How many emails can one run make?

The Emails ruler runs 1 to 20, but the drip renderer caps at 12, so asking for 20 returns 12. At 1 you get a single send. Above 1, one cheap planning pass lays out the arc and gives each step a subject, preheader, angle and delay. Every message is then written by the same full renderer a single email gets, four at a time. The viewer stacks them on a Day N rail.

Will it hold up in Outlook?

The HTML is written for mail clients rather than browsers: presentation tables, every style inline, no style block for Outlook to strip, web-safe fonts, a 600px body and a table-cell CTA button in place of a padded anchor. Images carry alt text and explicit width and height, and an unsubscribe link is required. Download the .eml from the viewer and open it in Gmail, Outlook or Apple Mail before you send anything.

Can I lock my own subject line?

Yes. Anything you type into Subject line or Preheader reaches the model as a hard constraint marked do not rewrite, and comes back word for word. Left blank, the model writes its own subject at 42 characters or under so it survives mobile truncation, plus a preheader under 100 characters that extends the subject rather than repeating it. On that written path, ALL CAPS, repeated exclamation marks and the words Newsletter and Update are banned.

What does it know about my brand?

Pick a project in the header dropdown and leave Use this project's details On, which is where it starts. Every email run then loads that project's brand, research, strategy, funnel and active reference pack into the prompt before a word is written, so it writes on your voice and keeps off your banned-phrase list. Leave the header on Quick tools and there is nothing to read, so the model works from your brief alone.

How do I get it into my sending tool?

The viewer header has copy buttons for Subject, Preheader, HTML and Plaintext, so you can paste into Klaviyo, Mailchimp, HubSpot or anything that takes raw HTML, plus a .eml download for client testing. Inside a project you can send from here instead: Email Studio lists the email in the Compose rail, and Send broadcast takes a name, a from address, a reply-to and an audience, then sends now or schedules.

Does a sequence cost more than one email?

Yes, close to linearly. Each email in a drip is its own full render, so a five-step sequence costs about five single emails plus the one cheap planning pass. The Generate button carries that count, reading Generate 5 at five, so a batch never fires silently. The prefill will not raise Emails on its own either: it returns 1 unless you say sequence, drip or nurture, or name a number.

The brief here is called What the email must drive, and it takes the outcome, the reader and the one action. Emails is a ruler: leave it at 1 for a single send, set it to 5 and the button reads Generate 5, which plans a drip and then writes each message in full. Goal starts on Trial activation and also holds Book a demo, Direct purchase, Re-engagement and Announcement. Tone starts on Warm + personal. Leave Subject line and Preheader blank and the model writes both. Type them and they come back word for word. CTA URL and From name are the two fields no prefill will guess. You get table-layout HTML with inline styles, a plaintext mirror and a .eml you can open in Outlook.

How it works

Four steps, start to finish

The tool is open above. This is the short version of what to do with it.

01 / 04
Say what it drives
The brief is labeled What the email must drive, and Generate stays disabled while it is empty, with the footer naming the field it is waiting on. Name the outcome, who is on the list and the single action. The placeholder: welcome SaaS trial signups, get them to their first aha in one click.
02 / 04
Set Emails and Goal
Both sit under the Goal heading. The Emails ruler starts at 1, a single send, and runs to 20. Anything above 1 becomes a timed drip, typically day 0, 1, 3, 6 and 10. Goal starts on Trial activation and also offers Book a demo, Direct purchase, Re-engagement and Announcement.
03 / 04
Pick Tone, or a subject
The Voice and subject group holds Tone: Casual + direct, Warm + personal as the default, Punchy marketer, Founder-honest, Professional + formal. Subject line and Preheader sit under it and both are optional. Blank means the model writes a 42-character subject and a preheader that extends it.
04 / 04
Fill CTA URL yourself
CTA URL and From name are the two fields no prefill will touch, since a guessed link sends real people somewhere wrong. Type the real destination and it becomes the button link and the footer view-in-browser link. From name rides the sender line and the .eml header you download.
