Ranking lifecycle emails by where users drop off
Members of the Growth work group each bring a ranking, then Brian Balfour folds them into one order keyed to the retention curve.
Updated
Rank emails by the part of the retention curve they move. For most products that puts the activation email first, then emails that deepen use and save renewals, with win-back to fully churned users last.
- Start where the curve drops hardest. Brian Balfour splits the retention curve into the first day, week and month, the middle, the long tail and resurrection, and says the email that matters most targets the steepest drop for your best segment. He would have onboarding emails push one core habit, not tour features, and would first check whether weak product-market fit or poor acquisition is the real cause, since no email fixes either.
- Fit the activation email to the product. Casey Winters says that for transactional products the first-order confirmation is the onboarding email, so it should carry a re-order prompt. Albert Cheng ranks a daily habit reminder first, tied to something the user already owns, like a streak or a Chess.com daily game where the opponent just moved. Lauryn Motamedi sorts products into three archetypes. She would lead with teammate and invite emails only where collaboration is core, and puts Albert's habit reminder at the top where multiplayer is optional.
- Move activated users to a second feature. Brian adds a depth email for the middle of the curve, because at HubSpot accounts that used more of its apps retained better. Casey would first plot a retention curve for each feature. If a feature's curve keeps falling toward zero, sending more users to it won't help retention.
- Build exit and renewal emails from the user's own use. Brian's final ranking puts trial-ending and renewal emails built around the user's own usage after the depth email, once there is enough volume to test them. Albert, whose Grammarly growth org included trials and billing, would build trial-ending and renewal emails around what the user did, and suggests putting the year in review into the renewal notice, since annual renewal notices are often legally required.
- Put a price on every send. Casey points to Pinterest, where the growth engineering team measured how much an unsubscribe hurt retention and so put a number on how many emails were too many. Albert would cut low-signal sends to protect the emails doing real work, and, for teams with big audiences, keep a small permanent holdout that gets no lifecycle email, read quarterly on retention; a small startup, he says, should follow Hila's order. Lauryn would keep an email only if its holdout moves a hard activation sub-metric rather than sessions. Hila Qu says a few hundred signups a week is too few for that, and would hold out on the first step, such as inviting one teammate, alongside calls with users.
- Win-back to churned users comes last. Brian's combined ranking ends with emails sent before users go dormant, then re-permission, then win-back to users who have fully churned. For re-permission, Hila cites a Facebook prompt to re-enable push that got over 25% of users through a five-step flow.

Frequently Asked Questions
How do you choose a startup's first growth channel?
Pick a channel the product can feed, test it with one narrow segment on a set budget and date, and judge it by how many users reach value and come back.
What should a founder check first when growth stalls?
That the data is right, then cohort retention split by segment and channel. If curves trend toward zero in every slice, fix the product before spending more on acquisition.
How do you tell a growth problem from a product problem?
Bring in a small batch of users from one clean channel and read their cohorts. If they activate and return but there aren't many, it's distribution. If they leave within the first week, product owns the fix.
What moves activation in a new user's first few days?
Find where users drop, then match the lever: pre-answer setup for users who stall, make the first action an earned win for users who feel nothing, and bring back users who got value.
Who should own acquisition and retention, growth or marketing?
Most members would split near signup, with marketing on channels and the promise and growth on the path to first value. The line still has to follow the growth model, and both teams judge channels by the cohorts that stay.
Should a growth team report to product or marketing?
Wherever the biggest lever is. For most product-led companies that is product, next to core rather than inside it, and once paid spend matters too, one growth leader owns acquisition and activation.
How do you bring back signups who went quiet?
Watch a few try the next step and fix where they stall, then test the message with and without the fix against a holdout, and count retained use rather than opens.
When should a product-led company add sales?
A founder can start working accounts where usage is spreading and retaining. A sales team follows once deals need security reviews and procurement that self-serve can't handle.
Which self-serve accounts should a sales rep call?
Ones big enough to pay for a rep's time, with use spreading inside the company and a need self-serve can't meet. Hold some flagged accounts back to check that sales added value.
Which early action should count as activation?
Use two measures: an early action onboarding can move as the team's operating metric, and a later repeat action to check that those users came back. Randomize the onboarding change so motivated users don't skew the read.
What makes a good north star metric for an early product?
A retention measure built from how often the problem occurs, the action that solves it and the user it describes, with activation as an input. Drop it if the team can raise it without users getting more value.
Should a new marketplace build supply or demand first?
Whichever side gets a buyer to a completed transaction while giving the supplier a reason to stay. Start in one narrow market and track matches, supplier earnings and repeat buyers.
When can a marketplace copy its first city?
When service holds after subsidies come down, a new manager can run the launch playbook without the founders, and the team knows whether the channel behind market one's demand starts warm or cold in the next market.
How should you test a landing page?
Show visitors what they searched for before the ask, start with the page's first clear funnel drop, and count activated users per visitor alongside signups.
Should a startup with a few dozen users stop acquisition?
Stop broad acquisition but keep a small hand-picked flow from one segment, onboard those users live, and count only return visits nobody prompted.
How does a B2B startup find its first paying customers?
Have founders sell by hand to one narrow buyer, starting with warm intros and asking for payment early. Then check who actually paid, and at what price, before choosing a channel to scale.
