We are trained as children (and even sometimes as adults) to learn from our mistakes. Making a mistake is human, but failing to recognize the mistake and learn how to avoid it in the future can be disastrous. This is especially true for e-mail marketers.

 Mistakes come in all shapes and sizes, but here are a few that we see too often.

Don’t wait until New Year’s to make a resolution to avoid these mistakes. Resolve to do better today.
