1. Check your IP and domain against blocklists “When your email content regularly gets delivered to spam traps and honeypot addresses (a symptom of not cleaning your mailing lists), you’re likely to see your IP and domain appear on blocklists.” Getting blocklisted isn’t the end of the world, and not all deny lists will have a serious impact on your delivery rates.

2. As the name suggests, email sender reputation (sometimes referred to as sender reputation) is a score that identifies you as a trusted – or mistrusted – sender. Different mailbox providers use different scores to judge whether to classify your mail as spam. “If you use purchased contact lists, don’t routinely clean your mailing list, or use a webmail address as your sending address, your sender reputation can suffer, and your emails may not reach your recipients’ inboxes.” Sender reputation is also known as domain or IP reputation because – you guessed it – it’s associated with your IP addresses and domain names.
