The Prosumer Upgrade Ladder
Prosumer SaaS has the most natural upgrade path in the industry. Users discover your product personally, fall in love with it, and bring it to work. The email job is not to sell. It is to recognize where each user is on the ladder from casual to professional and give them the information they need for the next step.
A casual user who made their first project needs tips to get hooked. A power user who uses your product daily needs to discover advanced features. A power user who starts sharing with colleagues needs to know about team features. Each transition is a natural evolution, and email guides users through it at their pace.
Feature Discovery Is Revenue
In prosumer SaaS, most users never find more than 20% of your features. The features they do not find are the ones that would make them power users, and power users are the ones who upgrade to team plans. Email-driven feature discovery is directly tied to revenue.
The key is timing. Showing a new user an advanced integration is overwhelming. Showing a power user the same integration after they have been manually doing something the integration automates is a revelation. Behavior-triggered feature discovery emails that arrive at the moment of relevance are dramatically more effective than scheduled feature tours.
The Collaboration Trigger
The single most valuable event in prosumer SaaS is when a user collaborates with someone else. A share, an invite, a comment, a co-edit. Any of these actions signals that your product is being used professionally and that team features have a buyer.
When this event fires, your email should arrive within hours. Not with a hard sales pitch, but with a helpful overview of what team features unlock. The goal is to make the user think "oh, that would be useful" rather than "they are trying to upsell me." The difference is in the framing: team features as a natural next step versus team features as a sales target.
