IP reputation
IP reputation is the part of sender reputation tied to the IP address of the server that delivers your email.
How it affects cold email
If you send through Google Workspace or Microsoft 365, your mail goes out on IPs the provider runs and shares across many customers, so you can’t change their reputation much on your own. Your domain and mailbox reputation carry more weight.
If you run your own server or use a dedicated IP, you own that reputation completely, including the need for a valid PTR record and a slow ramp-up.
How Inboxed handles it
- Campaign emails leave from your mailbox provider’s servers, not from Inboxed IPs, so they carry your provider’s IP reputation.
