Jim how do you tell if you are a spammer?

If people click “mark as spam” on your email, you are a spammer as far as that person is concerned. Spam is in the eye of the beholder.

How Spam Filters Work

  • Before we give you tips on how to avoid spam filters we should talk about how they work.
  • How does gmail know a spam message from a real one?
  • First it looks at the outside of the envelope trying to answer the question “do I trust the sender”
    • Is the senders domain reputable?
    • Is the sender’s server IP address in a bad neighborhood?
    • Has this person opened or responded to emails from this sender before?
    • Is the sender’s address in the address book?
  • Second it reads the email to see if  looks like spam.
    • Is the HTML clean?
    • Is it one big image?
    • Is there a plain text copy?
    • Does it smell like spam?
