What email service do you recommend for cold email, Zoho Mail or Google Workspace?

I've read your point about building a personal brand generator for consultants that does all the work for them, packages it into a file, and sends it to the prospect. It sounds really cool, but it's too high scale—if you plan to mass DM, you'll burn through resources. What do you mean by 'too high scale'? How much does it cost to generate one? Maybe around 25 cents? If you send it to 100 people, that's $25. What do you think your open rates on these pitches will be? Probably pretty big—you might connect with about 25 out of 100 people, so roughly a dollar per connection or meeting. I don't necessarily think this is a bad idea; that's what I'm trying to say. I'm looking forward to hearing more about it. Please post in the right channel; don't sweat it.

I want to start a cold‑email outreach but only have manual tools—what should I do?

I’ve been in the same spot. I started by rotating a handful of Gmail accounts—sometimes five—sending about ten cold emails a day from each. It’s not ideal, but it works to get started as long as your emails are well‑researched and the approach is solid. Gmail accounts have lower deliverability, especially new ones, so they need to warm up. You can also buy cheap inboxes (e.g., three Instantly airmail inboxes for around $4 each per month plus a domain) which gives you roughly 90 emails a day. Build a quick lead list, template your messages, and spend the first hour‑and‑a‑half each day sending them. You can also DM prospects. The key is to keep sending, refine your copy, and don’t worry too much about the tools at the start.

I have an automated cold‑email stack targeting small US businesses from Seoul; what advice do you have for getting my first client and how should I price my service?

I praised the stack and said the key is to treat outreach as a lever. Early months will have a low input‑to‑output ratio, but as you refine your process you’ll see massive leverage gains. I advised starting with Upwork to build credibility and earnings, then add cold‑email outreach in parallel. Don’t abandon the core lever (Upwork) while you experiment with outbound. Focus on improving average revenue per user—if you can tie your emails to an upsell or higher‑value service, you can justify higher pricing. Start with a modest package to get the first client, then increase rates as you accumulate case studies and results.

For a beginner doing cold email outreach, how many domains and email addresses per domain should I use, and what's a reasonable daily sending volume?

The creator recommends starting with 9‑12 mailboxes, which works out to roughly 30 emails per mailbox per day (270‑360 total). He suggests using about one domain for every three mailboxes, so 9‑12 mailboxes translates to 3‑4 domains. Domain registration costs around $5‑$10 each, and mailbox costs vary by provider—he mentions a 10% discount for Zapmail with code NYX. These are beginner guidelines from Maker School; you can increase volume if you’re not limited by resources.

What is the minimum daily email sending volume per mailbox and overall needed to effectively scale my cold email outreach, and how can I best leverage my current setup of eight mailboxes to reach 500–1,000 emails per day?

You cannot exceed about 30 emails per mailbox per day due to provider limits. To send 500 emails daily, divide 500 by 30, which gives roughly 16–17 mailboxes; you’re already using 18, so you can reach 540 emails per day. Therefore, the minimum per‑mailbox volume is 30 emails, and the overall capacity scales linearly with the number of mailboxes (mailboxes × 30). Your current results—236 emails sent, a ~2.6% reply rate (~six replies) and one meeting—are promising; scaling that volume will yield proportionally more replies and meetings.
