A personalised message needs a fact worth mentioning. Adding a company name to a template does little if the rest of the message assumes a problem the company has never reported.
Give the research a boundary
Start with a filtered company list and choose a few accounts for review. Ask the assistant to examine the company's own website and record the URL and date beside each fact it plans to use. If it cannot open a source, it should say so.
Read this company's service pages. Identify a service our offer could support and cite the page. Separate what the page says from your interpretation. If you find no relevant connection, say that instead of inventing one.
This is a research prompt, not evidence about a real company. A growth figure or industry code can help select an account, but it doesn't tell you which project the company is working on or who owns the budget.
Write from the evidence you have
Suppose a service page genuinely describes on-site equipment maintenance. You could ask whether the team also needs help with a specific task your product handles. Link the offer to that published service; don't announce that you “noticed a new project” without a source.
Only include a saving or result when you can support it. If you have no verified percentage, explain the task your product handles rather than adding a number.
Before sending, check the recipient and the rules for that campaign. A general company inbox is not a named buyer, and a public address does not settle marketing permission. Let a person review the message before automating a sequence.
Choose companies in search, then keep research notes separate from the original register fields. That makes the assumptions visible to whoever sends the message.
