What is an IP Warm up?
When you’re using a new server IP, this IP isn’t reliable yet on the Internet, and it is likely that the ISP (Internet Service Provider) does not know about the brand new IP.

Thus, IP Warmup is the process of making Your Reputation on the Internet by slowly increasing the number of emails sent using your IP address based on the predetermined timeframe.
When Internet Service Providers detect that an email is coming from a brand new IP address, they immediately begin to analyze the traffic of that IP.
Because ISPs consider email volume an important factor in determining whether they are spam or not.
So, it’s ideal to start with a small number of emails and then make your efforts to reach more substantial volumes.
This allows email service providers the opportunity to observe and evaluate your email sending habits, and the volume and track how your recipients respond to your emails.

How Do ISPs Evaluate Your Reputation and Emails?
Once you knew how to warm up an SMTP Server IP address and started the warming up process, Internet Service Providers will evaluate your sending Reputation based on 4 main factors:
1. Bounce Rate
When you launch email marketing campaigns, it is important to ensure that the email list you have is valid; cuz a high bounce rate will damage your sender reputation score.
2. Spam traps
Having even the least percentage of spam traps may lead to blocklist you.
3. Spammy content
The content of your email is important. Because ISPs will verify whether you’re using spammy keywords or blocklisted or broken links.
4. User interaction
The way recipients interact with your emails is very important. If they report your email as spam, then this will lead to a real issue!

How to Warm Up SMTP Server IP in Action (Examples)
Now, let’s look at some fundamental techniques to understand the warming up process if you got the idea of warming up an IP address.
Note: These examples are only a guideline and each sender will be different. As well as always be sure to validate your email lists.
1K Emails per day
You need to begin to send 20 emails on the first day and then gradually increase until you reach 1K within 7-10 days.
Use this warm up schedule table to understand how to maintain warm up process:
|Warmup Day||Emails To Send|
10K Emails Per Day
In this case, you have to do the same thing, but with a longer time frame.
|Warmup Day||Emails To Send|
50K Emails Per Day
Currently, 50K emails per day are considered to be a big number.
I suggest you make the process easier for yourself and always divide large volume warmup campaigns into small portions.
So, in this case, I divided the IP warmup schedule into three parts:
- 10K emails.
- 30K emails.
- 50K emails.
However, it is possible to say that this would delay the Warm up process and take more time.
But, I have found that in this way, you can track and manage your warm up campaigns accurately and achieve more effective outcomes.
Or in other words, If you warm up to less number of emails you can monitor and observe the interaction with users and bounce rate.
So, this will assist you to understand better and make everything more transparent. I hope It was clear and you all got the point.
Email Volume and Timeline
The warm up timetable and sending volume differ between all senders in IP Warmup.
How many emails you send will depend on the total volume of emails. Some people might require 100 emails per day, while others might need to send 1 million emails per day.
But in any way, you should always send your emails with sufficient frequency to ensure that you can monitor bounces and reputation.
Note: However, this is very important to know that the majority of reputation systems keep information for 30 days.
So, you have to start sending emails from that IP in those 30 days. otherwise, you’ll have to start warming up once again.
That’s the reason I said IP warmup is a continual procedure.
Marketing VS Transaction Emails
If you would like to use the SMTP mail server for sending transactional emails such as:
- Welcome Emails, or
- Password resets.
In this case, either you are a brand new business or an established one.
Usually, your company’s organic growth will produce an ideal rise in its own way.
Since transactional email is typically determined by the number of customers you have.
So, the expansion of your client base will produce a lovely smooth growth curve for the volume of emails you send.
In this case, you don’t have to stress too much about the IP warmup.
However, it’s still vital to keep an eye on your reputation systems to assess how it’s doing.
If you send lots of emails and decide to move to the other email service providers to start with a dedicated IP address or create your own SMTP.
Then, you have to migrate a smaller amount of emails each time.
One way to accomplish this is to divide your traffic and move small sections of that traffic over to the new IP address as time passes.
However, if you already maintaining multiple mail servers, you may have to change your servers to the dedicated IP addresses each at a time.
Email Marketing Campaigns
The most straightforward method is to calculate your monthly email volume and then divide this number into 30 days.
Then, you should try to divide your emails equally over the 30 days.
If you want to send 60,000 emails per month, you must begin with a daily rate of 2,000 over the first month and later.
Maintain Warm up across all ISPs
It is important to keep in mind that you need to maintain a constant sending volume throughout your own total email volume for every ISP.
Make sure to maintain your warm up schedule longer so that each ISP receives the same amount of mail every day.
But, don’t begin to warm up the Gmail on Tuesday, Yahoo on Monday, etc.
Equally, divide your email among each ISP during each day of warmup.
Otherwise, your activity appears to be irregular, and you’ll not be able to establish a good reputation.
Note: Mix all ISPs, don’t just send to only one at each time.
Tips For How to Warm Up a Server IP Address
The following tips are essential guidelines you must follow while IP warmup:
- Don’t begin until you’ve achieved a high sending score: This can be achieved with the help of rDNS, DKIM, SPF, and other technical information.
