How to send 6k mail in one time in linkedin

I think there may be a misunderstanding here!

LinkedIn is a professional networking platform, not an email service provider. It's not possible to send 6,000 emails at once through LinkedIn. In fact, LinkedIn has strict policies against sending unsolicited messages or spamming other users.

If you're looking to send a large number of emails, you may want to consider using a dedicated email service provider like Mailchimp, Constant Contact, or Sendinblue, which offer bulk email sending capabilities.

However, if you're looking to connect with a large number of people on LinkedIn, you can try the following:

  1. Personalize your connections: Instead of sending a mass email, try connecting with people one by one and sending personalized messages or invitations to connect.
  2. Use LinkedIn's messaging feature: You can send individual messages to up to 50 people at a time using LinkedIn's messaging feature. Just be sure to keep your messages professional and relevant.
  3. Join LinkedIn groups: Participate in relevant LinkedIn groups and engage with others by commenting, sharing, and posting valuable content. This can help you build relationships and establish your expertise.
  4. Use LinkedIn's "People You May Know" feature: LinkedIn's algorithm suggests people you may know based on your connections and interests. You can use this feature to find and connect with new people who may be interested in your work or expertise.

Remember to always follow LinkedIn's terms of service and guidelines for using the platform.
