I have 38k phone/WhatsApp numbers of a specific group, how to contact without paying for each message?

[ThinkWar]

I bought a list of phone numbers of potential customers from various countries. As I plan to use Whatsapp for outreach, I discovered that Whatsapp for business charges exorbitant amounts per message, making it unpractical to contact everyone on the list using their platform.

Are there alternative solutions that I'm unaware of? Thank you in advance for your help

Contemplate connecting with customers through SMS or Telegram.

The availability of potential SMS marketers interested in purchasing or entering a revenue-sharing arrangement for the phone numbers you collected depends on the manner in which you obtained the numbers and whether or not you acquired proper consent.
