ConvertKit's engagement score can push you toward the wrong list
The afternoon sun through the office window hits your laptop screen just wrong, so you tilt it back and squint at a column of three-digit numbers next to subscriber emails—ConvertKit’s engagement scores, each one a tidy algorithmic verdict on who deserves your attention.
ConvertKit’s subscriber score ranks engagement—but optimising for it costs you money
Every subscriber gets a 0–100 score. The formula rewards opens and clicks, but it can steer you toward the wrong audience decisions.
ConvertKit calculates an engagement score for every contact on your list. It sits quietly in the subscriber detail view, a number between zero and one hundred that’s supposed to tell you who cares and who doesn’t. The score rises when someone opens or clicks. It decays when they ignore your sends. ConvertKit uses it internally to decide who gets shown in the Creator Network, and plenty of operators use it to segment sends or prune their lists.
The problem is that the score measures recency and frequency, not value. A subscriber who opens every email but never buys scores higher than a customer who skims subject lines, skips most sends, and renews their annual subscription every January. If you segment by score, you’ll send your best offers to your most attentive lurkers and suppress them for the people who actually pay you. The score also penalises anyone who uses an email client that blocks tracking pixels—which is everyone on Apple Mail with default settings, plus a growing share of Gmail users. High-value subscribers on privacy-forward clients look disengaged, so they get down-ranked or excluded.
The score isn’t useless. It’s a reasonable signal for identifying completely cold contacts—anyone below 20 after six months probably isn’t coming back. But treating it as a proxy for subscriber quality will pull your attention toward opens and away from revenue. If you want to rank your list by value, tag purchases and calculate lifetime value yourself. If you want to measure engagement, track reply rate or survey completion instead of opens. ConvertKit’s score is one input, not a business metric.
TACTIC
Why subscriber count is a vanity metric that builds the wrong business
Growing your list to 10,000 subscribers feels like progress until you realise half of them never open, a quarter bounced months ago, and the remaining 2,500 generate less revenue than the 300 who actually care. Optimising for total subscriber count pushes you toward lead magnets that attract freebie-seekers, broad topics that dilute your expertise, and platforms that charge per contact whether those contacts are worth anything or not. The operators who escape this trap early are the ones who measure engagement rate, reply rate, conversion rate, and revenue per subscriber instead of treating list size as the scoreboard.
TOOL CHOICE
When to route transactional email separately from your marketing sends
Most operators send password resets, order confirmations, and newsletter broadcasts through the same ESP. That works fine at 2,000 subscribers, but it creates risk once you scale or start seeing deliverability wobbles. Marketing emails can damage your sending reputation if engagement drops; transactional emails need to land in the inbox no matter what. Splitting them across two services—your main ESP for newsletters, something like Amazon SES or Postmark for transactional—keeps your critical emails isolated from reputation fluctuations and gives you finer control over which infrastructure handles which type of message.
RESEARCH
How to find the traffic Google doesn’t show you in Search Console
Your analytics show a spike in sessions, but Search Console’s performance report doesn’t account for half of them. The missing traffic is probably coming from Google Discover—the personalised feed on Android homescreens and the Google app. Discover can send thousands of visits in a day, but it won’t appear in your normal Search Console queries unless you open the separate Discover report. Most operators never check it, so they miss the signal that tells them which headlines, images, and topics are working outside traditional search. If you publish frequently or cover news-adjacent beats, this is the report that shows you what’s actually reaching people.
