When you build a New SMTP Server with a new IP Address, or when you subscribe to an SMTP Service with a Dedicated IP, and Before You can Start Sending Your Email Marketing Campaigns, you have to warm up your IP Address.
Also, you need to warm it up if you left your IP without sending any email for more than 30 days or so.
What is Warming Up IP?
When you have a new Brand IP Address for your SMTP, this IP will have no Reputation on the internet, and ISPs (internet service providers) doest know this IP. SO IP warmup is the practice of building Your Reputation on The Internet by gradually increasing the volume of mail sent with your IP address according to a predetermined schedule.
When an ISP notices an email suddenly coming from a new IP address, they will immediately begin evaluating the traffic coming from that IP. Since ISPs treat email volume as a key in determining spam, it is best to start sending a low email volume, then increasing up your way up to more significant amounts. This gives the receiving email providers a chance to carefully observe your sending habits and record how your recipients engage with your email.
In general, Warming up takes between 2-10 Weeks according to your scenario and the number of emails you want to send per day.
How do ISPs evaluate your emails and Reputation?
When you start the warming up process, ISPs will Evaluate your Reputation according to three Main Factors:
- Bounce Rate: When you send an email campaign, you need to ensure that your emails are valid emails, High bounce rate will destroy your reputation.
- Spam Messages: Your Message content is essential; ISPs will check if you are using any spammy keywords or blacklisted links.
- User Interaction: How Recipients are interacting with your emails, if they are reporting you as spam, then this is a real problem!
Warming Up IP in Action (Examples)
Ok, now after we have the big picture about IPwarmup, let’s go with some examples and real scenarios and understand how the operation works:
1- 1000 Emails Per day: this is not a big deal, you start by sending 20 emails the first day, then increasing gradually to reach 1K in about 7-10 days. The Schedule is described in the following Table:
|Warmup Day||Emails To Send|
2- 10K Emails Per Day: Now, in this scenario, we do the same thing, but with a more extended schedule, check the following table:
|Warmup Day||Emails To Send|
3- 50K Emails Per Day: Now 50K per day is considered somehow a Big Number, as small advice, and to make things easier, always split Large Volume Warmup campaigns into smaller ones, like in our case split it into three schedules:
- Reach 10K emails.
- Reach 30K emails.
- Reach 50K emails.
You may say, this will make the warm-up schedule longer, maybe yes, but in my experience in this way, you can monitor and manage your warming up campaigns easily and get better results.
So if you were warming to 10K, the number of emails would be less, and you can see and monitor the user interaction and Bounce rate on a smaller amount of emails, which will make the picture clearer. I hope you got the point.

Warming up IP Tips:
There are some crucial tips that you have to Follow while warming up IP:
- Don’t ever start before you get a 10/10 sending score: Ensure this by configuring SPF, DKIM, rDNS, and other Technical Details that I Explained in Detail in my courses, if you are interested, you can check my on My Academy
- Don’t ever send promotional emails in the warmup period. You need the highest engagement rates, so send transactional emails or maybe some valuable info.
- Mail only to your top active subscribers first. Ensure almost 0% bounce rates.
- Don’t rotate or switch IPs during warmup. Rotation is a sign of spam.
- In your emails, add a clear link for people to unsubscribe.
- Add Email Signature that makes your emails look trusted.
- Mix your campaigns with premium SMTP services – this will give better user interaction and domain reputation.
- Join News Letters. This will make a lot of emails come to your inbox and give you a Higher domain reputation.
- Send to your friend’s list and ask them to report you as non-spam and tell them to reply.
- Try your best to build adience and warm up to that audience. In this way, you will achieve the best user interaction and will make the “warming up process” a lot easier.
- Monitor your campaigns accurately, and be sure to keep your bounce rate below 2% and ensure your reputation is not going bad.
How to Monitor?
So, you need to monitor your Bounce rate, user feedback, and reputation score.
Monitoring your Bounce rate and User interaction are done through the mailing system like in Amazon SES. This is monitored from your dashboard.
if you are using a Custom SMTP as I explained in My Course: “Build Your Own SMTP and Send Unlimited Emails!”
You will be able to monitor this using your Mailing Software like Mailwizz, or Mailster. Learn More about Bounce Emails in the following Video:
