MisarMailQuick Answer
An IP address used by multiple email senders, common with entry-level email service providers.
Shared IPs are used by multiple customers sending from the same ESP. Your reputation is influenced by other senders on the same IP pool — if a co-tenant has high spam complaints, it affects all shared-IP senders. Shared IPs are fine for new senders with small lists; dedicated IPs are recommended once you send consistently at 50K+ emails/month. MisarMail manages shared IP pools with automatic reputation monitoring and high-risk sender isolation.
