Cruz M.Professional Independent Marketer
As a marketing professional, I had trouble communicating with my contractors because we used Slack and Teams, but they weren't always online. I spent months looking for a tool to help me send text messages or WhatsApp messages to them so they could log in to Zoom and Google Meets. Plus, Clerk Chat also allows me text my clients that I have on HubSpot CRM.
