LeadEngine.ai gives you three powerful copywriting modes to help you craft effective, high-converting cold emails—whether you're a copywriting pro, a busy founder, or just need speed and scale.
Each mode offers a different level of personalization, automation, and AI-enhanced variation. Here’s how they work:
For testing and sending variations with intelligent automation.
What it is:
AI Spintax allows you to write email templates using smart AI spintax—but with an AI twist. Instead of just rotating text randomly, our system uses AI to rewrite your template, creating unique combinations for each email send.
Why it’s powerful:
Effortlessly create multiple variations of subject lines, openers, or full bodies
Improve deliverability by reducing duplicate content across sends
Best for:
Teams running volume-based outreach who want better engagement and inbox placement without rewriting emails manually.
For personalized outreach at scale—no manual research needed.
What it is:
Dynamic AI uses real-time scraping of the prospect’s website and LinkedIn profile to craft hyper-personalized emails for every contact. Just set the tone and let our AI do the heavy lifting.
Why it’s powerful:
Auto-generates custom openers and messages that sound like a human researched the lead
Saves hours of manual personalization
Boosts replies by making every email feel 1-to-1
Best for:
Founders, sales reps, and marketers who want to stand out in the inbox with contextual, relevant emails—but don’t have time to research every lead.
Example:
“Hey Alex, I came across {{company_name}} and noticed you're working on {{pulled insight from website}}. Really impressive…”
→ Dynamic AI automatically fills in the blanks.
For simple templates and quick sends with manual spintax.
What it is:
This mode gives you a straightforward email editor that supports manual spintax (e.g., {{Hi|Hey|Hello}}
), but without AI optimization or personalization. Checkout this article to learn more about basic spintax:
