It's a new beginning with IP warming. It's a chance to boost productivity, save money, and get your message into inboxes. There are various reasons why email marketers do it, but there is only one method to do it properly.

However, when you deliver, you can't just start paying large amounts of data right away; your IP must first 'warm up.' ISPs are likely to reject your IP if you don't warm it up.

But, before we get into the IP warming discussion, let's define an IP and how it interacts with ISPs in the first place.

Do you want to skip ahead?


IP Warmup Strategy: Best Whole Guidebook

What you should know about IP addresses

The acronym IP stands for "Internet Protocol." An IP address is assigned to a device that may communicate over the internet.

We may use IP addresses to access websites, send emails, and giggle at dogs playing the piano, among other things. Every domain has an IP address associated with it.

In a lot of data, diversifying your IP range might be beneficial. There are several reasons to do so, including (but not limited to) the following:

Deliverability is protected by separating IPs from lower-engaged consumers.

On-time delivery of large-volume email campaigns.

When you put ongage.com into your browser's address bar, the interface is told to look for Ongage's domain. It accomplishes this by determining Ongage's domain's IP address. "A name conveys what we want," said computer scientist JB Postel. Its location is indicated with an address. A route is a map that shows how to go somewhere.

Emails transmit and receive data packets via the internet, which necessitates using an IP address. Your packages will flow if your ISP knows your IP address. It will expel them if they do not comply.

Consider your new IPs as enthusiastic newcomers who must prove themselves before joining the team.

They must first pass a selection panel and tryouts before getting down to the actual job of winning medals for the squad. Then, to advance to the national level, players must demonstrate their abilities via practice sessions and tournaments.

ISPs are similar to the sports team coaches and management, who must be impressed if your new IP's sporting career takes off.

Isn't it memorable?

Now, let's address one of the most common concerns email marketers have concerning IP addresses:

Should you have a dedicated IP address? Or a shared IP address?

A shared IP address is part of a pool of IP addresses.

If you use a shared IP, you'll be sending with a group of other email marketers — for better or worse.

Your sender's reputation may suffer due to no fault of your own. On the other hand, a lousy group will have the opposite impact. A good team of email marketers can help you boost your sender reputation and get your emails inside inboxes.

With a shared IP, you don't have complete control over your sender's reputation, which means you have fewer alternatives for improving delivery.

You have total control over your sender's reputation with a dedicated IP. You are solely responsible for your deliverability, and your performance directly impacts your sender's reputation.

When you start sending emails in large amounts, the benefits of employing a dedicated IP become apparent (i.e., above 100k per month).

High-volume transmissions irritate ISPs. When opposed to shared IPs, using a dedicated IP as a giant email volume sender helps you create a more substantial reputation with the ISPs. Thus a dedicated IP address allows you more control over your sender's reputation.

However, before you sign up for a dedicated IP, you should improve your IP warming game.

Before we go into IP warming, let's address the first question on email marketers' minds:

Do you require several IP addresses?

You might be asking if you need more than one IP at this stage. You most likely do if you send a lot of emails. You probably don't if you don't intend to deliver in large quantities.

Spreading your messages across many IPs can improve deliverability - but this is only true for pros, and take your time learning how to warm your first IP.

Multiple IP addresses come in handy in the following situations:

When you're sending a large number of messages,

When your monthly revenue exceeds $100,000, having multiple IP addresses is useful. This is especially true if your emails are time-sensitive, meaning they must be sent within a specific time.

Imagine you need to send out 500,000 emails by 2 p.m., and you need to reach all of your recipients. This volume of emails will take a long time to send from a single IP address—the probability of all emails landing in the proper inbox.

Splitting the transmission over multiple IP addresses, on the other hand, cuts the transmit time in half with each additional IP address.

ISPs can also limit the number of emails sent from a single IP address, placing you in a bind when sending large numbers. Regardless of how many emails you send, diversifying your IP pool can assist you in getting into the mailbox.

Of course, the preceding is subject to change and is influenced by various circumstances, including the IP address, the ISP, your infrastructure, sender reputation, and so on.

One brand may be able to send millions of emails from a single IP address, while another may require more.

When should you start warming up to a new IP address?

It's required to warm up a fresh IP when:

You're switching SMTP relays.

When you need to utilize a different IP within the same SMTP relay, you could perform the following:

Send a large number of emails.

Send emails from several subdomains and protect specific IP addresses from the consequences of less-engaged users.

It's also worth mentioning that warming up a new IP affects other IPs. It has ramifications across your entire domain. ISPs will trust your domain more in general if you warm your IPs properly.

It also operates in the other direction. If you already have an excellent domain reputation with ISPs, the IP warming period will be much shorter because you already have their confidence.

When sending messages via a shared IP, you don't need to warm up a new IP. However, when sending large amounts of emails, we strongly advise you to use a dedicated IP address.

The IP Warming Method

It's time to get to work. We poured some information bombs here for each stage of the procedure, from authentication through escalation. Here's how to warm up your IP address!

Step 1: Verify the validity of your domains.

If you can't prove who you are, where you're from, and what you're capable of, you'll never make that sports team.

IPs and domains must also show their credentials to be considered trustworthy enough to get into the mailbox.

Authentication protocols identify the sender to ISPs. Your emails will appear shady if you don't use authentication measures. Your emails will not be delivered to inboxes if they are not verified.

Setting them up correctly demonstrates that you're a trustworthy sender with good intentions. This enhances your sender reputation and boosts trust in your domain and overall brand messaging.

Do it now, if you haven't already. IP warming is pointless if your authentication procedures aren't configured appropriately.

Consider the following first when developing authentication protocols:

SPF (Sender Policy Framework) and SPF (Sender Policy Framework)

DKIM (Department of Knowledge and Innovation Management) (Domain Keys Identified Mail).

These ought to be the minimal minimum that you implement.

SPF will do a background check to ensure you are who you claim you are.

DKIM protects your emails from tampering by encrypting the headers so that only the intended recipient can open and read them.

After you've completed these steps, you may go on to DMARC (Domain Message Reporting and Conformance).

With a feedback mechanism, DMARC increases deliverability. When DMARC fails, this mechanism fills loopholes in the authentication process and provides senders choices.

When an email violates DMARC, senders can ask ISPs to reject, quarantine, or do nothing with it. Although the ISP retains final authority over what happens to the email, DMARC provides senders with additional transparency.

When deliverability lowers, or someone's email isn't delivered, DMARC data may be pretty helpful in determining what's going on.

Step 2: Create intelligent segments 

You start with your most muscular movements while establishing your value to a selection panel. When selecting your worth as a new sender, you should start with your most vital, most-engaged recipients.

Sender reputation will quickly improve and grow if recipients provide good engagement metrics.

You can use prior campaign interactions to discover your most engaged receivers, but you may not need to. As you launch different campaigns, the engagement statistics will soon accumulate.

Try looking at alternative measures if you don't have this data—for example, the date of the last login or the previous membership. Historical campaign data, especially when it comes to opt-in dates, may be more relevant in some circumstances than current data.

Someone who has recently joined your mailing list, for example, is more likely to interact with your emails. This information may be used to segment subscribers and is included in the time stamping that new subscribers receive when they join the database.

Segment and exploit your most engaged audiences to impress ISPs in these early days. Automation rules can assist you in accomplishing this in two ways:

Send a delayed transactional message to those with fabulous open and click rates. If someone clicks on your transactional messages frequently, send them two instead of one (with a delay of a day or so in between).

By focusing on the goal. You may designate a recipient's intent based on the message or link they clicked.

Then, depending on that, you may send a follow-up message. For example, if you include Amazon, Google, or Microsoft information in your emails and the receiver clicks on an Amazon link, send a separate message containing only Amazon-related content.

But keep in mind to take it slowly.

Running into the arena and expelling all of your energy in the first five minutes will weary you and not impress the selection panel. ISPs will be concerned if you get into high-volume transmissions (even to engaged receivers).

Step 3: Putting your plan into action

You are warming up your IP manually.

We propose that you apply the following procedures for ramp-up approach 1:

Make sure you have everything you need. Ongage has a segment setting called "All list members." This or a similar feature supplied by your email marketing software should be used.

Make a list of all the segments you want to keep track of. Use the behavioural filter 'Sent in the previous 30 days to isolate a component inside the 'All List Members' metric.

Make a campaign and submit it. Include 'All list members' and exclude 'Sent in the previous 30 days when creating your campaign using the 'include/exclude' toggles.

Make quotas for mailing. Limit the number of emails you send by going to 'Advanced settings' (according to your quota for that day).

Repetition is the key! With this tool from Ongage, you can easily clone campaigns:

The following steps should be used for ramp-up technique 2:

As you would for a ramp-up, prepare your portions.

Use the include/exclude toggles to include 'All list members' and 'Sent in the previous 30 days when setting your campaign. Then select 'Send according to order' from the drop-down menu.

Duplicate and re-duplicate until you've exhausted your options.

Step 4: Keep a close eye on your results

You've made it past the vetting process. You've made it to the tryouts stage. You did an excellent job! However, you can guarantee that the instructors will be watching your every action for the following few sessions.

If you want them to move you to the next level, you must be hyper-aware of your form, fitness, and performance.

Early engagement numbers are similar to IP trials. They're crucial for ISPs to recognize you as a legitimate sender.

Keep a close eye on your results

Remember that to make the team, and you must please each ISP. As previously stated, ISPs react to IP warmup techniques in different ways.

If you start seeing warning indications (such as a declining open rate) with Gmail but not with Yahoo, separate your campaigns by ISP and continue with Yahoo while slowing down for Gmail.

Like you would segment and customize your marketing for various audiences, you should segment and personalize your warmup campaigns for multiple ISPs.

Keep a close eye on your email stats after each send:

Has the number of people who bounced increased? Reduce the intensity of your marketing.

Have you seen an increase in spam complaints? Cool down your campaign and make sure your unsubscribe button is visible.

Is there a decline in click-through rates? Falling click rates indicate that your audience is no longer interested in you. It may also indicate a problem with your sender's reputation and cause it to deteriorate.

Examine the settings and messages for your campaign. Perhaps you're communicating with the same (or similar) people. Examine whether your engagement rates suffer across the board or whether the problem is isolated to a particular ISP. This might suggest a problem with your ISP's reputation.

Free tools are available from Google, Microsoft, and Verizon to help you verify your sender's reputation and deliverability. Gmail Postmaster is a valuable tool that can help you understand your reputation without guessing.

It will inform you whether your ISP rates you as a Good, Medium, Low, or Bad sender at a glance. It will also provide information on authentication failures, spam complaints, and other relevant information. The Microsoft SNDS for Outlook and Hotmail and the Verizon Postmaster Tool for Yahoo and AOL function similarly.

Step 5: Increase the size of your efforts

It's time to scale after your metrics have stabilized and everything appears to be in order.

Continue to send to the same hyper-engaged demographic, but increase your daily sending restrictions.

If your stats continue to be good, you may gradually add your less-engaged users to the mailing list. Just make sure you don't add inactive people!

You may have to scale up and down a few times to get your metrics in order. Don't worry — it's pretty standard! It's all part of the pre-game routine.

After scaling, you'll alternate between steps 5 and 6 as needed, changing your:

Segments for inclusion and exclusion.


We are sending large amounts of data (cooling down and ramping up when possible).

If you follow these steps correctly, you should have an outstanding IP reputation in weeks. ISPs will adore you, and your emails will always be delivered to the inbox.


Warming up your IP takes a long time and a great deal of patience. If you don't properly warm up your IP, you'll never be able to stretch your email marketing muscles to their utmost extent. Even if you can regain your sender's reputation after failing to impress the IP 'coaches,' it will be difficult. It is, nonetheless, worthwhile.

We hope you'll find this tutorial helpful. On the podium, I'll see you!
