New lead welcome nurture (post form-fill drip)

Outcome. New contacts who fill a top-of-funnel form get a 4-email welcome drip over about two weeks that introduces the company and nudges toward a second conversion, with no manual follow-up.

When to use it / when not to

• Use when a form is the first real touch (ebook, newsletter, low-intent contact form) and there is no immediate sales intent.
• Use to warm a contact before they see sales-facing content or get a rep outreach.
• Do not use for high-intent forms (demo request, pricing request, contact-sales). Those need fast human follow-up, not a drip. See lead-routing for that pattern.
• Do not stack this on a contact who is already mid-sequence in another nurture track. Check the nurture_track property first.
