hello tomas,

as far as i know, unfortunately there is no setting to disable tracking in the mass_mailing​ module. i’ve just created the mass_mailing_disable_tracking​ module for this. i cannot post a direct link to it because this forum tells me that i don’t have enough “karma” 🙄 (and it punished me by forcing me to retype this whole message), but you should find it on github: it’s OCA/social#1681. feel free to try it out, review or comment.

kind regards,

hugues de keyzer
