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.
I've had to do a lot of contact list manipulation and I feel your pain.
I would go after this in two steps.
1. Upload these 200 contacts to your email client.
2. Use Linkedin add contacts tool as see in the link below.
1.You might need to add a special notation in your spreadsheet to make these contacts appear before all your other contacts
2. You may want to look at one of your under utilized email accounts and add the contacts there.
Feel free to setup a call if you have any additional questions.
