Email bounce rates can significantly affect your marketing performance, and a high bounce rate often signals poor list quality. There are two types of bounces: soft bounces (temporary issues like a full inbox) and hard bounces (permanent issues like invalid addresses). Cleaning your email list regularly is the first step in reducing bounce rates. Removing inactive or incorrect email addresses can prevent future hard bounces.Additionally, setting up email authentication protocols like DKIM, SPF, and DMARC ensures that your emails are recognized as legitimate by ISPs, improving deliverability. Klaviyo offers built-in tools to help you monitor bounce rates and maintain a clean list, which is essential to ensure your emails land in your customers’ inboxes and not their spam folders.
