New data has shown that almost half (45% ) of all emails sent are considered spam, meaning many of your email campaigns could be falsely marked as spam. It comes as no surprise that ESPs (Email Service Providers) are constantly having to update their systems to filter these emails into the spam folder, which makes it harder to successfully hit the recipient’s inbox.
What’s more, Spam emails make up 73% of global emails sent, with the United States being the number one country for generating spam emails. Sending frequent emails can help with hitting the recipient’s inbox, but it is imperative to ensure that your emails are relevant to your consumers. Irrelevant emails are more likely to be deleted, marked as spam or remain unopened. This could have a negative impact on your inbox placement. Checking your sender score on a regular basis can help give you an idea as to where your emails will place. Useful tools such as Return Path are an example of where you can check this.
