WBizTool has been a great tool to fill a missing piece in our workflows. We are able to send out WhatsApp messages to warm up our old customer base using regular WhatsApp numbers - not having to go through the Meta applications. This does mean you have to keep message limits in mind, so be aware of that- less than 500 a day is best practice, as well as follow some other guidelines / bets practices. That means mass cold messaging is probably going to get you blocked. But as part of marketing workflows like we use it for- it's really reliable! I have also been able to successfully place API calls to allow messaging as part of Pabbly Connect workflows in our eCommerce site too. Plus I have used the service for non-profit use where I have messaged reminders and attachments to participants about events. There are features that have been added since I purchased that I haven't explored yet. This is definitely a great platform and a great LTD. Oh and customer service has been helpful and responsive!
