Firstly, acknowledge that you may be perceived as rude
Sending a one-line email with your CV, to a bunch of people at the same time, who haven't asked for it can come across as pushy and annoying even if you had previous contact with them. At the very least, you'll want to write more personal emails and take a more humble tone. You want these people to do something for you, so some pleasantries are in order.
Secondly, remember that recruiters don't always have jobs for every CV.
Recruiters work for companies on the basis of job openings, to which they try to match candidates. As a candidate, you can contact a recruiter to see if they have anything for you, but if they don't have anything for which you are a good fit there are only two things they can do:
If your CV looks like something they will receive a job opening for in the future, they can tell you so and keep your CV on file for when something comes up.
If your CV doesn't match the profiles they usually work with or there is some other reason why they don't think they would be able to work with you, they'll send you a rejection.
Sending more emails after the initial contact, even to send an updated CV, will not change reality: either they have an opening that suits your profile or they do not. For this reason, any further contact is at best meaningless and at worst counterproductive.
I say counterproductive, because repeatedly contacting someone without (in their eyes) a good reason will make you look desperate and the fact that you don't realize that they cannot help you at the time can make you look unprofessional. This means they will be less likely to think of your CV when a matching opportunity does come up.
So when can you follow up?
Generally speaking, you should only follow up if something drastic has changed. For instance, it might be a good idea to let a recruiter know that you've found a job already. It also might be a good idea to contact them if you've achieved something that makes your profile more interesting, like obtaining a major certification in your field. If they've made you a concrete promise like "I'll propose your profile to a few of my clients" then after a week or so without any news, you might call them up for a friendly inquiry into the status of the proposals.
Outside of that, you should probably just leave them alone. You're in their database and your profile will come up when they have a suitable opportunity. There's nothing more they can do for you.
