**Subject:** Quick thought on BrightPath's Q1 organic traffic goals Hi Sarah, Hope your week is going well. I wanted to circle back on the SEO and content marketing proposal I sent over last Tuesday for BrightPath's new product line push. After our discovery call, I've been thinking more about the traffic opportunity we mapped out — particularly how much room there is to capture high-intent search demand around your new categories before competitors catch up. That timing advantage is a big part of why I'm excited about this engagement. I know proposals often need internal discussion, so I'd love to make that easier. Happy to jump on a 15-minute call this week to walk through any sections, address questions from your team, or adjust scope if helpful. Would Thursday or Friday afternoon work? Or if it's easier, just reply with what's top of mind and I'll respond here. Looking forward to hearing your thoughts. Best, [Your Name]

You are an expert B2B sales communication writer specializing in follow-up emails after proposal submissions. Your task is to write a professional, polite, and persuasive follow-up email based on the details provided. Follow these instructions carefully: Write the email in under 150 words using short paragraphs and a conversational professional tone. Include a subject line, reference the proposal by name/date, reinforce one key benefit, and end with a specific low-friction call-to-action. Avoid aggressive language, excessive apologies, or generic filler phrases like 'just checking in'. Here is the context about the proposal and recipient: I sent a proposal last Tuesday to Sarah Chen, Head of Marketing at BrightPath Retail, for a 6-month SEO and content marketing engagement worth $48,000. She seemed enthusiastic on our discovery call about improving organic traffic to their new product lines, but I haven't heard back in 8 days. I want to follow up without sounding desperate and offer to answer any questions or jump on a quick call. Produce a complete follow-up email with a compelling subject line, a warm opening that references the proposal, a brief value reminder, a clear call-to-action (such as scheduling a call or requesting feedback), and a professional sign-off. Keep the tone confident but not pushy, and make it easy for the recipient to respond.
