On Wednesday afternoon, we suddenly started seeing signficiant delays on a mission critical and time sensitive marketing email we send out every day. Support has suggested that it can take up to an hour to send emails. (This only goes to less than 1000 subscribers.) Historically it has taken only a few minutes and we've never experienced this delays, but since Wednesday it seems to only be getting worse. Is anyone else experiencing something simliar now or had a similar experience in the past?
