Formal first message to a new contact
Formal on WhatsApp means clear and respectful of the reader’s time — not the long salutations of a letter. Say who you are, why you are writing, and what happens next, inside four lines.
The first message decides whether there is a second one. On WhatsApp that first message arrives in the same list as the reader’s family and friends, which is why the formal register people carry over from email reads badly here and gets ignored. Below are messages for the situations businesses actually face — a first approach to a new contact, an introduction to a group, a welcome after someone opts in — written the way they work on this channel, with a note on what to change before you send.

Formal on WhatsApp means clear and respectful of the reader’s time — not the long salutations of a letter. Say who you are, why you are writing, and what happens next, inside four lines.
Lead with the outcome the reader wants, not the year you were founded. One specific proof point beats three adjectives.
Post this as the first message after creating a group. It sets the purpose and the rules, which is what prevents the group turning into noise and emptying out.
Send within seconds of the opt-in, while the intent is live. Confirm what they signed up for, set frequency, and give the opt-out. That last line is not optional and it protects your quality rating.
This is the automated reply that fires on a first inbound message. Answer the two questions every new enquiry has: is anyone there, and how long will this take.

State who you are, why you are writing and what happens next, in about four lines. Formal on WhatsApp means clear and respectful of the reader’s time, not the long salutations of a letter — "Dear Sir, I hope this message finds you well" reads as a mass send here. Use the person’s name, one specific reference to why you are contacting them, and one question.
Three things: who you are, why you are writing to this person specifically, and what you want them to do next. Lead with the outcome the reader cares about rather than your company history, and include one concrete proof point — a number, a named client, a guarantee. Keep it under 60 words so it is readable in the notification.
For an admin creating a group, the first post should set purpose, rules and timings: what the group is for, what may and may not be posted, when messages go out, and how to reach you directly instead of in the group. Groups that do not set this in the first message fill with forwards and empty out.
Yes, on anything sent to a list. A visible "reply STOP to unsubscribe" line is required practice and it protects you: people who cannot find the exit report the number instead, and reports feed the quality rating that governs how many customers you are allowed to message per day.
If your business starts the conversation on the WhatsApp Business Platform, yes — any business-initiated message needs an approved template, greetings included. If the customer messaged you first, you are inside a 24-hour service window and can reply freely in your own words. The automated greeting that fires on an inbound message falls in the second case.
You can, and it will underperform. The greeting that works references something true about that reader — the page they enquired from, the event you met at, the product they were looking at. Where you cannot personalise the fact, at least segment: a first-time enquiry and a returning customer should not get the same opening line.
