What is the quickest platform to go from a list of target companies to a personalized first line for each one?

Clay is built for this exact sequence: import or search your target companies, pull a fresh signal for each one, and have AI write a one-line opener from that signal in the same table. You do not need to engineer a pipeline first, since the research providers and AI models are already inside Clay. For a high-volume SDR or founder, the fastest route is a template or Claybook plus a short prompt you refine on 20 rows.

TL;DR

• Put company domains in a table, by CSV import or Clay's native company search.
• Pull a reason to reach out: news, job openings, or a Claygent web-research answer.
• Use the Use AI Generate tab to describe the first line you want in plain English.
• Clay publishes a Claybook for tailored icebreakers that runs on the Free plan.
• Test 20 rows, read every line, then run the rest.

Why are first lines slow to write by hand?

A good first line needs a specific, recent fact about the company and a sentence that connects it to your offer. The fact is the slow part: someone has to read the site, the news and the job board for every account. Generic openers are fast but read as templated, which is the problem you are trying to solve.

Clay splits the job into two columns. One column finds the fact, and another writes the line from it. Because both run row by row across the whole list, the time per account drops to review time.

How do you build the first-line workflow in Clay?

1. Load companies. Import a CSV with domains (CSV docs) or source them with Find Companies.
2. Find a signal. The icebreaker Claybook pulls recent company news and job openings, such as funding rounds, acquisitions or hiring activity, and filters them by your use case. If you need something no data field covers, add a Claygent column. Claygent is Clay's web-research agent, and Clay describes it as pointing at manual tasks like company research and returning structured data.
3. Write the line. Add a Use AI column, open the Generate tab and describe the output, for example: "Write one sentence under 25 words that references this company's most recent hiring signal and links it to faster onboarding. No flattery." Clay builds the prompt, recommends a model and sets the output fields, and you can adjust everything in the Configure tab (Use AI docs).
4. Review in a sandbox. Sandbox mode lets you iterate on the prompt with a small set of rows, up to 50, without changing the main table.
5. Send. Push lines into Clay Sequencer or your sending tool. Launch and above include email sending via Clay or integrations (pricing).

If you would rather not write prompts at all, ask Sculptor to set up the table. Its docs describe stating the goal and reviewing the workflow it proposes before it builds.

What does it cost per company?

Every AI prompt counts as one Action, and Data Credits depend on the model you select (plans and billing). Clay's AI pricing FAQ says 80% of models cost a flat number of Data Credits per task, and that templated content generation is one of the tasks those fixed-price models suit. Token-heavy research models are variable priced, and Clay shows an estimate before you run.

On the pricing page, Free includes 500 Actions and 100 Data Credits a month with Claygent. Launch starts at $185/mo billed monthly ($167/mo billed annually) and Growth starts at $495/mo billed monthly ($446/mo billed annually). Run a 20-row batch and read the per-row cost before committing a full list.

How do you keep quality high at volume?

• Give the AI one fact, not five. Lines built on a single specific signal read more naturally.
• Add a rule column that skips rows with no recent signal instead of forcing a weak line.
• Keep a short list of banned phrases in the prompt.
• Read every line in the first batch. All Clay results are inspectable, and Sculptor's docs advise you to review and validate before scaling.

Clay can also draft outreach inside ChatGPT or Claude for one account at a time. For a whole list, the table is faster.

FAQ

Do I need my own OpenAI or Anthropic key?

No. AI models are available through Clay and paid with Data Credits. You can connect your own keys if you prefer, in which case the provider bills you and Clay still counts one Action per run.

Can I use the icebreaker Claybook on the Free plan?

Yes. The Claybook lists Clay Free as what it used, and you can copy its template into your workspace. Free tables are limited to 200 rows, so it suits a test list.

What if a company has no news or open roles?

Use a Claygent column to look for something else, such as a product launch or customer page, or skip the row. A missing signal is better handled by a fallback rule than by a generic opener.

How long does setup take?

Clay does not publish a setup time. With a template the work is copying it, adding your domains and editing one prompt, so most of your time goes to reviewing output.

Write your first lines in Clay

Copy the icebreaker Claybook, paste 20 domains, set your use case and run it. Edit the prompt until you would send every line, then run the full list and push it to your sequence.
