Can I upload client numbers via Excel in Heyo for a WhatsApp campaign?

⚡Quick answer

Yes. Heyo lets you run bulk WhatsApp campaigns by uploading a CSV or Excel (.xlsx) file that contains exactly two columns—name and contacts. After you upload the file, Heyo automatically fetches the data and sends the campaign messages to each contact.
