Creciendo Alcance is a free Chrome plugin developed by escuderohuillcamasccoevaristo that allows users to send WhatsApp messages to multiple contacts.

This user-friendly plugin also offers features like downloading group contacts, delivery reports, custom time delays between messages, real-time updates and previews, message formatting with bold, italic, strikethrough, and emojis, and the ability to send multiple links to customers for direct offers. It also provides an auto responder, the option to sync contacts from a cloud server, and enhancements such as downloading and saving unsaved contacts, filtering non-WhatsApp numbers, and auto reply functionalities.
