No.
You don't need a CRM.
What's really going on
You have 3,850 subscribers and a mission to double them. That is a marketing and analytics problem, not a pipeline problem. Ghost already segments your readers. A CRM would sit empty next to it, or worse, become a second contact database you forget to update. The only "sales" surface you have is a small set of high-yield sponsors — and that's a spreadsheet's worth of relationships, not a pipeline.
What to do instead
- Ghost (you already pay for it) — lean hard on its segments and tags. Tag by referral source, topic clicked, and paid-vs-free. That IS your CRM for readers.
- Capsule CRM (free tier, UK-friendly) — a single board for sponsors and partners only. One card per company, next-touch date, last conversation. Nothing more.
- Habit — every Friday, 20 minutes, update the sponsor board and note who to nudge next week.
First action, today: open Capsule, create one board called "Sponsors & Partners", and add every current and prospective sponsor with the date you last spoke to them. Half an hour, done.
What you're being oversold
Someone will pitch you HubSpot because it's free, then upsell Marketing Hub the moment you cross a contact threshold — you'd be paying to store the same emails Ghost already holds. Pipedrive is built for sales teams chasing deals; you have no sales team and no deals to chase. Apollo and the outbound stack are irrelevant — you're inbound by design. Doing nothing on the CRM front costs you nothing. Doing nothing on sponsor follow-through costs you real money, because those relationships are few, high-yield, and easy to let go cold with no admin.
When to revisit this
Revisit when you're juggling more than ~20 active sponsor conversations at once, or when you hire someone whose job is partnerships.
The part worth getting right
The real fork is this: is your growth engine going to stay social-led, or will newsletters start pulling their weight? If social stays king, you need a lightweight analytics habit tying social referrals to Ghost signups — a CRM is noise. If newsletters become the growth loop, you need to double down on Ghost segmentation and maybe a referral tool, still no CRM. Get this call wrong and you'll spend the next year feeding a tool that doesn't feed you back — or worse, migrating off it when you finally hire someone who actually needs one.
