Improve Your Email Program Instead of Focusing on Social

Best Practices

Here’s the deal: email continues to outperform social media when it comes to customer engagement, and it doesn’t look like that’s going to stop anytime soon. According to the Radicati Group, there are more than 100 billion wanted emails sent everyday… and that number is expected to rise: According to Forrester Research, user interactions with companies on social websites peaks with Instagram at 4.21%, followed by Facebook at .07%, and Twitter at .03%. Those numbers only represent interactions, and they don’t necessarily mean that viewers took the next step to visit their website. Email, on the other hand, gets much more interaction.

Spam as Overcommunication: Preventing Unsubscribes and False Spam Reports

Best Practices
spam as overcommunication

As you continue to innovate your app, it’s easy to want to reach out and update your customers about your innovations as much as possible. Unfortunately, this can be a mistake. When you communicate too often with your recipient list, you can dilute the importance of your messages and annoy your recipients because you’re flooding their inboxes with information that may not be relevant to them. This frustration from over communication often leads to recipients re-thinking their subscription or even flagging you as a spammer. While you may only want to inform your list, recipients may not want all those emails. This can cause spikes in unsubscribes and spam reports.
