What is IP Reputation?
In the context of 
email marketing, 
IP reputation refers to the trustworthiness of an IP address that is used to send emails. It is a critical factor that determines whether your emails land in the recipient's inbox or get filtered into the spam folder. A good IP reputation indicates that your emails are less likely to be marked as spam, whereas a poor IP reputation can severely impact your email deliverability.
Why is Monitoring IP Reputation Important?
Monitoring your IP reputation is essential because it directly affects your 
email deliverability rates. If your IP reputation deteriorates, your emails may be blocked or sent to the spam folder, reducing the effectiveness of your email marketing campaigns. By keeping an eye on your IP reputation, you can identify and address issues before they negatively impact your business.
    Spam complaints: The number of recipients marking your emails as spam.    
Bounce rates: The frequency of emails that are undeliverable.
    Volume of emails sent: Sending too many emails in a short period can raise red flags.    
Engagement rates: How recipients interact with your emails (opens, clicks, etc.).
    Blacklist status: Whether your IP is listed on any spam blacklists.
