How cold email software works, step by step
From your own SMTP inbox to a personalized email for every prospect, in three steps.
| Prospect | Company | Subject the AI wrote | Result |
|---|---|---|---|
| j.harper@example.com | Northwind Ltd | Your Q3 ops hiring push | Sent |
| m.okafor@example.com | Acme Retail | Stock counts across 12 sites | Sent |
| l.dubois@example.com | Contoso Freight | Overnight routing in Lyon | Sent |
| r.iyer@example.com | Globex Labs | The assay backlog you posted | Sent |
| s.novak@example.com | Initech Systems | Rolling out to the new depot | Refused |
Connect your SMTP inbox
Link a mailbox you already own (Gmail, Outlook, Amazon SES, or any SMTP provider). We open a real connection and log in the moment you save, so you find out here whether the details work. Campaigns then leave from your own mailbox, so the sending domain and the reputation stay yours.
- Any SMTP provider supported
- Connection and login tested before anything is sent
- Password stored encrypted, never shown again
- Two inboxes on Starter, unlimited on Pro and Enterprise
Import your prospect list
Paste your list straight in, one prospect a line: the email address, and optionally first name, company, role and one free context note. That context column is what the AI writes from, so the more specific it is, the more specific the message. ColdMailer does not source or scrape prospects for you.
- Paste your list, one prospect a line
- Up to 500 prospects per campaign
- Email, first name, company, role and your own context note
- Rows without a valid email address are skipped, repeats queue once
| Company | Role | Context |
|---|---|---|
| Northwind Ltd | Ops Lead | Opened a second depot in Leeds |
| Acme Retail | COO | Stock counts across 12 sites |
| Contoso Ltd | VP Ops | Hiring three dispatchers |
| Globex Labs | Head of Ops | Posted about an assay backlog |
Let the AI write, review, then send
Write your brief once and the AI writes a subject line and a body for each prospect from their own company, role and context, never a merge tag in a template. Read them, edit anything you want by hand, then send from your own inbox and see the delivery result for every prospect.
- A unique subject and body per prospect
- Every message yours to edit before it goes out
- Sent from your own inbox, replies come back to you
- Delivery result recorded for every prospect
Hi Jordan,
Saw Northwind opened a second depot in Leeds, usually that is the point dispatch scheduling starts to hurt.
Worth a short call?
