Do you receive any emails from sales professionals? Do they read something like this?
"I want to personally invite you to schedule a live demo..."
"I saw you on LinkedIn and thought you might find our new web series helpful."
"I'm not sure if you are the right person to discuss this at your college, but..."
Who do you think those emails are for? Are they for you? Or are they for the sales person?
Sure, your name and email address are in the, "To," line of the message, but are any of those messages personally for you? You know what my answer is, don't you?
Of course they're not for you. Those emails are for the selfish sales person who sent them. A little sales prospecting never hurt anyone, right? 
How successful do you think those emails are? I could say, "not very," but I would not be adequately explaining how useless they really are.
The purpose of email is to generate two-way conversation; not to push, push, push "stuff" into your prospect's inbox.
And that brings me to my point. Have you taken a hard look at your enrollment and admissions emails recently? Go back in your CRM, and look at any automated templates. If you don't have the technology, look at the emails you composed and sent through Gmail and Outlook.
Have you "personally invited" anyone to an Open House recently? If so, how personal was your invite? If you aren't sure, then let me remind you of those 4 terms I suggested you should avoid in your emails. I wrote about them a few months back.
Your prospect doesn't want a mass email inviting her to an event. She wants an email that specifically tells her why your event is so IMPORTANT for HER to attend.
Those are the messages prospects will act on. To make them effective, though, there is some information you need. Primarily, you must know and understand why she NEEDS to attend this specific event. If you don't know why then you can't specifically tell her why, and you are losing an opportunity to engage her. If you don't know why it's important to her, then your personal invitation isn't so personal after all. in fact, it's just as cold as those sales emails we discussed above.
Think you could improve your emails? A year or so ago, I created an email checklist that can help you get started.
