Before you worry about templates, timing, or tone, the first step is simply getting your customer numbers into a broadcast tool. For most Indian business owners, this means exporting a list of numbers that currently live in one of three places: a physical register, a Google Sheet or Excel file, or saved directly on a phone.

**Step 1: Prepare your contact list.** Create a CSV file with at least two columns: Name and Phone Number. Phone numbers should include the country code (+91 for India). If you have purchase history or last visit dates, include those too — they are useful for segmentation later. Remove any duplicates and blank rows.

**Step 2: Upload to Liliya.** In Liliya's Contacts section, click Import → Upload CSV. The platform validates each number, checks format, and flags any that cannot receive WhatsApp messages. This takes 2–5 minutes depending on list size.

**Step 3: Create your first broadcast.** Go to Broadcasts → New Campaign. Select your imported contact list (or a segment of it). Choose an approved message template or write a new one. Liliya's template library includes ready-made options for common use cases. For your first campaign, keep it simple — a warm re-introduction and a reason to come back.

**Step 4: Preview and send.** Send a test message to your own number first. When you are happy, schedule or send immediately. Liliya delivers messages in batches to stay within Meta's daily limits. For most first-time campaigns, you will see replies within the first 30 minutes.
