Letter Announcing New Service Template

In plain language: The opening block identifying who is sending the letter, who it is addressed to, and when it was written.

Common mistake: Using a trade name instead of the registered business name in the sender block — this creates inconsistency with contracts or invoices the recipient may already have on file.

In plain language: A brief, specific reference line that tells the reader at a glance what the letter is about before they read the opening paragraph.

Common mistake: Writing a vague subject like 'Exciting Update' instead of naming the service — vague subject lines reduce open rates on printed mail and cause email attachments to be skipped.

In plain language: States the purpose of the letter directly and immediately: a new service is being launched and the recipient should know about it.

Common mistake: Opening with background about the company instead of the announcement. Readers scan the first sentence to decide whether to keep reading — bury the news and you lose them.

In plain language: Explains what the new service is, how it works, and what problem it solves — in plain language the reader can act on.

Common mistake: Listing features without connecting them to outcomes the client actually cares about. A feature description tells readers what you do; a benefit description tells them why it matters to them.

In plain language: Personalizes the announcement by connecting the new service to the recipient's specific situation, industry, or prior relationship.

Common mistake: Sending a generic mass letter without any personalization signal — even one sentence referencing the recipient's industry or prior engagement significantly improves response rates.

In plain language: Briefly establishes credibility by referencing relevant experience, early client results, certifications, or industry recognition tied to the new service.

Common mistake: Omitting this paragraph entirely for new services with no track record. If you lack client results, reference team credentials, partnerships, or the methodology behind the service instead.

In plain language: Tells the recipient exactly what to do next — schedule a call, reply to the letter, visit a URL, or attend a launch event.

Common mistake: Including multiple competing calls to action (call us, email us, visit the site, attend the webinar) without prioritizing one — readers who are asked to do everything typically do nothing.

In plain language: A professional sign-off with the sender's name, title, and contact details, maintaining a tone consistent with the existing client relationship.

Common mistake: Closing with an impersonal block signature and no warm sign-off sentence. A single sentence expressing genuine interest in the recipient's response closes the letter on a human note and increases reply rates.

A letter announcing a new service is a formal business communication a company sends to clients, partners, or prospects to inform them of a new offering. It introduces the service, explains its benefits, and invites the recipient to take a specific next step — such as scheduling a call or visiting a website. It is typically one page and sent by post, email, or as a PDF attachment.

Send it as close to the service launch date as possible — ideally one to two weeks before the service becomes publicly available so existing clients feel they are being given early access. If the service is already live, send the letter immediately rather than waiting. Delays mean clients may hear about the new offering from a competitor or a third party first.

For most B2B contexts, email is the standard delivery method — it is faster, trackable, and easy to act on. A printed letter sent by post stands out in high-value client relationships where formality matters, or when the new service carries a premium price point. For the strongest impact, send a printed letter to top-tier clients and email to the broader list simultaneously.

One page is the standard target. Readers of business correspondence typically allocate 30 to 60 seconds to a letter before deciding whether to act. A tight, well-structured single page with a clear call to action outperforms a two-page letter that pads the service description. If you need to explain the service in depth, link to a brochure or landing page rather than expanding the letter itself.

Yes, with a small adjustment to the opening paragraph. For existing clients, the letter can reference your prior relationship. For cold prospects, open with a concise statement of who you are and why the service is relevant to their business before moving into the announcement. The structure, call to action, and closing remain the same in both cases.

Generally, no. A service announcement letter is designed to generate interest and prompt a conversation — not to close a sale on paper. Including a specific price before the reader understands the full value can cause premature rejection. Instead, reference that pricing details are available upon request or link to a pricing page for self-service readers.

A letter is a personal, direct communication addressed to a specific individual or segment — it has a salutation, a body, and a signature. A brochure is a broadcast marketing piece designed for general audiences with no specific addressee. Letters carry more perceived weight in formal B2B relationships and are better suited to high-value, named client lists. Use the letter to open the conversation and the brochure as an enclosure or follow-up resource.

Yes. A letter without a follow-up call or email typically generates a response rate of 1 to 5% on its own. A structured follow-up — a phone call or email three to five business days after the letter arrives — can double or triple that rate. Reference the letter in your follow-up to give the conversation immediate context.
