Cons
Con Can get expensive quickly
Con Unreasonable anti-spam policy
Not suitable if you have an association with online advertising. A single email that may include your domain that appears on Spamcop will result in a threat to terminate your account and a requirement to disable the URL -- even if you are not responsible for the production or sending of the email.
Con Config changes take 5-10 minutes
Any config change is queued for several minutes before being applied, without any time estimate. Combined with caching and DNS delays, it can make debugging a bit more difficult.
