How to write a marketing letter to get clients example

Your marketing letter needs to solve a specific problem the prospect already knows they have, not pitch your services generically. Start by addressing their actual situation in the first sentence. If you're targeting e-commerce brands, you might open with "Your product pages are ranking for keywords that don't convert" rather than "We provide SEO services." This immediately signals you understand their world. Follow this with a brief statement of what typically causes that problem—in this case, maybe that most agencies optimize for search volume rather than purchase intent. By the second paragraph, you've positioned yourself as someone who sees what others miss.

The meat of your letter should focus on what they'll actually gain, not what you'll do. Instead of listing your services, describe the outcome: "We've helped similar brands increase organic revenue by 30% in six months by restructuring their content strategy around buyer keywords rather than informational ones." Include one or two specific examples from your portfolio that directly parallel their business model, even if you need to obscure the client name. This gives them confidence you can produce results in their industry. Keep the letter to one page—prospects scanning mail won't read more, and brevity forces you to cut fluff.

Close with a specific, low-friction next step rather than vague language like "let's talk." Instead, offer something like "I've put together a quick audit of your current keyword strategy—here's what I found, and here's what I'd change." Attach a two-minute summary showing you've actually looked at their site, not a generic template. This proves you're serious and gives them a concrete reason to respond. Include your phone number and suggest a specific day and time for a brief call, rather than asking them to schedule. People respond better to a directive than an open question. Make it feel like an invitation to a conversation, not a sales pitch, and you'll get far more qualified replies than standard form letters.
