The AI cold email writer that uses real lead context
The Kavex AI cold email writer takes the data you already have on a lead and turns it into outreach that reads like you wrote it by hand. Feed it a business name, location, website notes or anything else in your list, set the goal, tone and language, and it returns a personalized subject line and body per lead. It is how a small team sends a hundred genuinely different emails in the time it used to take to write five. You pay per email generated.
Sign up to useWhat it does
The AI cold email writer works from your lead context rather than a generic template. For each row you provide — company name, city, category, a website detail, a recent signal — it produces a subject line and a short body that references that specific lead, so no two emails read the same.
You stay in control of the angle. Set the campaign goal, the tone, the language and a sender profile, and every email is written to that brief. Switch the language to Dutch, French or German and the copy is written natively in that language, not translated word for word.
It is built for volume without sounding like volume. Upload a list and the writer returns each row with its personalized subject and body attached, ready to drop into your sending tool. Ask for more than one variant per lead and you get distinct angles to test against each other.
The quality of the writing tracks the quality of the input. A row that carries only a company name produces a competent but general email; a row that also names the city, the industry and a specific detail — a recent hire, a product line, a review theme — produces an opening that reads as genuinely researched. That is why the AI cold email writer pairs naturally with the scrapers: the context they collect becomes the raw material the writer turns into copy. You can also set a fallback instruction for thin rows, so a lead with little context still gets a usable, on-brief email rather than an awkward blank.
Use cases
- Outbound teams writing a hundred unique cold opens overnight instead of burning a day on copy.
- Agencies producing on-brand outreach for several clients at once, each with its own tone and goal.
- Founders A/B testing two angles per lead to learn which message earns the most replies.
- International sellers localising a campaign into Dutch, French or German without a translator.
Sample output
Each lead returns a ready-to-send subject and opening. A generated batch looks like this:
| Company | Subject line | Opening line |
|---|---|---|
| North Studio | Your Amsterdam team and faster handoffs | Saw North Studio is scaling its design work — most studios your size lose hours in client handoff. |
| Bright Labs | A quick idea for Bright Labs onboarding | Bright Labs ships fast, so your onboarding is probably the bottleneck — here is a thought. |
| Varzace | Cutting Varzace support tickets | Berlin SaaS teams your size usually see support volume spike right after a launch. |
How it works
The AI cold email writer is powered by Google Gemini. For every lead, your context fields and your campaign brief are assembled into a structured prompt, and the model returns a subject and body shaped to that brief. The output is parsed back into clean columns, so what you download is data, not a wall of text.
Generation is configurable per job: goal, tone, language, sender profile and the number of variants. Because the AI cold email writer reads each lead individually, a larger and richer input list produces sharper, more specific copy — the personalization is only as good as the context you feed it.
Frequently asked questions
Which languages can it write in?
You set the language per job, and the email is written natively in it — Dutch, French, German and English among them — rather than machine-translated from an English draft. The tone and idiom match the language you choose.
Can I get more than one version per lead?
Yes. Set the number of variants and the writer returns that many distinct angles per lead, which makes it easy to A/B test subject lines and openings across a campaign.
What input does it need?
It works from whatever lead context you upload — company name, location, category, website notes or signals. More relevant context produces more specific copy, so a richer list is worth the extra columns.
How do results export?
Each lead downloads as a CSV row with its personalized subject line and body in their own columns, ready to map straight into an outreach or mail-merge tool.
