Listener Q&A: Email lists, customer feedback, and SaaS valuations

Executive overview

Founders often wonder whether collecting emails through product sign-ups gives them permission to market across unrelated projects. The answer sits in the gap between what's legally permissible and what's actually respectful of subscribers.

This episode tackles four listener questions: when opt-in email crosses into spam territory, how to evaluate selling as an affiliate versus building, how to value a SaaS during a co-founder split, and which feedback mechanisms yield the most useful signal.

Be more conservative than the law requires — transparency about why someone is receiving an email does more for trust than any legal technicality.

Opt-in email and spam

• CAN-SPAM (US) permits emailing any opt-in subscriber about anything until they unsubscribe — but legal permission is a low bar.
• The better test: if you received this email three years after opting in, what would you need to read to not feel spammed?
• If the two topics are related enough to bridge in a paragraph, email them with clear context at the top.
• If the topics are completely unrelated, send a single opt-in invitation rather than assuming consent.
• Building related products creates a durable advantage: any one list can be co-promoted with just a few sentences of framing.
• Dismiss internet absolutists (especially on Hacker News, Reddit, Stack Exchange) who label all bulk email as spam — they don't reflect how the real world works.

Affiliate vs. building a competing product

• Recurring affiliate commissions for SaaS can work as a stair-step step-one business, but won't typically reach $10–30K/month.
• High-touch approach (paid onboarding, consulting, migration services) generates more revenue and more learning than passive affiliate links.
• Low-touch affiliate funnels require inbound traffic — if you're starting from scratch, ranking against incumbents takes a long time.
• The real value is learning: does this space need another tool, or is the existing one good enough?
• Optimise for learning over money at this stage; revenue from affiliates alone is likely to be slow and limited.

SaaS valuation during a co-founder split

• Engage a broker for a third-party valuation: Quiet Light Brokerage (quietlight.com) or FE International are the right starting points.
• Multiples vary based on growth rate, churn, and market conditions — "it depends" is the honest answer.
• Buyouts between co-founders are typically priced below open-market value, because the remaining founder absorbs all the risk.
• Above ~$1M ARR, Discretion Capital and growth-oriented private equity firms can write larger checks to fund a buyout.
• Below $18K/month, private equity interest is unlikely; selling the whole company via Acquire.com is a clean exit alternative.

Collecting customer feedback

• Video or phone calls are the highest-fidelity option: body language, tone, and spontaneous reactions are impossible to replicate in text.
• Loom recordings are a useful middle ground — higher fidelity than email, no scheduling friction.
• One-on-one email is preferable to surveys unless you have a large list (thousands) that makes individual calls impractical.
• Surveys only work at scale; with a small list, people don't fill them out and assume no one reads them.
• The hardest part isn't the mechanism — it's getting people to respond at all.

Choosing between HOA boards and property managers

• HOA boards are committees of volunteers; group decisions slow the sales cycle and increase complexity.
• Property managers likely offer a single decision-maker, which makes closing faster and more predictable.
• Run parallel cold outreach to both segments early — non-response before you have a product is a signal of how hard the space will be to sell into.
• Test paid ads (Google, Facebook) to see which segment is actively searching for a solution.
• Find where each group gathers online (Facebook groups, Slack, trade pubs, industry events) before committing to a channel.
• Going after two closely related verticals simultaneously is not a hard no if both use the product in the same way.
• Every assumption is a hypothesis until validated; 50–70% confidence is enough to act.
