What is a Source IP Address in Email Marketing?
A source IP address is the numerical label assigned to each device that sends email messages over the Internet. In the context of
email marketing, it identifies the server from which your emails are sent. This IP address is crucial for various reasons, including email deliverability, sender reputation, and ensuring compliance with
anti-spam laws.
Different Types of IP Addresses
There are primarily two types of IP addresses used in email marketing:1. Shared IP Addresses: Multiple senders use the same IP address. This type is usually cheaper and easier to manage but carries the risk of being affected by other senders' bad practices.
2. Dedicated IP Addresses: Exclusively used by a single sender. This allows greater control over your sender reputation and is ideal for high-volume senders.
How to Choose Between Shared and Dedicated IP Addresses?
-
Shared IP Addresses: Suitable for small businesses or those new to email marketing. It is cost-effective and managed by the ESP, but you have less control over the IP's reputation.
-
Dedicated IP Addresses: Ideal for high-volume senders who need better control over their email deliverability. It requires a warm-up process and ongoing management but offers a consistent sending reputation.
What is IP Warming?
IP warming is the process of gradually increasing the volume of emails sent with a new IP address according to a predetermined schedule. This helps to build a positive sending reputation with ISPs. Without proper IP warming, your emails might get flagged as spam, affecting your overall
email deliverability.
How to Monitor IP Reputation?
Monitoring your IP reputation is essential to maintain high deliverability rates. Here are some ways to do it:
-
Reputation Monitoring Tools: Use tools like Sender Score, Google Postmaster Tools, and Microsoft SNDS to track your IP's reputation.
-
Feedback Loops: Sign up for feedback loops with major ISPs to receive notifications when recipients mark your emails as spam.
-
Blacklists: Regularly check if your IP address is listed on any blacklists, and take immediate action if it is.
Best Practices for Managing Source IP Addresses
-
Consistent Sending Practices: Maintain a consistent sending volume and frequency to avoid sudden spikes that can raise red flags.
-
Quality Content: Ensure that your emails offer value and comply with
email marketing best practices.

Authentication Protocols: Implement email authentication protocols like SPF, DKIM, and DMARC to verify your identity and improve your sender reputation.
