The ZenSourcer browser extension will by default be enabled to also work in Gmail threads where it detects a person who has been sourced using ZenSourcer.
This will allow you to take actions on prospects and candidates from your Gmail inbox, like marking reply status (Interested, Not Interested, or Reach Out Later); converting Prospects to Candidates in Greenhouse; adding a note; adding a reminder to follow-up on a specific date; and adding someone to a new Project or Sequence.
If you prefer not to use the ZenSourcer extension in Gmail, you can disable it in your ZenSourcer Settings by visiting https://www.zensourcer.com/settings
Even with the sidebar auto open in Gmail disabled, you can still choose to manually open or close the sidebar when you are viewing an email thread with a person sourced via ZenSourcer. Just click the ZenSourcer logo in the Chrome toolbar, to the right of the address bar.
