What is a spam filter?

If you're asking yourself "What is a spam filter?" you've come to the right place.

A spam filter is software that uses various techniques to redirect unwanted email away from a user's inbox. These filters can be based on a variety of criteria, including a sender's email address; specific words in the subject or message body, and can be implemented by end-users as well as ISPs. Spam filtering can occur at the email program level, or occur at the email server level and filter email before it is received to an inbox or spam folder.

We recommend using a spam-checking tool to analyze your message content before you send your email campaign to try and get the lowest possible score. Generally, the higher the message scores in a spam checking test, the more likely it will be filtered to a contact's spam folder.

How can you avoid spam filters?

There are several best practices you can pay attention to in order to avoid being caught by a spam filter. For example:

1. Follow best practice email marketing techniques.

2. Have permission to contact the recipient. If you don't you are spamming.

3. Avoid spam trigger words in your subject line.

4. Use a consistent "From" field.

5. Monitor blacklists using a blacklist monitor.
