Quick and straight to the point. People are too busy to open emails, so expecting them to read long messages is a far-fetched idea.
In email marketing, emails should be short and start with acknowledging a recipient’s problem or diving right into the purpose so the reader does not have to waste their time.
After a catchy introduction, transition to a supporting copy, but do not deviate from the main point of the email.
Writing an effective marketing email that is also short is difficult. Take the time you need to fine-tune your copies and do some A/B testing to see what works and what does not.
