB. MongoDB, on Atlas or your own server. Firebase Auth, with fields from Firestore if you want them. Rowsend only ever reads, through a login that can't write, and your database stays the source of truth.

On your computer. Rowsend reads your users through a read-only database login and encrypts provider keys with your Keychain. Cloud only holds keys in memory while a send runs, unless you turn on sending while your computer is off.

Probably not yet. Loops and Resend are free at that size. Rowsend pays for itself once your list outgrows their free tiers.

Your license keeps working. Sending moves back to your computer or your own server.
