A dedicated IP is an IP address used only by your business, giving you full control over your email reputation and ensuring higher deliverability. For example, if you send invoices or newsletters in bulk, your emails won’t be affected by anyone else’s activity. A shared IP, meanwhile, is used by many users. It is cheaper, but if another user sends spam, the whole IP could be flagged and even your legitimate emails might end up in the spam folder.
