The email system

Eleven live emails across three products, in one voice. Which emails exist, every word of them, the HTML and the deliverability were all hers. 12,436 sends and not one spam complaint, because the system only speaks when a person does something.

Emails are the rest of the product experience.

Fans do not live on the platform they pay on; they live in their inboxes. On Penpal, fans pay a creator for a 1-on-1 conversation, so the emails were the rest of the product experience.

The product, as a fan actually sees it: an inbox.

We sent less, on purpose

On an earlier product we burned a sending domain and watched the mail stop arriving. So I already knew what this channel costs when you spend it badly.

Here it cost more. The magic link inside the email was the only way back into a conversation. Land in spam and you have not lost reach, you have locked the door on the product. The inbox was not a channel we marketed through. It was the door.

I built the whole thing anyway. Templates in March, twenty-seven more in April, the full celebrate-every-moment system: welcome sequences, day three, day fourteen, milestones at ten and twenty-five and fifty members, a weekly digest. Nine days later I deleted the engine that would have fired it. It was too much for a product that did not need it.

What was left follows one rule. The system only speaks when a person does something. Someone paid, someone replied, someone posted, someone asked to come back in. Nothing sends on a calendar. Open tracking stayed off, since opens lie and the pixel hurts deliverability. When Bailey missed a week, we sent nothing.

Here is the same 45 days for the two audiences that had anything on a calendar at all.

A creator’s first 45 days as a calendar. Sixteen emails are marked on dates and every one is struck through. Handwritten note: sixteen emails about nothing they had actually done yet. — The creator. Sixteen emails, every one on a date, none of them ever sent.

A Dome member’s first 45 days. Seven cells are filled and sent, six of them the weekly prompt; two scheduled nudges are struck through. Handwritten note: the only cadence that lived is the one a person had to write. — The Dome member. The weekly rhythm survived, because a person writes it every week.

The paying fan does not get a calendar at all. One scheduled email was ever designed for a penpal, a check-in at around day 45, and it went the same way as the rest. Everything else they receive is an answer to something. It was the creator, the person we most wanted to activate, where we had built a month and a half of talking to someone about nothing they had done yet.

the drip was mine too. easier to kill your own work than someone else’s.

What shipped

What did ship was mine to run: which emails exist, every word of them, the HTML, the deliverability. Engineering wired the sends.

The live email templates as one spread, Penpal, Dome and Sadie renders side by side — Eleven emails, three products, one voice. The part of the product that lives in the inbox.

Two more were never automated at all. The email for someone in distress, and the email for the person who answered them. Those a human sends, by hand.

The record

12,436sends

0spam complaints

11live templates

3products, one voice

12,436 sends, and nobody, not once, marked one as spam. I do not lean on the open rate; Apple prefetch inflates opens everywhere. A spam complaint is the number that cannot be faked, because a person has to decide to act against you.

It did not start clean. The first weekly prompt went to 645 people and 61 of them bounced, which is a tenth of the room hitting a dead address. Every weekly send after that runs at or under 0.2%. One bad send is where you learn what a list is.

Bounce rate on the weekly Dome bulk: 9.5% on the first send in March, 0.2% or lower on every send since — The first big send, and every one after it.

The email record set as a paper receipt: 12,436 requests, 12,147 delivered, 84 bounces, 4 unsubscribes, 0 spam reports — Eight months of it, on one slip of paper.

zero is the only number here i’d put on a billboard.
