WhatsApp

WhatsApp is best for SMBs and individuals who need to communicate quickly and securely with customers or teams via messaging. It stands out for its massive user base, end-to-end encryption, and ease of use, but may not be ideal if you require advanced business integrations or deep analytics. Compared to Telegram, Signal, and Slack, it’s better suited for straightforward, real-time conversations, especially where your audience is already active on WhatsApp. If you’re dealing with fragmented communication or need to reach users where they already are, this is probably the right tool. If not, you might want to explore Slack or Microsoft Teams for more robust business features.
