| Do | Don't |
|---|---|
| Keep 3-7 words | Write novel-length subjects |
| Use {{first_name}} or {{company}} | Over-personalize ("Saw you on LinkedIn...") |
| Create curiosity | Mislead with clickbait |
| Be specific when possible | Use generic templates |
| Test lowercase | Use ALL CAPS |
Examples:
| CTA Type | Example | When to Use |
|---|---|---|
| Soft | "Thoughts?" | Early in sequence |
| Medium | "Worth a quick chat?" | Middle of sequence |
| Direct | "15 min this week?" | After engagement signals |
| Breakup | "Should I close the loop?" | Final email |
One CTA Per Email: Never give multiple options.
| Token | Example | Priority |
|---|---|---|
| {{first_name}} | "Hey Sarah," | Required |
| {{company}} | "saw {{company}}'s recent..." | Recommended |
| {{title}} | "As a {{title}}, you..." | If relevant |
| {{industry}} | "In {{industry}}, we see..." | For segmented |
| Level | Effort | Impact |
|---|---|---|
| Basic | Low | {{first_name}}, {{company}} |
| Medium | Medium | + recent company news, role-specific |
| High | High | + mutual connections, specific insight |
Rule: Personalize opening line at minimum. Rest can be templated.
