I exported a list of users from Intercom and I'd like to connect with them via Linkedin. I setup a zap via Zapier to do it automatically moving forward but I haven't found an easy way to add the initial group other than manually via gmail + Rapportive.
If I am not mistaken, You want to add people based on the email addresses you have.
If that's the case, its really simple. Go to add connection>Click any email option> select Invite by individual email option and paste the emails you have.
Via this, the invite would be sent to these people but it depends on them whether they want to get connected with you or not.
I can also help with programming the entire stuff and for that matter, find relevant contacts from LinkedIn based on your criteria.
Feel free to reach out to me.
