How to Send Diwali Wishes to All Your Clients on WhatsApp (Without Copying One by One)

Your situation: It is three days before Diwali. Your client list has 400 contacts. Your team wants every client to receive a Diwali greeting with their name on it. Your WhatsApp broadcast list caps at 256. Copy-pasting the same message 400 times is not feasible, and doing it manually means no personalisation, a high chance of errors, and several hours of work. What you need is one campaign, to the full list, with each message addressed to the right person.

Most businesses with a client list of 200 or more hit the same wall every festival season. The intent is there. The message is ready. The execution is the problem.

WhatsApp broadcast caps at 256 contacts. If your list is larger, the native broadcast feature is not an option. You would need to split your list, create multiple broadcast groups, and manage separate sends. The process is manual, slow, and easy to get wrong.

Recipients must have your number saved for the broadcast to deliver. If even a portion of your client list has not saved your number, those contacts will not receive the message through the native broadcast. You would not know who received it and who did not.

Copy-pasting does not personalise. Manually copying a message and sending it one chat at a time means every message is identical. No client name at the start. No variation. The message looks exactly like what it is: a mass send.

It takes hours. Sending 400 individual messages manually takes the better part of a working day. That is not a Diwali communication strategy. It is a workaround.

• Your client list in Excel format, with a phone number column (including country code) and a name column.
• A Diwali message template with {{name}} at the opening (use any template from our Diwali wishes messages for clients guide).
• A browser on any device: desktop, laptop, or mobile.
• A WhatsApp account connected to the phone number you communicate with clients from.

The steps below use Roklo. For a broader overview of how bulk WhatsApp sends work, see our complete guide on how to send bulk WhatsApp messages.

Step 1: Open Roklo and Connect Your WhatsApp

Go to app.roklo.ai in your browser. On first use, click "Sync your WA" in the bottom-left corner. A QR code appears on screen. Open WhatsApp on your phone, go to Settings, and tap "Linked Devices." Scan the QR code. Your session connects in under a minute. Your existing WhatsApp contacts load into the dashboard automatically.

Step 2: Import Your Full Client List

For clients already in your WhatsApp, they appear in the Contacts dashboard after syncing. For clients not in your WhatsApp, click "Import Excel" in the top-right corner of the Contacts dashboard. Upload your Excel file. Roklo maps the phone number and name columns automatically. Your complete client list is now visible in one place, with name, phone number, and connection type for each contact.

Step 3: Create a Diwali Group

Go to Groups in the left sidebar. Click "+ Create Group." Name it "Diwali 2026" or a similar label. Add the contacts you want to include in this campaign. You can segment by client type if you have industry-specific templates ready — one group for real estate clients, one for salon clients, and so on. For a single generic greeting, one group with your full list works.

Step 4: Set Up Your Diwali Message Template

Go to Templates in the left sidebar. Click "New Template." Name the template (e.g. "Diwali 2026 Generic"). Write your Diwali message in the Compose Message box. Start with {{name}} so each client's first name appears at the opening. Replace [Business Name] with your own. The live preview shows exactly how the message will look to the recipient. Save the template.

Step 5: Create a Campaign and Schedule It

Go to Campaigns and click "+ New Campaign." In Step 1, name the campaign and select your Diwali template. In Step 2, select your Diwali group as the target audience. In Step 3, choose "Schedule for Later," pick your send date and time, and click "Schedule Campaign." Roklo manages delivery at the scheduled time with message intervals handled automatically. You do not need to be logged in when the campaign goes out.

Copy any of these directly into your Roklo template. Replace [Business Name] with your own.

WhatsApp does not ban accounts for sending Diwali greetings. It flags accounts for behavioural patterns: sudden volume spikes on new numbers, messages to contacts who do not recognise the sender, and spam reports. For the full breakdown of ban triggers and how to avoid them, see our guide on sending bulk WhatsApp messages without getting banned.

• New numbers (under one month old) should stay under 100 messages per day. Ramp up gradually before a high-volume festive send.
• Contacts who do not recognise your number are a risk. Diwali campaigns work best with your existing client list, not with cold contacts or purchased lists.
• WhatsApp's native broadcast list caps at 256. For larger lists, a browser-based tool is the only path that removes that limit.
• Identical messages sent to very large lists without any variation can trigger flags. Using {{name}} for personalisation is the simplest way to add variation at scale.

Send two to three days before Diwali

Diwali morning means hundreds of festival messages arriving at the same time. Two to three days before gives your message its own moment. Clients who receive the greeting early also have time to respond before the celebrations begin.

Keep the message to three to four lines

Clients are busy in the days leading up to Diwali. A short, warm message is more likely to be read fully than a long one. Three to four lines with a clear sign-off is enough.

Send the greeting and any offer in separate messages

A Diwali message that wishes a client well and immediately follows with a discount code reads as a promotional send in a festive disguise. If you have a Diwali offer to run, send the greeting first. Wait two to three days, then send the offer as a separate campaign.

Always include an opt-out line

Add "Reply STOP to unsubscribe" at the end of every message. A client who opts out cleanly is one fewer potential spam report. During a high-volume period like Diwali, opt-out lines matter more than usual because the frequency of messages across all senders is higher.

Test on a small group before the full send

Before running the campaign to your entire client list, test it on a group of 10 to 15 contacts. Check that the {{name}} variable is pulling correctly, that the message preview looks right, and that the send time is confirmed. A two-minute test saves a full-list mistake.

Sending Diwali wishes to every client on your list is one of the highest-goodwill actions a business can take in the year. The impact is not measurable in a single send, but it compounds. Clients who feel remembered during the festival are the ones who come back after it.

The process does not have to be manual. Import your list, pick a template, create a group, schedule the campaign, and Roklo delivers every message at the right time with the right name. The entire setup takes under 10 minutes.

Roklo is a free bulk message sender. Open your browser, sync your contacts, and your Diwali campaign is live in minutes. No API. No download. No saved contacts needed on the recipient's end.
