ColdReach

What this does for you

ColdReach emails people who've never heard of you — potential customers — with a message written specifically for them, and follows up automatically until they reply. Read this first, honestly. Cold email is the one agent that can damage your business if rushed. If you blast strangers from your normal company email, email providers mark your domain as a spammer — and then your invoices, order confirmations, and replies to real customers start landing in spam too. That damage is slow to undo. So ColdReach is built to protect you: it sends from a separate domain, and it starts slowly on purpose. You cannot skip the warmup. Anyone promising you 1,000 cold emails on day one is selling you damage.

What you need first

• An Anthropic API key (5 min, ~$5–15/month)
• A second domain name, similar to your main one — if you're bakery.com, buy trybakery.com or bakery-team.com (10 min, about $10–15/year)
• 1–3 mailboxes on that new domain (Google Workspace or Microsoft, about $6–8 per mailbox per month)
• An app password for each mailbox (10 min — a special password that lets ColdReach send; Hi5Agents shows you where to find it)
• A list of people to contact — from ProspectorX, or your own CSV
• 2–4 weeks of patience for warmup

Flowchart

Step by step

1. 1

   Anthropic key (5 min)

   Settings → API Keys → paste → Test.

2. 2

   Buy your separate domain (10 min)

   Buy a domain that looks related to yours but isn't it. This is the domain that takes the risk, not your main one.

3. 3

   Create mailboxes (15 min)

   Set up 1–3 real mailboxes on that domain through Google Workspace or Microsoft 365. Use real-looking names — sarah@trybakery.com, not sales@.

4. 4

   DNS for the new domain (15 min + waiting)

   Add the SPF, DKIM and DMARC records your mail provider gives you. Hi5Agents shows you exactly what's needed and checks them for you. This tells the world your new domain is legitimate.

5. 5

   App passwords (10 min)

   Each mailbox needs an "app password" — a special password just for ColdReach, separate from your login. Your mail provider has a settings page for this; Hi5Agents links you to it. Paste each one into ColdReach → Requirements.

6. 6

   START THE WARMUP AND WAIT (2–4 weeks)

   Turn warmup on. ColdReach sends a small number of emails a day and slowly increases. This teaches email providers that your new domain is a real business, not a spam machine. Do not skip this. Do not raise the volume manually. The waiting is the work.

7. 7

   Load your list (5 min)

   Import a CSV, or push prospects across from ProspectorX. More detail per person means better personalisation.

8. 8

   Write your sequence (20 min)

   Two or three emails: the first ask, then a gentle follow-up, then a final one. ColdReach writes a personalised opening line for each person from their real details. Read ten of those opening lines before you send. If they sound generic, your prospect data is too thin.

9. 9

   Test on yourself (5 min)

   Send the sequence to your own address first. Check it arrives in the inbox, reads like a human wrote it, and the unsubscribe link works.

10. 10

    Start small (ongoing)

    Begin at low daily volume. Watch what comes back. ColdReach stops the sequence for anyone who replies, and sorts replies into interested, not interested, out of office, or unsubscribe.

• →Quality of list beats size, always. Fifty well-chosen prospects beat five thousand random ones.
• →Read the personalised first lines every week. They're the difference between a reply and a delete.
• →Keep it short. Three sentences and a clear question outperforms a sales letter.
• →Reply to interested people yourself, fast. The robot's job ended when they answered.
• →Never import a purchased list. It's the fastest way to burn the domain you just paid to warm up.
• →Never point ColdReach at your main company domain. That's exactly what the separate domain exists to prevent.
