How can I use Mercury for?

Mercury was created to a cheap and simple WhatsApp API provider and messages gateway solution. Mercury was designed to automatically send WhatsApp messages and can therefore be used for WhatsApp marketing and business communication strategies. It could also be very useful for customer support, as in addition to being able to use the same WhatsApp number on multiple devices simultaneously, you can also create WhatsApp autoresponder chatbot. In addition, you can also integrate Mercury directly into other software through our APIs.

Can I use Mercury for massive marketing messages?

We encourage our customers to do not send unsolicited (spam) messages. That being said, you can technically do it, however, please bear in mind that we are not responsible of the abusive usage that violates WhatsApp terms that might eventually ban your WhatsApp account(s). Our system is designed to minimize risk from getting banned by WhatsApp when sending massive messages, but there is an inherit risk that we cannot control when users report you as an spammer. If you send too many unsolicited messages to random users, your account might be banned after a while, since users can manually report your account to WhatsApp as spammer. This may cause your account getting banned. We strongly encourage our customers to send legit messages that users are reasonably expecting to receive.

If my number is banned, what happens?

If your number is banned by WhatsApp you won't be able to use it again. The credit that remains in the account will be intact. You can continue using our system normally linking a new number. Mercury can't guarantee that the numbers won't continue getting banned. It depends on the use you make of our system.

You can add as many numbers as you want. Each WhatsApp number corresponds to an instance of Mercury (exactly how it works for WhatsApp Web). If you want to activate more than one number you will need to activate more than one instance. Alternatively, you can also log out and return to Mercury with another number. The important thing is to remember that each instance of Mercury has one WhatsApp number, but there are no limits to the accounts you can create in Mercury. And remember that thanks to Mercury you can use one WhatsApp number multiple devices.
