Automated InMails
Automated InMail option is available in the Expert UI for Pro and Turbo users within the extension (Options → Actions tab). In addition, Turbo and Cloud users can add an InMail action to a drip campaign sequence.
This article explains how to enable and use the automated InMail feature within the extension, which is especially useful for Pro users. To enable it, go to Dux-Soup Options → Actions tab

and turn on “Send InMail™ during visits using Sales Navigator or Recruiter”.

Next, go to LinkedIn and create a People search by applying preferred filters. Click on the Dux-Soup icon and select Visit Profiles to start sending InMails™.

Dux-Soup will start sending InMails™ to the profile list you have created, using your available InMail™ credits.
You can also send InMails™ to profiles marked as Open, which do not require InMail™ credits.
The process is the same as described above, with the additional step of enabling a skipping rule in Dux-Soup Options → Skipping to skip profiles that are not OpenLink members.

You are typically allocated around 800 OpenLink InMails™ per month.
InMails are messages you can send on LinkedIn to people you’re not connected with. They’re commonly used by recruiters and professionals to reach new contacts when connection requests aren’t suitable.
To use InMail, you need a LinkedIn Premium account (Business, Sales Navigator, Recruiter), which includes a monthly allowance of InMail™ credits based on your subscription.
Note: InMail™ credits must be purchased through LinkedIn - Dux-Soup does not sell InMail™ credits.
