What You Should Pay by Operation Size

Solo SDR / Founder (5 Inboxes)

Should pay: $2-5/month for infrastructure (5 Puzzle Inbox Outlook). $80/month total stack.

Red flag if paying: $200+/month for 5 inboxes. You are overpaying.

Small Team (20 Inboxes)

Should pay: $40-80/month for infrastructure. $400-500/month total stack.

Red flag if paying: $1,000+/month. Investigate what you are paying for.

Growing Agency (100 Client Inboxes)

Should pay: $100-200/month for infrastructure. $700-1,200/month total stack.

Red flag if paying: $3,000+/month. Enterprise overkill for most agencies.

Large Agency (500 Client Inboxes)

Should pay: $500-1,500/month for infrastructure. $4-8K/month total stack.

Enterprise (1000+ Inboxes)

Should pay: $2-5K/month infrastructure. $15-30K/month total stack.

Per-Meeting Cost Reality

At each pricing tier, realistic cost-per-meeting:

Optimal stack (Puzzle Inbox + Instantly + Apollo): $5-15/meeting
Cheap stack (budget providers + warmup): $25-50/meeting
Enterprise stack (Outreach + ZoomInfo + InboxKit): $30-80/meeting

Counter-intuitively, the cheapest stacks often produce the most expensive meetings because deliverability suffers.

Cold email pricing should match your operation size. Overpaying wastes budget; underpaying wastes deliverability. Puzzle Inbox pricing scales appropriately from $0.35/inbox (solo) to enterprise tier.
