MailBluster secured and reputable IP addresses are not directly provided by the platform itself. Instead, MailBluster uses SMTP provider to send all marketing emails. Because of this setup, the IP reputation and security are fully managed by SMTP provider, which ensures reliability.
If you require a dedicated IP or SMTP server for your campaigns, you need to configure it in your own SMTP account. MailBluster does not require any extra setup from its side. Once you purchase a dedicated IP, MailBluster can use it. Otherwise, your campaigns will use the shared IPs.
