WA Toolbox by Elbruz Technologies

For the price they charge, it's not worth it. The tool sometimes sends duplicate messages, for those who want to send quickly in groups, they will be disappointed compared to other tools that existed (Promote Route) and that cost 5x less. Google Chrome itself has a blocking functionality for messages with low delay, so if you want high performance, this is not a good option.

The tool is extremely useful for managing groups and for more functions, the only thing I have against it is the support service, I have not had good results, I have had the tool for a long time, and I have always said and will ask for an academy on how to explore more advanced options with webhooks. Keep developing and please give assistance thanks.
