MisarMailQuick Answer
A database of IP addresses or domains known to send spam, used by mailbox providers to block unwanted emails.
Email blacklists (also called blocklists or DNSBLs) are databases maintained by organizations like Spamhaus, SORBS, and Barracuda that list IP addresses and domains with poor sending reputations. Being blacklisted causes emails to be blocked or filtered to spam by receiving mail servers. Common causes: high complaint rates, sending to spam traps, sudden volume spikes, or compromised accounts. MisarMail monitors 50+ major blacklists in real time and alerts you if your sending IP appears.
A score assigned by mailbox providers based on your sending patterns, determining whether your emails reach the inbox.
Spam TrapEmail addresses used by ISPs and blacklist operators to identify senders who don't follow permission-based practices.
Email DeliverabilityThe percentage of emails that reach the recipient's inbox rather than the spam folder or being bounced.
