Can we enable communication limits to an individual lead?

Sure. Run a smart list that matches:

1.Email address IS: Whatever your email address of lead(s) is.

and

2. Email is Dilivered (or opened) Email: Is ANY (add constraint) (# of times) 

Flow would of course be to unsubscribe or decrease score *wait a few days* and then remove from that list or increase score again. 

Just my first thought. But like you said. You can of course do this on a global level in your admin setting under Communication Limits.

Hope that helps

You can mimic Communication Limits in the way that Stephen mentioned. You can not use the out-of-the-box Marketo "Communication Limits" function per lead, it only works per Smart Campaign.

THANK YOU.

Hi Debra,

Before communications limits was a feature, I had set it up for a client where I had created a "Emails sent in past 30 days" field which had a type of "score." When they received a non-operational email, add 1 to that score, wait 30 days, subtract 1 from that score. If that score field hit 5+, another campaign set Marketing Suspended to true, and if it dropped to 4 or less, set Marketing Suspended back to false (I would use that field instead of Unsubscribed).

Might be another option, depending on what you're trying to accomplish.
