You don't need to spend thousands to run cold email. Here's a complete system that costs $117.50 per month and generates 20+ meetings monthly.

Infrastructure: 15 PuzzleInbox pre-warmed Google Workspace inboxes. Cost: $67.50/month (at $4.50 per inbox). These arrive with DNS configured and warmup completed. You connect them to your sending platform and start sending day one. 15 inboxes is the sweet spot for a solo operator or small team.

Domains: 5 domains. Cost: ~$5/month amortized (buying .com domains at ~$12/year each). Three inboxes per domain keeps your per-domain sending volume conservative. PuzzleInbox sources domains for you if you don't want to handle this yourself.

Sending platform: Instantly Growth plan. Cost: $30/month. Handles sequencing, A/B testing, scheduling, and reply management. Connects to your PuzzleInbox accounts via OAuth.

Data: Apollo free tier. Cost: $0. 10,000 email credits per month. More than enough for 15 inboxes sending 12 emails each per day.

Email verification: ZeroBounce pay-as-you-go. Cost: ~$15/month at this volume. Keeps your bounce rate under 2% which protects your inbox reputation.

Total: $117.50 per month.

At 15 inboxes sending 12 emails each per day, you're pushing 180 cold emails daily. That's about 3,960 emails per month. At a 3.5% reply rate, you're looking at ~139 replies per month. Roughly 40% will be positive, giving you ~56 interested prospects. Convert 40% of those to meetings and you're at 22 meetings per month.

22 meetings per month for $117.50. That's $5.34 per meeting. Try getting that cost per meeting from any other channel. Google Ads will charge you $200 to $500 per meeting. LinkedIn Ads even more.

This is the exact stack I recommend to anyone starting cold email on a budget. You can scale from here by adding more inboxes ($4.50 each) as your pipeline grows.
