Application of Proxy IP in EDM Email Marketing｜Enhancement of Delivery Rate

First, why EDM email marketing need proxy IP?

In email marketing.Single IP High Frequency TransmissionIt is the most common "suicidal behavior". Take the real event of a cross-border e-commerce as an example: its marketing team used the same IP to send 2,000 emails per day for 3 consecutive days, and triggered Gmail's spam filtering mechanism on the fourth day, not only did all the subsequent emails go into the spam folder, but also all the historical emails of the original customers were tagged together. This chain reaction directly led to a 37% drop in conversion rate that month.

The underlying logic of proxy IP lies in theDiversification of riskWhen using dynamic residential IP pool, the system of mail service provider will recognize it as "natural behavior of different users". When using dynamic residential IP pool, every 50-100 emails are sent automatically switching IP address, the mail service provider system will be judged as "natural behavior of different users". Measurement data shows that after adopting IP rotation strategy, Hotmail's inbox rate can be increased from 41% to 79%.

Proxy IP to crack the three major pain points of email marketing

Pain Point 1: IP Credibility Collapse
The mail server will rate the IP's reputation (0-100 points), and the rating decays 15-20 points per day when the volume of sends exceeds 300 in a single day. And ipipgo'sDynamic Residential IP PoolOffering 90 million+ real home IPs updated daily, always maintaining a reputation score above the safe threshold of 75.

Pain Point 2: Geographic Matching Bias
Test data shows that: using German IP to send emails to French users, the open rate is only 4.2%; after switching to Paris local IP, the open rate increases to 12.8%. ipipgo supportCity-level positioningFor example, residential IPs of different cities in Spain, such as Madrid and Barcelona, can be accurately called.

Pain Point 3: Send Link Tracking
An educational organization had suffered a malicious report from a competitor due to an exposed mail server IP.

Five, EDM practitioners must know the three core issues

Q: How do I calculate the number of IPs required?
A: Recommended formula: total number of IP = average daily sending volume ÷ 50 (insurance factor). For example, you need to prepare 60 IPs for daily sending of 3,000 packets. ipipgo supports real-time deployment of resources by API.

Q: Will emails with the same content be blocked?
A: Cooperation requiredContent dynamic variables(e.g. address/product recommendation bit), while using ipipgo's smart IP rotation, the same content can be re-sent up to 5 times.

Q: Does the free proxy IP work?
