Stage by stage

Every stage opens its own tools and Notion artifact. Nothing is auto-expanded. Tap what you want to read.

01 · Sources

Every signup lands in one place

Signups from Webflow forms, purchase events from Stripe, quiz completions from ScoreApp. All three write to Notion Subscribers DB with a source tag and the user raw event data.

02 · Segmentation

Tag by behaviour in real time

n8n watches events. A purchase over $500 tags the user VIP. A quiz score in the top 20% tags them hot. 14 days of inactivity tags them at-risk. Segments are Notion filters, not a separate tool.

03 · Content

Drafts from your brand voice

Brand voice library in Notion (tone rules, 20 past winners, do-not-write list). Claude drafts 3 variants per email. Human approves top 2. The library grows as winners replace laggards.

Manual version · 8 h/wk · $2,000/moAutomated · 1 h/wk · $40/mo
04 · Sequencing

The right send tool for the segment

Customer.io for behavioural, Klaviyo for ecommerce, Mailchimp for broadcast, Brevo for transactional. n8n picks the right tool per segment so you do not pay for every platform.

05 · Reporting

Attribution back to the segment

Every Stripe charge links back to the send that triggered it. Revenue per segment per month visible on one Notion page. Claude writes the Monday digest. Underperforming segments auto-surface.

Time saved

~25 hours/week of a fractional email marketer (briefing, writing, segmenting, reporting) collapses to ~3 hours/week of review.

ROI

Replaces a $3,500/mo fractional email marketer plus ~$1,500/mo of segmentation ops. A team running 4 campaigns a month sees revenue-per-subscriber climb 20-40% in the first quarter because the cadence doubles and the brand voice sharpens.
