No.
You don't need a CRM. You need Ghost used properly, and a tiny sponsor tracker on the side.
What's really going on
You have two very different businesses under one roof. One is 3,850 readers you want to double — that's a segmentation and lifecycle job, and Ghost handles it natively with tags, tiers and filters. The other is a handful of high-yield sponsors and partners — that's a relationship job, maybe 20-40 live threads a year, with no admin to feed a pipeline. A CRM built for sales teams would sit empty and guilt you.
What to do instead
- Ghost (you already pay for it) — lean on tags and newsletter segments. Tag on signup source, tag on upgrade, tag on open behaviour. That IS your subscriber "CRM".
- Capsule CRM (free tier, UK-friendly) — one board for sponsors and partners only. Company, contact, renewal date, last touch. Nothing else. Under 250 contacts stays free — check current pricing if you grow past it.
- Habit — every Friday, 15 minutes, open Capsule and move anything you haven't touched in 30 days into "nudge this week".
First action today: open Ghost admin → Members → Filters. Build one saved filter for "free sub, signed up >60 days ago, opened >3 emails, not paid". That's your warm upgrade list. Write one email to them this week.
What you're being oversold
HubSpot Free sounds tempting because it's free, but you'd spend a weekend wiring it to Ghost and then get pushed toward Sales Hub within a quarter — wrong shape for a two-person shop with no admin. Pipedrive is built for reps working a daily pipeline; your sponsor cycle is quarterly, it'd go stale in a month. The real cost of doing nothing isn't lost subs — Ghost will catch those. It's forgetting to follow up with a sponsor at renewal and losing one of the few deals that actually funds the business.
When to revisit this
When sponsor conversations pass roughly 15 live at once, or when you hire someone whose job includes chasing them.
The part worth getting right
The one call your numbers hinge on: is your growth plan mostly converting existing free subs to paid, or mostly pulling in new free subs at the top? If it's conversion, every hour goes into Ghost segments, upgrade sequences and paywall tuning — Capsule barely matters. If it's top-of-funnel, sponsor and partner relationships become your main growth channel, and that little Capsule board quietly turns into the most important tool you own. Pick wrong and you'll spend a year polishing the side that wasn't the lever.
