New Feature Announcement Letter

When to use this template

Reach for a New Feature Announcement Letter when the message benefits from being preserved in writing rather than left to memory or a phone call. The structure below is designed for the typical case — read it through once, replace the bracketed fields with your own details, and trim anything that doesn't apply to your specific situation. For more on the conventions specific to sales & marketing letters — when a written record matters, what tone to strike, and what the recipient is reading for — see our Sales & Marketing Letters writing guide. The plain-language conventions used throughout this letter follow the same writing principles many professional editorial style guides recommend: short sentences, concrete nouns, and a single clear request per paragraph.

The letter

Dear [First Name],

[One opening line that names the offer and the deadline — for example, "For the next 7 days only, our new [Product] is 30% off for everyone on this list."]

Here's why we think you'll like it: [one sentence on the benefit, in their words]. We built it after hearing the same request over and over from customers like you, and the reception has been better than we hoped — [a number that proves it].

[A one-line call to action with a clear verb and link/deadline.]

Thanks for being part of [Company Name]. If this isn't for you right now, no worries — we'll be back with something else soon.

Best,

[Your Name]
[Your Title] · [Company]

What's specific about New Feature Announcement Letter

What makes this New Feature Announcement Letter different from the other sales & marketing letters in this category is the specific situation it was written for. The structure, tone, and pacing of the body all assume that situation — which is why the template will land more naturally if you keep the structure and only change the content inside the brackets. Resist the temptation to rearrange paragraphs; the order they appear in is the order most sales & marketing letters readers expect, and reordering them quietly costs the letter some of its credibility.

The most common mistake people make when sending a New Feature Announcement Letter is over-explaining. The recipient does not need the entire backstory; they need just enough context to act on the request, the notice, or the message. If you find your draft running long, look for paragraphs that exist only to justify the letter to yourself rather than to inform the reader, and cut them. A page is the natural ceiling for almost every sales & marketing letters, and most are stronger at half a page. Writers who want a deeper dive into the structural conventions can also consult the broader professional correspondence handbook we maintain for this category.

Finally, before you send, run through the small checklist that applies to every letter in this category: have you named the operative date, named the specific person or amount, set a clear next step, and signed with a real title? Those four items are what move a draft from a personal note into the kind of professional correspondence that gets taken seriously. The body below is already structured around them — just don't lose them in your edits.

About Sales & Marketing Letters in general

Sales and marketing letters are read the way email is read — fast, on a phone, with the reader looking for a reason to delete. The templates in this section are designed to survive that scan. Subject-equivalent opening lines do the heaviest lifting; the offer comes early; and a single, specific call to action sits at the close. Long marketing letters underperform short ones in nearly every measured channel, and adjective-heavy letters underperform letters that name a number, a deadline, or a specific saving. The structure here is deliberately compact. If you find yourself wanting to add a fourth paragraph of background, write it instead as a follow-up letter for the prospects who reply to the first one. Cut the original until what is left is irreducible.

Tips for sending this letter

1. Lead with the offer, not the brand.
2. Make the call to action a single sentence with a verb and a deadline.
3. Use a number — percentage, dollar amount, or duration — in the first two lines.
4. Personalize at least one element beyond the recipient's name.
5. Keep the letter to under two hundred words for cold outreach.
6. Test two versions before scaling a campaign — the better-performing letter often surprises.
7. Include an unsubscribe path on every marketing letter sent at scale.

Why it matters that this is in writing

Of all the channels available for this kind of message — phone call, text, instant message, casual email — a written letter remains the most enduring choice when the matter has weight. A printed or PDF letter signals that you took the time to compose your thoughts, structure them, and put them in front of the recipient in a form they can return to later. That signal alone often shifts the tone of the response in your favor, because the recipient understands they're being asked to engage seriously rather than offer a quick reply.

It also creates a record. Six months from now, if you need to reference this exchange, you'll have an exact copy of what you said and when you said it. That matters most in situations involving employment, money, housing, and any contract — the kinds of situations where memory alone is not enough. Even when the recipient is a friendly party, the discipline of writing a real letter forces you to think through your position more carefully than a quick message ever would. That extra thinking is the real value of using a template like this one as a starting point: it gives you the structure, so you can focus on the substance.
