Why

Fewer than 10 inbound replies per month from cold email means your bottleneck is top-of-funnel volume and follow-up cadence, not deal management. With a team of 2–3 doing outreach over a single channel (email), a CRM would mostly sit empty. The question isn't "where do we track deals" — it's "are we sending enough sequenced touches to the right people, and are we replying within an hour when someone bites."

What you actually need

1. Instantly or Smartlead (~$37–$97/mo) — cold email sending + inbox rotation + automated follow-up sequences. This is the actual job: get more replies. Pick one.
2. Google Sheets (free) — one tab "Replies 2026" with columns: Date / Prospect / Company / Role / Stage (Replied → Call Booked → Submitted Candidate → Closed) / Owner / Next Action. One row per warm reply only.
3. A habit — the 1-hour reply SLA — when someone replies to a cold email, one of you responds within 60 minutes during business hours. Cold-reply interest decays fast; this single habit doubles booked calls.

Do this today

Sign up for Instantly (instantly.ai) or Smartlead (smartlead.ai), connect your sending domain, and load your existing prospect list into one campaign with a 4-step sequence (Day 0, 3, 7, 12). Then open Google Sheets and create the "Replies 2026" tab with the seven columns above. By tomorrow morning every reply lands in one row owned by one person, and your sequencer chases the non-responders without you remembering to.

What to ignore

Skip Recruit CRM, Manatal, and Bullhorn — those are candidate-side ATS tools for agencies placing 10+ candidates/month, not cold-outbound shops still trying to break 10 replies. Skip HubSpot Sales Hub ($20/seat looks cheap until contact limits hit) and Apollo's all-in-one pitch — at <10 replies/mo, a "CRM + sequencer + database" suite is 80% unused features you're paying for.

What doing nothing costs you

At under 10 replies/month split across 2–3 people with no shared visibility, you're almost certainly double-emailing prospects or letting warm replies cool for 48+ hours — the specific compounding loss is burned domain reputation and prospects who decide you're disorganized before the first call.

When to revisit this

When you consistently hit 30+ warm replies/month or sign your second retained search — then Recruit CRM or HubSpot Free starts earning its keep.
