Will a Sales Insight email be send if unsubscribed?

Emails can still be sent via the Outlook add-in as it uses a different system than the one in SFDC.

Depending on what content you're sharing, if the email is set up as an "Operational email" it should bypass the subscription/unsubscribe option, and will send to everyone (those who are blacklisted, etc.).... though as a best practice, emails are only developed and deemed "Operational" when they're a necessary and important communication with that person about their record, etc. (they're not used for standard sales/marketing communication.)

I do not know if this has changed, but I have had issues with Operational Mails still not being sent to people who are unsubscribed. This was a long time ago.

However, I think that outbout MSI mailers should go out on a seperate, designated IP, as we have had a lot of problems with our sales stuff sending out mailers via MSI that never reach the clients Inbox due to spam filter issues. (I suggested an idea to this effect, but I don't think it got enough votes.)

Keith, please provide the url of your idea. I'll vote for it. I have the same problem that the email from our sales get bounced too as some of the mail server's are constantly blocked due to spamcop.

Today, I ran into the issue again where several leads who unsubscribed registered for an event through our website. But the approval/conformation email sent from Sales Insight in Salesforce is NOT sent, even though it's set to be an operation email.

Diederik,

Looks like I owe you an URL here goes:

One of the things I have done to help mitigate the issue is to create an alert every time someone who is unsubscribed registers for an event. The alert notifies the relevant sales team members that one of their contacts/leads registered for an event, but might not get the confirmation information.

Awesome idea Keith!
