Send a massive messages

[jhonattanvargas]

Hi, I'm creating a bot to send mass notifications to my users. I think the maximum number of users I will send the information to is around 800. I was planning to do it with the following code:

users.map( user => { venomClient.sendFile( user, pdfPath, filename, messageSend ) })

Do you think I will have any problems when trying to send the messages?

Anyway, once it's implemented, I'll let you know how it's working.

You will 100% be banned doing that.

Perhaps I explained myself poorly and it sounds like my intention was to spam, but the way my notifications work is as follows:

• First, I generate an ID for the users using the telephone information I have stored in my database.

• Then, they must voluntarily send me a message to the bot to subscribe to the automatic notifications.

• When I want to send a message to all users, such as "this Friday is the last day to take X action," it will only be sent to users who decided to subscribe voluntarily earlier.

Also, it's worth noting that the user can cancel their notification subscription at any time.

Well, intention doesn't matter. You may think that if the user sends a message to your bot first, then WhatsApp wouldn't count them as spam, but you will very likely still be banned.

Because that's what I did, and I only sent a message to 3 people. Same as what you're planning to do. In your case, you're sending a shitload more.

Probably adding a random delay between contacts could reduce the likelihood of getting banned, but it's not guaranteed.

I understand what you're telling me, thank you for the information, but I have a question, would I be banned from WhatsApp in this case?

[amirasyraf]

Probably will, probably will not.

Like I mentioned, add a random delay between messages. The longer the better.

Also, try to vary your messages, maybe add some randomly generated string at the end.

The goal here is to make it less obvious that you are a bot.

I suggest you create sending groups too, I'll tell you the strategy I use and I send 1200 to 1500 contacts, but as the friend said nothing is guaranteed, but understand, the longer the interval between sending messages, the lower the risk, the faster to send, it will almost certainly be blocked.

1- I put an interval between 7 and 12 seconds between each message.
2- I put the person's name in the message, this makes the message personalized, if you don't have the name I suggest you have 3 or 4 text variations, then you change it.
3- I send in groups, every 17 or 20 messages I put a break of 3 to 5 minutes, the longer the time here the better, calculate based on your contacts, but keep in mind, the slower the lower the risk.
4- Within this group of messages I have some numbers that I always keep in touch with, we exchange a lot of messages, so I send a random message to these people, that is, send about 5 or 6 messages and in the middle send a message to a contact who If you have a lot of interaction, I suggest putting 3 of these numbers that have a large history of conversations, this is important for Whatsapp.

Understand that none of this is guaranteed, but it makes it difficult for whats to classify you as a bot.

Hope this helps.

@andpeicunha in your case, theses messages are for people that have you added as a contact or not?
