Subject: Quick question about your marketing
Hi Sarah,
I hope this email finds you well. My name is John and I'm reaching out from MarketingCo. We help companies like yours improve their digital marketing.
We've helped many clients achieve great results. I'd love to schedule a 15-minute call to discuss how we can help your company too.
Would you have time this week?

Subject: The Shopify SEO gap I noticed in your Q4 strategy
Sarah, noticed TechStart just launched the new product configurator. Bold move during Q4 — but without supporting SEO, you might be leaving $47K/month on the table.
On the Drift project, we identified a similar gap and recovered 127% organic traffic in 60 days.
The main question is probably whether this applies to your stack. I put together a 3-min audit — want me to send it over?
