How to import contacts from CSV or Excel
You can bring your existing customer list into Advertz from a CSV or Excel (.xlsx / .xls) file.
Prepare the file
- One row per contact, with a header row
- A phone column with the country code (for example 91 for India), digits only
- Optional columns: name, email, tags and up to five custom variables you can use in templates
- Download the sample file from the import screen if you are unsure about the format
Import
- Open Marketing → Contacts and choose Import.
- Upload your CSV or Excel file.
- Map each column in your file to an Advertz field (phone, name, email, tags, variables).
- Review the preview and confirm the import.
Duplicate phone numbers are not created twice — each phone number exists once per account. Your plan’s contact limit applies.
Tips
- Only import customers who agreed to hear from you on WhatsApp (opt-in). Messaging people who did not opt in leads to blocks and a lower quality rating.
- Use tags (for example “Diwali-2026” or “Retail”) so you can target campaigns later with Marketing → Segments.
