Write your ideal customer in one line: industry, city, company size and the person you want to reach. “Pharma packaging buyers in Pune” is useful. “Businesses in Maharashtra” is not.

Don’t start with the biggest file. Start with the segment closest to your buyer. A full 2.33 Lac Maharashtra companies list covers all trades.

Remove duplicates and rows without a phone or email. Then filter by city and product, and break the list into batches of 200 to 300 contacts. Small batches let you write a message that feels personal.

Calling works for high-value products. Email suits catalogues and price lists. WhatsApp is quick and informal for small business owners. Pick one or two, not all four. Before you start, check the current rules on commercial calls, SMS and data protection, including DND.

Mention their city or industry, say what you offer in one line, and make the next step easy, like “Can I share a catalogue on WhatsApp?” Talk about their problem, not your company history.

Most people don’t reply the first time. Follow up after three to five days with a different angle. For each batch, note contacts reached, replies and orders. After a few batches, you will see what works.
