I haven&#x27;t used SES, but I&#x27;m guessing it is complex, and &quot;bare bones&quot;.<p>I got the vibe Mandrill didn&#x27;t want to send any business to their _actual_ competitors.<p>The time period to make this change sucks. I accept they want to change, and they can do that. But I have paid them money for a service, and the rug is being pulled from under my feet with such a short period of time to work out what to do, and do it.
