How To Best Follow Up A Submission With A Publisher

What's the best way to follow up a submission?

It can take a long time for a manuscript to be read by a publisher. It can take a couple months, it can even take longer, and an author has to always remember that there are thousands of people trying to be published at the same time as you. It's quite important not to badger a publisher, but a follow-up would be to ring the assistant and to ask what the status of the manuscript is, whether it's been read yet or not. Of course, if you have an agent, which you should have, the agent would be doing that.
