How to Send WhatsApp Messages from CSV
Required columns, phone number format, opt-in status, and a clean CSV workflow for WhatsApp updates.
CSV keeps bulk WhatsApp work organized
CSV is a simple format for moving contact lists from spreadsheets into business tools. It is useful for WhatsApp reminders because it keeps names, numbers, dates, amounts, and notes in structured columns.
The goal is not to send to as many contacts as possible. The goal is to send the right update to the right opted-in contacts with fewer manual mistakes.
Recommended columns
- name
- phone
- country_code
- consent_status
- message_type
- due_date or appointment_date
- notes
Keep the file simple. If a column does not change the message or help with review, you probably do not need it.
Phone number format
Use one format across the file. Include country codes and avoid spaces or punctuation if your import flow expects clean numbers. Check a few rows manually before upload. Bad formatting creates failed sends and support work later.
If your list comes from Excel, save it as CSV after cleaning names and phone numbers. Read How to Send WhatsApp Messages from Excel if your source file starts there.
Import and schedule
With MessageKro, the practical flow is simple: prepare the CSV, select the list, write the WhatsApp message, choose timing, and review everything before scheduling. Use CSV WhatsApp Sender for CSV-based business updates.
Example: Hi {{name}}, your appointment is confirmed for {{appointment_date}}. Reply here if you need to change the time.
Example: Hi {{name}}, reminder that invoice {{invoice_number}} is due on {{due_date}}. Thank you.
Keep it responsible
CSV lists can make sending easier, so review matters even more. Do not upload purchased lists. Do not message people who do not know your business. Do not keep sending when a customer asks to stop. For larger list workflows, follow WhatsApp Bulk Messaging Best Practices.
