How to exclude certain users from emails?

Hi,

This might sound strange, but I need to find a way to exclude certain users from any and all (!) system-generated emails being sent.
Maybe it's simple, but for now I'm struggling... so, thanks for some help, or at least pointers in the right direction.

So, I'm thinking to have a single checkbox CB profile field, like cb_no_emails.

I looked at Auto Action to see if I could prevent emails being sent if a condition is "[cb_no_emails] equal to 1".

For triggers the following read suitable:
- onBeforeEmailUser
- onBeforeSendEmailMSG
- onBeforeSendEmail
- onCPayBeforeMailerEmailMessageSent

If Auto Action is the way to go, then I'll probably need to use type Query to update/set some field(s) somewhere...

Leads to these questions:
1.) Is this generally possible with Auto Action and updating certain DB fields, or would it require hacking PHP?
2.) If AA, which triggers to use, and which tables/fields to aim at with the query?

Many thanks in advance for the briefest reply!


P.S.:
Thinking about it, it could maybe be a future option in CB Privacy to let users decide if they want to continue getting mails or not. There are quite a few people out there who want to be part of something (like a community) but not be bothered by more or less frequent emails.
Take it as a feature request?

CB is not a newsletter extension. Opt-out of system emails is not and will not be possible. Eventually CB Notifications (possibly built into CB, unsure at this time) will be developed to allow opt-in/out of site notifications (GJ already allows this for its notifications).

There's no way to globally turn off emails per user. The triggers associated with the mailer won't allow this to function unless you error the mailer, but doing so will likely throw an error anywhere the mailer is required.

What emails exactly are you trying to exclude them from?

Thanks again for your reply and the explanations.

It's mostly, if not all, the mails related to CBSubs: on plan activation/renewal/expiration (incl advance reminders)/deactivation, etc.

Should I maybe consider using usergroups to separate those users who must be excluded, and then not use the mails in CBSubs' general settings or per plan, but instead for each and everything the separate "CBSubs Mailer" plugin, in which I can set the usergroups? Looks like a viable workaround to me... what do you say?

Best I can suggest is replace those emails with CBSubs Mailer usages (you'll need to run the mailer queue daily with CRON) and have it condition against your field to allow them to exclude themselves from such emails. However, those are system emails and really shouldn't allow opt-out.

Thanks Kyle,

I'll see what'll take less time and effort: setting it all up in Mailer or convincing the client... :dry:

Another solution would be to just add a new CB opt-out field (check box field) and configure your mailers to not send if people have checked this field.
