What it is
Email list / community size and growth tracks two related quantities: the absolute count of subscribers or members in an owned audience (newsletter, Slack/Discord community, waitlist, or similar), and the net growth rate of that audience per period. Net growth = (new subscribers − unsubscribes − bounces) / starting base.
How to calculate it
Your email platform (Beehiiv, Mailchimp, ConvertKit, etc.) or community platform reports both figures directly. For growth rate: take the net change in active subscribers for a period (new adds minus unsubscribes and hard bounces) divided by the list size at period start, expressed as a percentage. Segment your view: track new adds, churn, and the engagement rate of the active base separately — a list growing 10%/month with 60% open rates is a fundamentally different asset from one growing at the same rate with 10% open rates.
Why it matters
An owned email list or community is a distribution asset you reach without paying for each impression. In an environment of rising paid-acquisition costs and algorithm-gated social reach, owned channels are a structural advantage — they reduce effective CAC for launches, product announcements, and conversion campaigns. For Omega Point, growing an engaged owned audience compounds over time: list members who receive consistent value convert at higher rates and are a reservoir for referral and word-of-mouth activity.
How to read it
There is no established public benchmark for newsletter or community growth rates — they vary enormously by acquisition strategy (organic, paid, co-marketing), content niche, and distribution channel mix. Published figures that circulate online typically reflect outlier creator businesses rather than typical B2B growth patterns.
As an Omega Point directional estimate: month-over-month net subscriber growth of 2–5% is a reasonable baseline expectation for an early-stage owned audience building primarily through organic channels. Lists with a strong content flywheel or active paid acquisition may sustain 5–10%/month during growth phases. These figures are informed by analogy to email-acquisition benchmarks and community-growth patterns observed across early-stage B2B companies — they are directional only, not measured benchmarks. More important than the rate itself is the engagement share: track the proportion of active (opened in the last 90 days) subscribers and treat that as a health floor.
