Hi John,

Saw the news about your new store opening in Berlin next month. Exciting!

Quick question about your Q2 product launch

[Interest — 開頭]
Hi Sarah,

Noticed you’re launching the new EcoSmart series in April. Congrats! Saw the teaser on your Instagram—the minimalist design looks fantastic.

[Desire — 中間]
Quick question: have you finalized your packaging supplier? We recently helped GreenTech reduce their packaging costs by 28% while switching to 100% recyclable materials (they were facing the same “eco-friendly but expensive” dilemma).

[Action — 結尾]
Would it be helpful if I sent over their case study? It’s a 2-page PDF with cost breakdown and timeline.

Best,
Tom

Hi Michael,

[Problem — 問題]
Saw your LinkedIn post about the 8-week lead time issue with your current supplier. That’s brutal, especially heading into peak season.

[Agitate — 激化]
I imagine it’s putting pressure on your inventory planning—and probably causing some tense conversations with your retail partners who need stock by mid-June.

[Solve — 解決]
We’ve helped 3 brands in similar situations cut lead times to 3-4 weeks by using our “Ready-to-Ship” program (we keep pre-produced inventory of top 20 SKUs based on your sales data).

Worth a quick chat? I can walk you through how it works in 10 minutes.

Best,

Subject: Idea for your EU expansion (re: certification delays)

Hi Emma,

[A — Attention]
Congrats on the MediaMarkt partnership! Saw the announcement on your LinkedIn—huge milestone.

[I — Interest + P — Problem]
Quick question: are you dealing with CE certification delays? I noticed your product line includes wireless chargers, which now require the new RED Directive compliance (changed in 2026).

[A — Agitate]
Most brands we talk to are hitting 10-12 week delays because testing labs are backlogged. That’s cutting it close if you’re aiming for a Q2 launch in Germany.

[D — Desire + S — Solve]
We’ve helped 3 US brands fast-track their CE certification to 3-4 weeks by using our pre-certified component library (saves 6 weeks of testing time).

[A — Action]
Want me to send over a quick comparison? I can show you the timeline difference and cost breakdown in a 1-page doc.
