Email Warmup Meaning Explained: A Brief Guide to Boosting Your Deliverability
Rajnish Das
Imagine this: you create a lead list, verify it, purchase an outreach tool, and launch your campaigns. But instead of success, you end up with high spam rates and barely any replies. Soon, your email accounts get blacklisted, leaving you frustrated and wondering if you’ve just thrown your money down the drain.
This scenario is all too common for many agencies and businesses. Some of them claim cold email doesn’t work anymore, but that’s not true.
Cold email remains one of the most effective lead-generation strategies. If you’re facing high spam rates and low engagement, the issue likely lies in your sender reputation.
This is where email warmup comes in. In this article you will find out email warmup meaning, its benefits, and how to do email warm up.
Email Warmup Meaning: What is it
Email warm-up is the process of building a positive reputation for a new or inactive email address before launching cold email campaigns. It involves using automation to send and receive a small volume of emails within the warm up pool, and gradually increasing the volume over time.
For people who're new to this, warm up pool is a network or group of email accounts used in the process of email warm-up by platforms like Manyreach.
Recommended warm-up period for an inactive/old email address is 14 days. For a new sender's address, the warm-up period should ideally last between 30 to 60 days.
Benefits of Email Warmup
The one-word answer to why email warmup is important is deliverability. Warming up a sender’s address before sending bulk emails is like getting to know a friend before visiting their home. In this analogy, the "friend" is the ESP, and you're the new or inactive email account.
Let’s dig into it in detail.
Positive Sender Reputation with ESPs
A new or inactive email has a neutral sender reputation with ESPs like Gmail and Outlook. AI-driven tools like Manyreach help you improve a neutral reputation to a positive email reputation. To do so, they imitate the behavior of a normal email user by sending and receiving a small volume of emails daily.
Low Spam Rate
A new email address that's been in the warmup pool for over two weeks will have a positive sender reputation with ESPs. In simpler words, the ESPs consider your email account as any other regular account used by an email user.
Later, when you send bulk emails, the ESPs are less likely to flag your emails as spam, ensuring a lower spam rate.
Enhance Deliverability Rates
Cold outreach involves targeting a large number of leads to achieve positive results.
To achieve high conversion rates, marketers need to send mass emails. This is where email warm-up becomes such a crucial step, as it helps you scale faster by building a positive reputation.
AI-based tools like Manyreach offer a bulk warm-up feature, allowing you to warm up multiple sender addresses at the same time and accelerate your outreach efforts.
How to do Email Warm Up
To perform an email warmup, you need two things:
✅ Email accounts, obviously
✅ And, an AI-based cold email tool
There are many warmup tools in the market but I recommend using a cold email tool that comes with an unlimited warmup feature. This way, it’s convenient and also economical.
To demonstrate the email warmup process, I am using Manyreach, an email outreach software. It allows its users to warm up bulk sender addresses in one go, allowing you to scale faster.
You can try Manyreach for free. It offers 250 credits without any payment.
Add Email Accounts
Next, add the sender addresses from which you want to send cold emails.
To do that, click on the “Sender” option from the main menu on the left hand side of the screen.
It will lead to a page as below. Now, go to the “Add sender” option as pointed in the image.
You can add a sender’s address to Manyreach in following ways depending your email service provider:
Google Workspace OAuth
Office 365 / Outlook OAuth
Gmail App Password
SendGrid
Custom SMTP/IMAP
The best thing about Manyreach is that you can upload sender addresses in bulk as well. To do so, click on the “Add Senders in Bulk From CSV” option, and upload the CSV file containing details of sender addresses.
Enable Warmup
Once you’re done adding an email address or a CSV file, your sender addresses will appear in the “Senders” section as shown below.
There’s a warm-up icon on the extreme right of each email address as pointed below.
To enable warmup for the email account, click on the warmup icon. It will turn blue, indicating “warmup” activation.
Set the Warmup Settings
To access advanced warmup settings such as “Daily Warmup Sending Limit” and “Increase Daily Warmup Limit”, click on the email address.
It will open the ‘settings’ page. Click on the “Warmup” option as pointed by the red arrow to set warmup settings.
Next, adjust the following settings as per your requirements:
Daily Warmup Sending Limit
Increase Daily Warmup Limit By (Recommended 10%)
Maximum Warmup Limit After Auto Increase
Reply Rate
For a new sender’s address, we recommend the following settings:
Daily Warmup Sending Limit” between 6 to 8 emails per day.
Increase Daily Warmup Limit by 10%
Maximum Warmup Limit After Auto Increase should be 30
50% Reply Rate
And, you're done with warmup settings.
Conclusion
Warmup, as its literal meaning suggests, is indeed a warming-up process for an email account before sending out mass emails. Email warmup ensures efficiency—it enhances the sender's reputation, reduces spam rate, and increases the chances for positive replies.
If you’re planning to send out cold email campaigns, I highly recommend warming up your email accounts for positive outcomes. Check out Manyreach for free. It’s a cold email tool that provides unlimited warmups without charging an extra dime.
To remind someone politely, you have to be direct but kind. Your goal should focus on bringing back their attention, without sounding pushy or forceful.
