Hi @MasPega,
The scenario you have described can be achieved. To send Whatsapp messages via Make, you will need to have a Whatsapp Business Cloud and Facebook Business accounts. You can find more information about that here - https://www.make.com/en/help/app/whatsapp-business-cloud. There are alternatives if you don’t with obvious additional costs for using alternative services.
We are automation workflow specialists with extensive experience in dealing with PDFs and sending emails and messages to segregated contacts.
We would like to assist you with setting up your scenario. Please feel free to reach out to us via our website - Contact Us - Siliceous Solutions - World Class Support or schedule an appointment for an initial consultation here - Increase Productivity with Workflow Automation by Siliceous Solutions.
Regards,
Pam.
