More than half of emails sent worldwide never reach their intended recipients. Why? This is because they never get the recipient’s primary inbox. Instead, they wind up in the spam folder, where they sit for years gathering dust.
Before conducting any cold outreach initiatives, you must warm up your domain if you do not want this to happen to the emails you send.
This article focuses on why you require email warm-up tools, how to create an email warm-up strategy and the best tools.
What Is an Email Warm Up?
It is individual software or an element of an email automation program. An email warm-up software improves your email address’s reputation and raises your daily email-sending cap.
Without an email warm-up service, you cannot send 1000 emails from your current email address on day 1. Email service providers have a daily limit for newer email addresses. For example, Google Workplace users can send 2000 emails daily.
Many email providers have implemented these restrictions as a means of reducing spam. Your email server will suspend your account, or other servers’ spam filters will mark your emails as spam. You start sending emails frequently after receiving a new email address.

How to Create a Warm-Up Email Strategy?
How to warm up email is a common question. Here is a detailed guide to help you with this procedure:
Activate Your Account
Create an account before we discuss ways to warm up for cold emails. Google allows users to purchase domain names. If your company is missing one, you can set one up by registering the domain for a Google Suite account.
The mail-sending service is comparable to Gmail. It is for corporate use and offers better deliverability than a Gmail account. During setup, make sure your email address points to a reliable website.
You can use any of the websites and alter this at any moment. New domains start with a neutral reputation. It will take a while for them to develop a good or bad reputation.
Poor-performing domains could be subject to delivery-related sanctions. Spend time and effort getting your email to warm up to prevent a bad reputation. Before sending out cold emails, waiting at least 12 weeks is best.
If you want to create a new email using an already-existing domain with a strong reputation, send cold emails after two weeks.
Before beginning your email warm-up, your following action should be to customize your account. Making your account more distinctive is crucial for establishing your humanity. By adding a profile picture, you can start personalizing your account. Once logged in to your Google Suite account, select “user” and go to the username.
Then, click the image circle to submit your profile picture from your computer. You will then require an email signature. However, doing so will prevent your emails from entering the spam folder. You cannot utilize your accurate data for the cold outreach account.
Verify Your Email
You must run through account authentication before utilizing your new email address. It protects your account from spam and guarantees your message reaches its target’s mailbox.
The methods of verification of accounts are as follows:
- Sender Policy Framework, or SPF for short, is an authentication technique. It necessitates the addition of a record to your Domain Name System (DNS). It shows each server has permission to send emails on behalf of a particular domain.
- The authentication method known as Domain Keys Identified Mail (DKIM) adds an electronic signature to your domain. By doing this, you can avoid having your email go into the spam bin and guarantee it gets to your recipient’s inbox.
- DMARC tracks your use of SPF and DKIM to ensure your recipient’s ESP is not engaged in fraudulent activity.
Send Single Emails
Scaling back how many emails you send each day will warm up your email address. However, you’ll need to start someplace, and that starting point should be 10 to 20 emails per day.
Additionally, make sure that a majority of those emails receive engagement. This lets your ESP know that you aren’t spamming them and that the content you provide is essential.
You should send emails to accounts from all the leading email service providers. These include Outlook, Yahoo, iCloud, Gmail, and Yandex. You can progressively send more emails per day as time passes.
Keep Conversations in Your Inbox
Email accounts are for more than message delivery. You should also receive some responses. For best deliverability, you must include interactions in your email warm-up. Regular conversations are necessary because this operation will take 8 to 12 weeks.
Increase the number of conversations you have with visitors to your website.This essential email warm-up tool ensures the email operations are authentic to the email supplier. Your account becomes eligible for bulk emailing, such as sending thousands of emails. As a result, the ongoing email dialogue will raise your email-sending quota.
Sign Up for Newsletters
Your inbox’s volume of emails is now just as significant as its volume of outgoing emails. You need to mimic typical email usage to raise that daily sending cap. Additionally, it assists other ESPs and you in validating your email address.
Additionally, newsletters may be the ideal strategy to boost the email volume in your account. Register for at least 15 weekly or daily emails for the most excellent results.
Set Up A Customized Test Campaign
Your account is ready for automatic email marketing after a period of manual email warm-up of 12 weeks, but it’s best to start modestly and manageable. To generate interest and get a response, start with a list of 20–30 reliable recipients, including colleagues and friends. The steps for developing a test campaign are as follows:
Personalize Your Account
You must motivate the recipients to open and reply to your email. You can accomplish that goal by personalizing your email.
Steer Clear of Spam
If you include spam in your emails, SPAM filters may flag your account. Use words like “FREE,” “GRAB,” or “50% off” in your emails to avoid getting flagged as spam by filters. Avoid sending something that will damage your sender’s reputation. Keep the information plain, uncomplicated, and with few links for the best delivery.
Add an Unsubscribe Link
Even if you’re mailing a test campaign to a smaller list, including a link to unsubscribe in your email is a good idea. When warming up your mail account, you should eliminate all possibilities that would spam your mail. One spam report against a brand-new account could harm your reputation.
Create A Qualified Prospect List
Knowing your target market in detail is the most crucial step. You should not skip this step if you promote your business through cold emails. You must first comprehend the kind of client you are watching to tailor and warm up.
You may save time and improve the efficacy of your marketing efforts by understanding your target audience. In addition, you can write an email that addresses their needs and provides a solution.
This application lets you get personalized leads for sizable market segments. When making a perfect lead list, salespeople are the ones who use it most frequently.
