How to suppress trackers from e-mails (campaign)

[caps-entreprise]

Hi,

Sugar automatically inserts trackers when we send e-mails with campaign module (such as the opted out tracker).

I know how to delete an opted-out tracker thanks to the HTML editor, but it seems that one tracker remains:

The line of code in the e-mail is starts by <p>&nbsp;</p><br><IMG HEIGHT=3D'1' WIDTH=3D'1' src=3D'
followed by the address of our sugar server.

It doen'st appear in the source code of the template but it appears in the source code of the message that is received by our contacts.

Does anyone know how to be sure that no tracker will remain? Is there an option to prevent this?

Thanking you in advance for your help,

Best regards,

Ewen

It's just simple.
In the campaign you have to create an optout tracker and in the email template you simply do not use this tracker.
