1. Accidental Email Sends to your Competitors?
It is possible to build into the configuration of your Vuture instance a Regular Expression which will limit the email addresses or domains that can be sent to, from your instance.
For example, you may wish to limit your instance to prevent a user from ever sending an email to your competitors. This would be more permanent, and possibly more reliable, than adding individual contacts to a Send No Mailings folder - because individuals can be accidentally removed from a folder and find their way back onto mailing lists.
To do this, you will need to let your AM know the list of competitor email addresses or competitors' domains you would like to automatically exclude from all future mailings, even if they are added to a mailing list.
2. Only Send to a Limited List of Domains?
Another possibility in reverse is to write an instruction into the configuration of your instance, so that only email addresses or domains that match this regular expression will actually be sent.
To do this, you will need to let Support or your AM know the list of email addresses or domains that you would like to be able to send to. This will limit the entire instance so that your users can ONLY send to those email addresses or domains.
Note: This would be applicable to your entire instance and therefore a fairly unusual option to take. Consider discussing with your AM before taking this step.
To Configure Your Regex
Support or your AM will access the configuration page at Admin.System.Emails and write a regular expression into the Restrict Sent Emails Regex field.
Example for Option 1 - exclude competitors and others:
^(?!.*(info@vutu\.re$|[\w-\.]+@vuturevx\.com$))
would allow emails to be sent as normal, but any email to the domain @vuturevx.com or the specific email address info@vutu.re would be silently ignored and not sent.
Example for Option 2 - only send to these domains:
