Whatsapp - how to send a message to each member of a group?

Question

whatsapp

Good evening!
There is a Whatsapp chat, about 200 people (I am one of the admins, of these 200 I have only a small part in my contacts, respectively, the rest of the contacts do not have me mutually, plus people can add or leave the group and I don’t I follow). I need to get their opinion on some issue, and since there is quite a lot of garbage in the chat and many just scroll through without reading, I want to send a message with a survey to everyone.

For Whatsapp, I found several services like Voliz and Pollie, but there you can send a message with a question and answers only using standard Whatsapp tools, that is, manually select contacts (200 people) or send to a group (where only a few people will notice it and the messages will quickly go up ) send the messages they generated with the question and links to the answer options to each member of the group ?

Those. you need
1) a service / application for mass mailing of individual messages for Whatsapp. You also need to be able to insert formatted text and links into the message,

or better yet

2) a survey service / application that allows you to send an individual mailing to group members or a list of phone numbers

Answer 1

Well, in general, what you are talking about can be considered a mass mailing of messages, and Whatsapp usually bans for this. Here everything is described in detail by WhatsApp Legal Info. You can create something like a channel in Whatsapp, like in a cart, whatsapp calls it Broadcast like, try this option, it works for a group of up to 200 people in my opinion. And you can also connect the official API business with Whatsapp, but it is still very expensive and you need to develop and approve letter templates there in order to be able to do this. In general, it is not particularly suitable for simple tasks; in principle, it is the most suitable for medium and large businesses.
Well, now, how can you do it differently and a little less formally. There are various whatsapp APIs that provide the ability to automate the work with the messenger, and with the help of them, after spending 5-10 minutes studying the documentation, you can create mailings, within reasonable limits, of course, otherwise you will be banned. Here is a cool article on Habré that tells how to behave properly on whatsapp in order to do your business and not be blocked https://habr.com/en/post/515096/ .
It remains to choose an API, there are probably 5-10 normal ones in total. I worked only with world ones, such as APIWHA, it was not bad and I did a project for the client. I also made a simple bot through the Chat API, there were no problems either.
In general, there are such options, but like all APIs are paid, you need to keep this in mind before you get to work. They cost differently, the price criterion xs, maybe stability and other goodies in the API.

or a business account for money, or spammers with non-guaranteed exchange delivery

Answer 3

Firstly, ™ as a name is somehow not quite suitable. Secondly, the parameters must be separated by an ampersand:
