What’s the best way to find good emails for cold outreach and locate direct phone numbers for decision‑makers?

A cost‑effective way is to use cheap lead‑scraping services like Appify, Lead Finder, or Pipeline Labs. They charge roughly $1‑2 per 1,000 leads, so you can scrape 6‑7 k leads for about $10, then verify and end up with 3‑4 k usable contacts. For phone numbers, use enrichment platforms that add phone data to company records; many of the scraped leads already include numbers. Once you have the list, you can email everyone, then run a follow‑up call campaign—send the email first, then call to reference the email and increase perceived effort compared to typical cold‑call teams.

What are your thoughts on using cold calls for outreach, and should I change my approach?

Cold calls are far less efficient than cold emails these days. Roughly only 10% of the effort you put into calling translates into real results because many leads never answer, you often talk to gatekeepers, and even qualified prospects are frequently busy or uninterested. In contrast, a cold email campaign can reach thousands of leads, pre‑qualify them, and give you a list of warm prospects before you ever pick up the phone. Cold calls can still have a place, but they’re much more manual and low‑yield compared to email outreach.

I'm starting an AI service agency and need to land a few clients for testimonials. What's the best way to find good emails for cold outreach? Also, how do you track down direct phone numbers for the actual decision maker? Appreciate any tips you have.

I feel like I've already answered this, but to be clear, I would use Apify's 1.5 per 1k scraper, which gets you about 1,000 leads for roughly $1.50 to $2. Then I'd run them through Million Verifier to validate emails—I'm not affiliated with them. That would give me about 60-70% valid emails, meaning you'd spend around $3 to $4 per thousand leads on average. That includes phone numbers too, though they're sparser than emails. You could also enrich with something like Lead Magic for phone enrichment if needed, but I wouldn't worry about that right now. [gasps and sighs]

How can I do cold outreach with little money? I'm starting an agency and can't afford cold email tools; I'm using cold calling instead. Can you suggest low-cost tools or a quick guide?

You don't need money to do cold outreach; everyone has a free mailbox (email). You just need to figure out the email address and be willing to trade some time for potential money. As a beginner with time but little money, you can manually write and send cold emails—each taking 3–4 minutes, allowing 10–20 per day, which is less than an eighth of a typical workday. Tools aren't required; they only speed up a process that's already potentially profitable. You can also send cold DMs via Loom video on LinkedIn, X, Instagram, TikTok, etc.

Would you recommend adding cold calling to the outreach stack?

No, I don't think so. When you cold call, very few calls actually reach a qualified prospect. For example, out of 100 cold calls, roughly 50 are disqualified immediately, another 30 either don’t pick up or get routed to a secretary, and the remaining calls often hit busy or dismissive decision‑makers. The synchronous nature of cold calls limits your ability to pitch effectively. Instead, I recommend using customized video recordings as a modern replacement. Send a personalized video via email; decision‑makers check their inbox frequently, and the video can be watched on their own time, delivering high value and a no‑brainer offer. This approach works better than cold calls and even beats cold email because the offer stays in the inbox and can be reviewed later across time zones.
