### Personalization Examples
**SaaS Company**:
> Hi Sarah,
>
> I saw Acme Software raised a Series B last month (congrats!) and is hiring 15 sales reps according to LinkedIn. That kind of growth usually creates onboarding bottlenecks.
>
> We helped ChartMogul and Segment cut new rep ramp time by 40% without adding headcount to training teams.
>
> Worth a quick call to see if we could help Acme do the same?
**Enterprise**:
> Hi John,
>
> Noticed your team at GlobalTech recently posted 8 cloud security engineer roles. When my previous clients scaled that fast, credential management became a nightmare.
>
> We've helped Fortune 500 IT teams like yours at Cisco and IBM automate access controls—cutting security incidents by 75%.
>
> 15 minutes to discuss your approach?

## 💡 Pro Tips
1. **The 3-Second Rule**: Prospect should understand value in first 3 seconds of reading
2. **One CTA Only**: Don't give multiple options; one clear next step
3. **Mobile-First**: 50%+ of emails opened on mobile; keep it scannable
4. **No Attachments**: Use links instead; attachments trigger spam filters
5. **Real Reply-To**: Use your actual email, not no-reply@ (and actually reply!)
6. **Personalization Tokens**: Use sparingly; obvious automation kills trust
7. **The P.S. Works**: PostScripts get read; use for secondary CTA
8. **Remove Unsubscribes**: No formal unsubscribe needed for 1-to-1 prospecting
### What to Avoid
**Spam Trigger Words**:
- "Free", "Limited time", "Act now"
- "$$$$", "Make money"
- ALL CAPS anything
- Too many exclamation points!!!
**Design No-Nos**:
- Images (especially logos)
- HTML-heavy templates
- Multiple font colors/sizes
- Long links (use link shorteners)
