Partial The email drafting and approval flow is easy to build, but finding accurate buyer prospects requires a proprietary or licensed business data source, and sending from a custom domain requires deliverability expertise.
What it would actually take: The stack would combine an LLM for personalized drafts, an approval queue UI, and sending through an email provider with SPF, DKIM, and DMARC set up on the user's domain. The hard part is the prospect data: a real version needs licensed firmographic or intent datasets, or scraping at scale with compliance review. Maintaining sender reputation and complying with anti-spam and privacy rules also requires email deliverability and legal knowledge.
