You know the drill. You sit down on a Sunday night, promise yourself you’ll send 20 cold emails this week, and by Friday you’ve sent four. Not because you’re lazy, but because writing each one from scratch, finding the right person, then remembering to follow up takes forever. So outreach becomes the thing you’ll do “when things slow down,” which of course never happens.

Here’s the good news. You can hand most of that work to a system that drafts personalised emails, sends them at the right time, and chases the non-responders for you, all while you’re doing literally anything else. The two tools doing the heavy lifting are Claude AI for the writing and Make.com for the plumbing. Let’s walk through exactly how it fits together for a New Zealand business.

What does it actually mean to send cold emails automatically?

Automating cold email doesn’t mean blasting the same generic template to a thousand strangers. That’s spam, and it gets you blocked fast. It means building a workflow that does the repetitive parts for you while keeping each message genuinely tailored.

A proper automated cold email system handles four jobs. It reads your list of prospects, writes a unique email for each one based on their business, sends it from your inbox at a sensible pace, and follows up a few days later if they don’t reply. You stay in control of the strategy and the approval. The robot just does the typing and the remembering.

The difference between this and the old “mail merge” approach is the writing. Instead of swapping a first name into a fixed template, Claude reads what each prospect actually does and writes an opening line that proves you paid attention. That’s the part that used to take you ten minutes per email. Now it takes a few seconds.

Is it legal to send cold emails in New Zealand?

Yes, with conditions, and this is the bit most people skip. Cold email in New Zealand is governed by the Unsolicited Electronic Messages Act 2007. Get it wrong and the penalties are real: fines can reach $500,000 NZD. So it’s worth two minutes of attention before you automate anything.

The Act recognises a category called “deemed consent” that covers most B2B outreach. If a business has published an email address publicly (on their website, for example), there’s no note saying they don’t want unsolicited messages, and your email is relevant to their role or business, you’re generally allowed to contact them. You can read the official guidance from the Department of Internal Affairs before you start.

Three rules keep you safe. Every email must clearly identify who you are and how to contact you. Every email needs a working, easy unsubscribe option. And when someone opts out, you have to honour it and stop emailing them. Build those three things into your automation from day one and you don’t have to think about them again.

How do Claude AI and Make.com work together?

Think of it as two specialists. Claude is the copywriter. Make.com is the office manager who keeps everything moving on schedule.

Make.com is a no-code automation tool. You build a “scenario” by dragging connected steps onto a canvas, and it runs them in order without you touching anything. If you’re new to it, our guide on what Make.com is and what it costs in NZ is a good starting point. The free plan handles 1,000 operations a month, which is plenty to test a cold email system.

Claude plugs into Make.com through its API. At the moment in the workflow where an email needs writing, Make.com passes the prospect’s details to Claude with an instruction like “write a short, friendly cold email to this business about X.” Claude writes it, hands it back, and Make.com drops it into the send step. No copying and pasting, no tabs open everywhere.

How to set up automated cold emails step by step

You can build a working version of this in an afternoon. Here’s the order I’d do it in.

1. Build your prospect list in a spreadsheet. One row per business, with columns for company name, contact name, email, and one detail about them (a recent project, their location, what they sell). That last column is what makes the personalisation land.
2. Connect the spreadsheet to Make.com. Use a Google Sheets module as the trigger so the scenario picks up new rows automatically.
3. Add a Claude step to write the email. Feed it the row’s details and a prompt that sets the tone, the length, and the one thing you want the email to ask for. Tell it to keep things short and human.
4. Insert an approval gate (optional but recommended early on). Route the draft to yourself in Slack or email first, so you eyeball the first few dozen before they send. Once you trust it, remove this step.
5. Send through your email provider. Connect Gmail or Outlook and add the unsubscribe line and your business details to every message.
6. Add a wait, then a follow-up. Have Make.com pause three days, check if they replied, and if not, send a short nudge. Most replies come from the follow-up, not the first email.
7. Cap your daily volume. Set the scenario to send a limited number per day so you stay under the radar and protect your sender reputation.

That’s the whole machine. If you’ve already set up other automations like automated quote follow-ups, this will feel familiar, because the follow-up logic is nearly identical.

What results can you actually expect?

Let’s be honest about the numbers, because the hype around cold email is wild. The average cold email reply rate in 2026 sits around 3.4%, down from about 8.5% back in 2019, according to industry benchmark data. Inboxes are crowded and people are quicker to ignore anything that smells like a template.

This is exactly why automating the writing matters more than automating the sending. Personalised emails see roughly a 32% higher response rate, and campaigns that go beyond “Hi {first name}” into genuine, signal-based personalisation can hit reply rates of 15 to 25%. That’s the gap Claude closes for you. It writes a real opening line for every prospect at the speed of a mail merge.

The other lever is deliverability. Proper email authentication and sensible sending limits can lift response rates by up to 30%. Practically, that means warming up a new sending address slowly, starting at five to ten emails a day and building over a few weeks, and never firing hundreds at once from a fresh inbox. Slow and steady beats a one-day blast every time.

My honest take on automating cold outreach

Automation is a force multiplier, not a magic wand. If your offer is weak or you’re emailing the wrong people, automating it just means you’ll get ignored faster and at scale. The system is only as good as the list and the offer you feed it.

So my advice is to earn the automation. Send 20 cold emails by hand first. Find out what actually gets a reply from your market, what objections come back, what wording makes people open. Then teach that to Claude in your prompt. When you automate something that already works, you get a quiet, reliable stream of conversations. When you automate a guess, you just get faster silence.

And keep the human in the loop where it counts. Let the machine draft and send, but you decide who’s worth a personal reply when they respond. That’s where the deals actually happen.

Frequently asked questions

Do I need to know how to code to set this up?
No. Make.com is built for non-technical users, and you connect everything by dragging modules and filling in fields. The Claude step is just a prompt you write in plain English. If you can use a spreadsheet, you can build a basic version of this.

How much does it cost to run in New Zealand?
You can start free. Make.com’s free plan covers 1,000 operations a month, and Claude’s API is pay-as-you-go, usually a few cents per email or less. Most small operations run a starter cold email system for under $50 NZD a month, scaling up only as volume grows.

Will automated emails land in spam?
They can if you send carelessly. The fix is to warm up your sending address, keep daily volume modest, authenticate your domain, and write genuinely useful, personalised emails. Treat your inbox reputation like a credit score and it stays healthy.

How is this different from buying an email list?
It isn’t about where the names come from, it’s about how you contact them. You still need a relevant reason to email each business, a clear sender identity, and an unsubscribe option. Bought lists are often low quality and risk breaching the rules, so building your own targeted list almost always works better.

Can I use a tool other than Claude or Make.com?
Absolutely. ChatGPT can do the writing and Zapier can do the automation if you prefer them. The principle is the same: one tool writes, one tool moves the data and sends. We use Claude and Make.com because the quality and cost balance works well for NZ small businesses.

How many follow-ups should I send?
Two or three is the sweet spot. One initial email and two short follow-ups spaced a few days apart captures most of the replies you’re going to get without becoming annoying. After that, leave them be and move on to fresh prospects.
