Do your Emails go to the spam folder? It’s OK, don’t worry. I will show you How to Warm Up SMTP Server IP.
It is usual for emails to go to the spam folders for newbies in Email marketing using a new SMTP Mail server with a new domain and IP.
However, even if you have set all the technical components like DMARC, RDNS, SPF, DKIM, No Blacklists, and have a 10/10 Score from Mail-Tester.com. Your email could be discarded in the spam box.
If you are using a new SMTP Server with a new IP Address or signing up for an SMTP Service like Amazon SES with a Reliable IP, you must warm up your IP Address before sending any Email Marketing campaigns.
Additionally, it is necessary to warm up your IP Address if you have left your IP and didn’t send an email for 30 days or more.
Thus, SMTP Warm up is an ongoing process.

Now let’s dive into How to Warm Up SMTP Server IP.
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 Warm up 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 an Internet Service Provider detects that an email is coming from a brand new IP address, they immediately begin to analyze the traffic of that IP.
Because ISPs take email volume as an important factor in determining whether they are spam, it’s ideal to start with small amounts of email 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.
The general rule is that the process of warming up an IP can take between 2 to 10 weeks, depending on your situation and the number of emails you plan to send each day.

How do ISPs Evaluate Your Reputation and Emails?
Once you have come to know how to Warm-Up SMTP Server IP and started the process of warming up, Internet Service Provider will evaluate your sending Reputation based on four major factors:
1. Bounce Rate
When you launch an email marketing campaign, it is important to ensure that the email list you have is valid; a high bounce rate will damage the reputation of your business.
2. Spam traps
Actually, the least percentage of spam traps may lead to blocklist you.
3. Spammy content
The content of your email is important; ISPs will verify whether you’re using harmful keywords or blocklisted or broken links.
4. User interaction
The way recipients interact with your emails is most important. If they report your email as spam, this will be a real issue!
How to Warm Up SMTP Server IP in Action (Examples)
OK, now that we have the overall picture of how to Warm-Up SMTP Server IP and run SMTP, Let’s look at some fundamental techniques to understand how the process works:
Note: These examples are only a guideline. Each sender will be different. As well as always be sure to validate your email lists. Learn here What is Email Validation – All You Have To Know.
1K Emails per day
It isn’t big deal; you begin to send 20 emails on the first day and then gradually increase until you reach 1K within 7-10 days.
I have described the schedule in detail in the following table:
|Warmup Day||Emails To Send|
10K Emails Per Day
In this case, we’ll do the same thing, however, with a longer time frame.
Look at the chart below:
|Warmup Day||Emails To Send|
50K Emails Per Day
Currently, 50K emails per day are considered to be a big number.
We suggest that to make the process easier, and always divide large Volumes of Warm-ups into small groups, as in our case, we scheduled it into three parts:
- 10K emails.
- 30K emails.
- 50K emails.
It is possible to say that this would delay the Warm up time; however, I have found that in this way, you can track and manage your Warm up campaigns with ease and achieve more effective outcomes.
In other words, If you were warming up to 10K, the number of emails may be less, and you could be able to monitor and observe the interaction with users and bounce rate for a lesser amount of emails. This will assist in making things 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 Warm up.
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.
In any event, you should send your emails with sufficient frequency to ensure that you can monitor your email reputation.
Note: Additionally, you must be aware of something very important. The majority of reputation systems keep information for 30 days.
Therefore, you shouldn’t miss sending emails from that IP in these 30 days. If you do so, you’ll have to Warm up once again.
That’s the reason I said IP Warm up is a continual procedure.
Marketing VS Transaction Emails
If you would like to use the SMTP mail server for sending transactional emails Like: (invoices, welcome emails, Password resets) in this scenario, you could be either 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, the expansion of your client base will produce a lovely smooth growth curve for the volume of emails you send.
So, in this case, you don’t have to stress about warming up. However, it’s still vital to keep an eye on your reputation as well as your system to assess how it’s doing.
If you send lots of emails, and you choose to move to an ESP to start with a dedicated IP or create your SMTP, you have to migrate to a small amount in one time.
One way to accomplish this is to divide your traffic and move small sections of that traffic over to the new IP as time passes.
Alternately, if you already manage more than one mail server, you may change your servers to the new IP address each at a time.
Email Marketing Campaigns
The simplest 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.
For instance, 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 volume throughout your whole Warm up time for every ISP.
Make sure to divide your Warm-up schedule so that each ISP receives the same amount of mail every day. 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. If you don’t, 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 SMTP Server IP
The following Tips are essential guidelines you must follow while warming up IP:
- Don’t begin until you’ve achieved the highest Sending Score: This can be achieved with the help of rDNS, DKIM, SPF, and other technical information.
