104 Email Marketing Myths, Experiments, and Inspiration

104 Email Tips

This email marketing guide was developed with our friends at HubSpot to provide senders with more than 100 ideas for making changes and improvements to their email programs. The guide covers myths, or false assumptions, that many marketers fall victim to, experiments and tests you can implement, and inspirational ideas you may not be using yet.

Here’s a sample:

  • Myth #2 – Unsubscribes are THE WORST – Unsubscribes aren’t bad. In fact, an unsubscribe is simply someone telling you they no longer want your messages. By removing them, you can improve the quality of your list and prevent unengaged recipients from marking your messages as spam.
  • Experiment #52 – Subject line emojis – Emojis are great for some contacts and come across as less professional to others. Test to see what types of subject line characters your contacts prefer to see.
  • Inspiration #97 – Reward your VIPs – Rather than simply testing new campaigns to brand ambassadors and high-engagers, consider giving them a special promotion or offer to thank them for their interest.
