Spec 00 — Predictive email, one workspace

Not louder email — better-timed email.

Delphi learns from every open, click and purchase, then tells you what to send, to whom, and when. Sequences, segments and newsletters live in one calm workspace, explained in words you already know.

Who sends with Delphi

Spec 01 — The idea
Good email isn’t a bigger send. It’s paying attention to who opened, who bought, and who went quiet.

Delphi does the paying attention, then tells you what it noticed in plain sentences.

Sent every week by teams at

  • Lowell & Finch
  • Hollowell
  • Nightjar
  • Quillon
  • Dunmore
Spec 02 — What’s inside

One workspace that answers what, to whom, and when

Five tools, one screen each. Nothing to stitch together, nothing to guess at.

Spec 02.1 · Sequences

Draw the journey once. Delphi runs it.

Drag steps onto a canvas and add a branch for people who didn’t open. You see exactly who goes where before anything sends, and nothing goes out until you press publish.

Spec 02.2 · Segments

Lists that keep themselves tidy.

Describe who you mean in plain rules: bought twice, opened this month. The group updates as people click and buy, so you never send to a list that went stale last week.

Spec 02.3 · Send time

Each person gets it when they usually read.

Delphi learns the hour every subscriber tends to open and sends to that hour. You still pick the day. The timing, which is the part nobody can do by hand for thousands of people, is handled.

Spec 02.4 · Newsletters

A newsletter editor that remembers your brand.

Set your colours, fonts and logo once in a brand kit. Every new email starts from a saved template and already looks like you, so a Thursday newsletter takes minutes instead of an afternoon.

Spec 02.5 · Deliverability

A quiet alert before a risky send, not after.

Delphi checks your sending domain and every draft for spam risk, then says in one sentence what to change. You fix it while it’s still a draft and your sender reputation stays untouched.

Spec 03 — Getting started

Connect the list, shape the plan, press send.

You can do all three in a single sitting. Delphi starts from your history, so the first suggestions already reflect how your subscribers behave.

Step 01 / Connect

Bring your list and your store.

Import subscribers from a file or connect your tools. Delphi reads past opens, clicks and orders so it begins with history instead of a blank page.

  • File import
  • Opens & clicks
  • Order history
Step 02 / Configure

Say what you want to happen.

Pick a ready-made sequence or draw your own, choose a segment, and attach a brand kit. A preview shows who gets which email before anything is sent.

  • Sequences
  • Segments
  • Brand kit
Step 03 / Launch

Press send, then let it learn.

Delphi picks the hour for each person and keeps watching what happens. Next week’s suggestions come out a little sharper than this week’s.

  • Send-time prediction
  • Spam-risk alerts
  • Weekly read-out
Spec 04 — Connections

Works with the tools you already open every morning.

Connect the places your customers, tasks and invoices already live, and Delphi reads from them instead of asking you to re-enter anything.

  • Airtable
  • Jira
  • Trello
  • Asana
  • PagerDuty
  • Xero
  • Salesforce

Spec 06 — Field notes

In their words

“Our Thursday newsletter used to go out at ten because that’s when we were ready, not when readers were. Delphi now sends to each person at their usual hour, and I’ve stopped second-guessing the schedule.”
— Priya N., Lifecycle Lead, Hollowell
“I drew the whole welcome series on one canvas, with the ‘didn’t open’ branch right beside it. I could explain it to my manager in a minute.”
— Marguerite L., Retention Manager, Nightjar
“The spam-risk alert caught a subject line before it went out. It told me what to change in one sentence, and I changed it.”
— Callum D., Founder, Quillon
Spec 07 — Next step

Your next email already has a best moment. Let Delphi find it.
