How do I start using the increased sending limits: Set up your campaign as you normally do. Go to your accounts section and increase your daily connection limits to your desired number.
What are your recommended usage guidelines: Though you can send up to 100 connection requests per day, we recommend sending about 70-80 per week. Please read this article for detailed usage guidelines.
How are you able to bypass LinkedIn limits: Our dev team have found a method to bypass the limits and yet keep your LinkedIn account safe. Our solution does not depend on “the invite by email” feature recently withdrawn by LinkedIn or "gmail/outlook invite" feature.
Do I need a LinkedIn premium subscription to use the higher sending limits: No. Our solution works great with basic LinkedIn and Sales Navigator subscriptions.
Is it safe: We have been testing it from more than a month now and can tell you that LinkedIn can not detect that your account is sending a large number of invites. In other words, your account will not get restricted due to sending more connection requests.
At the same time, using an automation tool is one part of the equation and how you use the automation is another part. Your account can still get detected by LinkedIn if you engage in excessive and irrational usage. You should therefore take general precautions. You can maybe start increasing the sending limits gradually and test for yourself.
