An acceptable email bounce rate for your B2B business is generally under 2%. You should aim for a bounce rate lower than this to maintain good email deliverability. A higher bounce rate can indicate issues with your email list such as outdated or invalid email addresses. You can reduce bounce rates by regularly cleaning and verifying your email list. You should also segment your list to target only engaged recipients. A low bounce rate ensures your emails reach the right audience and boosts your sender reputation. Monitoring your bounce rate can help improve the success of your B2B email campaigns.
