I’m not sure if I understand your need though, inserting [_url] into the mail body might help. See the doc for detail.
Special Mail Tags
Heh sorry about not being clear enough. I meant the id of the form instance, or submission.
Every submission gets an ID in the database of CF7, so I would like to include that ID in the outgoing emails.
So for instance, when I make the first submission, I would get an email that informs me my message has an ID number 1.
The plugin Contact Form to DB Extension clearly outputs all submissions in a table, so I guess there should be a way to output some form of an ID.
Basically, keeping track of all submissions – if the person in charge gets, for instance emails with submissions 123467, then he/she automatically knows something’s wrong since the submission 5 wasn’t delivered.
…”database of CF7″ The database is not CF7 it is part of that plugin.
Perhaps try the Contact Form to DB Extension plugin forum.

But this probably means that the mail was send already and you may want to do something in-between ?!
