Clerk Chat review

Clerk Chat is the cheapest way here to add a team texting inbox to numbers a business already owns. Growth is listed at $9.99 per user per month and Ultimate at $19.99, with a $60 saving a year shown for yearly billing. Both include messages described as unlimited, subject to terms, and Growth covers up to 8,000 contacts while Ultimate raises that to 50,000 and adds message campaigns. The app connects to existing numbers from Microsoft Calling Plans, Twilio and Telnyx, so there is no need to port or change carriers, and it is a Microsoft 365 Certified app that runs inside Teams. The shared inbox includes group messaging, internal threads, templates, variables, a blocklist and round-robin assignment. The low base price rises with add-ons: HubSpot, Salesforce and Microsoft Dynamics each cost $15 per seat per month, log exports $5 per seat, and a 48-hour 10DLC rush is $500.
