#102 · How to Send 100,000 Emails Per Month (Cheapest Setup)

What are the best and cheapest cold email services for sending 100,000–200,000 emails per month?

Let's break it down. Sending 100,000 emails per month at 7 days a week equals about 3,333 emails per day. The recommendation is 20–30 emails per mailbox per day; using 30 gives roughly 111 mailboxes, which we round to 100 for simplicity. Options for 100 mailboxes include cheap inboxes at $2.50 each ($250/month), premium inboxes, inboxology, Zap Mail, and HyperTide. Adding Google Workspace and email software such as Instantly or Smartly brings the total to about $350 per month. Specific estimates: cheap inboxes $250/month, premium inboxes around $300–350/month plus any implementation fees. Instantly’s Super Search feature adds roughly $97/month. Overall, you could manage with approximately $350 per month.

How can I acquire clients using cold email tools that cost only $30‑$40 per month instead of expensive paid tools?

With a $30‑$40 monthly budget, you can still run effective cold email outreach. Use a low‑cost plan such as Instantly’s $37/month offering, plus a few mailboxes (about $50 total). Send roughly 1,000‑1,500 verified leads per month. A simple setup: one domain, three mailboxes, a two‑step sequence (45 emails on day 1, 45 on day 2) repeated over ~26 days, yielding ~1,200‑1,500 emails monthly. Replies require checking the mailboxes, but with only three it’s manageable.

What is the estimated monthly cost for using Chat GPT API for cold email?

The Chat GPT API cost for cold email is under $20 per month across my two companies, roughly $10–$20. You don't need to send emails manually; you can automate. Running a personalized cold email agent for the recommended outreach volume averages about $150 per month, but can be reduced to around $100 by using Instantly on the growth plan with Apollo for lead sourcing and Ampify scrapers at $0.75 per 1,000 leads, plus low-cost mailbox services like Zap Mail or Puzzle Inboxes. Instantly distributes emails across multiple mailboxes to avoid Google bans or throttling.

Should I focus on cold email or Upwork to reach $5‑10 k per month, and if cold email, what tips would you give to start?

You have three main approaches: cold email, Upwork, or both—and you can also upsell existing clients on follow‑up work. There’s no need to pick just one; you can do both and see which works better. If a client is already getting great value from your automation, pitch them on additional scope or an incentive‑based arrangement. To start with cold email, consider the offer size, niche, and daily email volume per mailbox, and test different tactics to see what yields results.

What setup do I need to start cold email outreach with a $120 budget?

Use a done-for-you mailbox provider; I recommend Zapmail (with affiliate code Nyx for 10% off). Get 9-12 mailboxes at about $3.50 each per month; with the discount that's roughly $33 total. Buy domains—one domain per three mailboxes—so about 3-4 domains at ~$10 each, adding ~$35. Set up Instantly: the $37 plan works if you're bottlenecked, bringing the total to about $105, leaving $15 for Make.com (or n8n) for personalization. You can also scrape leads for free using Apollo or Apify, then personalize them for a few dollars per thousand. Overall you can start with around $70.
