They are a largely legitimate bulk mailer that offers their services
to business customers. They aren't always able to weed out customers
with dirty contact lists preëmptively. So some of their traffic is
spam, but IIRC they drop and/or reeducate spamming customers. YMMV.
I'd remove the rule and watch for unwanted traffic. Report any abuse
you find to constantcontact, and see whether their response is adequate.
