Everyone makes cold email sound like it needs a $2,000 per month budget. It does not. Here is the exact minimum viable stack I used when I started 18 months ago. Total cost under $150 per month.
Inboxes: 5 PuzzleInbox Google Workspace inboxes at about $22 per month. Pre-warmed, DNS set up, ready to send. Five inboxes at 15 to 18 sends per day each is 75 to 90 cold emails per day. That is 1,500 to 1,800 per month.
Sending platform: Instantly Growth plan at $37 per month. Connects to Google Workspace via OAuth. Basic A/B testing, good analytics, simple UI. Plenty of features for someone starting out.
Data: Apollo free tier to start. 50 exports per month free. Once you see reply rates, upgrade to the $49 per month plan for 1,000 exports.
Email verification: ZeroBounce pay-as-you-go. About $0.008 per verification. On 2,000 contacts per month that is $16.
Total: roughly $75 to $120 per month depending on your Apollo plan.
What you do not need starting out: Clay, Lemlist, Saleshandy, any AI personalization tool, a dedicated copywriter, a fancy CRM integration. Add those when you are booking meetings and have budget to reinvest.
At 1,800 emails per month with a 3 percent reply rate that is 54 replies. Converting 25 percent to meetings is 13 to 14 meetings per month from a $120 stack. That math works.
Start simple. The technology is not what makes cold email work. Your list quality and your copy make cold email work. Spend the first month getting those right on a minimal stack before adding tools. Most people buy Clay before they have figured out their ICP. That is backwards.
