The use of IP in email marketing is very important because it can determine the domain's reputation. This domain reputation also determines which section the email server will place the email you send. If you have a bad domain reputation, the emails you send will go to the spam folder. Whereas if you have a good domain reputation, the emails sent will go to the main inbox.
Here is what you need to know about using Shared IP and Dedicated IP when sending email marketing:
Shared IP
A Shared IP is an IP used jointly by many users with one IP. This is why if one user abuses the IP and other users are affected, you can also suffer the consequences. It can be said that the domain reputation cannot be controlled individually because one IP is used by many people.
But on the other hand, Shared IP is suitable for businesses that may have few contacts and do not send emails frequently, so Shared IP is a suitable choice.
Dedicated IP
A Dedicated IP is a unique IP that only you can use personally, so you have broader access to your own IP. Thus, you will have more freedom to control and monitor the domain's reputation. Therefore, you don't have to worry about your domain reputation. As long as you use it properly, there will be no issues with your domain reputation.
If you can consistently send emails for a year, like 100 thousand emails per year, then choosing a Dedicated IP is the right choice. You also need to create a more consistent email sending pattern to build a solid domain reputation.
