What is Email Warm up?

Email Warm up is the process of increasing email reputation across different email service providers. However, it is a long procedure, so it needs some patience. 

In the warm up process, you have to send emails to actual recipients to warm up your email account and emails have to be sent based on a schedule with limited numbers. 

Furthermore, email warm up reduces the bounce rates and increases the delivery rates.

There are two methods to warm up your email account,

  1. Automatic Email Warm up.
  2. Manual Email Warm up.

Automatic Email Warm up?

You have to go with the best email warm up tools to warm up your email account automatically.

Automatic email warm up is far better than manual email warm up.

However, using an email warm up tool takes less time to warm up your email addresses.

Most importantly, they are best for email and domain reputation and bounce rate reduction.

Manual Email Warm up?

In manual email warm up, you have to do everything manually. 

For example,

You have to send emails to an authentic email account by yourself. However, you have to set up a schedule and control everything manually.

But, to regulate everything and make things faster, send emails to your friends and family. This way, you will build a better domain and email reputation on the internet.

Actually, manual email warm up may take up to 2 months longer than automatic email warm up.

For better clarification, learn more here. How to warm up an IP address.

Why Do I Need to Warm Up My New Email Account?

It’s always a good idea to warm up a new email account before you start using it for business needs.

By “warming up” your account, you’re essentially building up your new domain reputation with email service providers so that your messages are more likely to be delivered to recipients’ inboxes.

So, one of the main reasons why you need to warm up a new email account is because most email providers use some form of spam filters to determine which messages should be delivered to users’ inboxes and which ones should go to their spam folders.

However, email providers look at various factors when making these determinations, including,

  • The sending IP address,
  • The content of the emails,
  • Engagement rates,
  • Open rate, and
  • Click-through rate.

Suppose you’re sending messages from a new IP address. In that case, you will have lower email deliverability rates while getting those messages delivered since you don’t have any “history” with the email provider.

So, warming up your email account helps establish that history and improve your chances of delivering your messages to recipients’ inboxes.

Another reason why you should warm up your new email account is to avoid getting blocklisted.

An email provider always keeps lists of known spam IP addresses and domains. 

So, if you start sending many messages from a new IP address, your domain reputation may get hurt, and you can get flagged as spam and blocklisted.

What happens if I don’t warm up my email address?

If you don’t warm up your email accounts, you’re more likely to have your messages delivered to recipients’ spam folders.

Additionally, you may get blocklisted by an email service provider, making it even harder for your messages to be delivered.

So, it’s always a good idea to take the time and start warming up your email account before you start using it for business needs.

How long does email warm up take?

In fact, it varies based on many factors.

It can take anywhere from a few hours to a couple of days for you to warm up your email address. 

Or, it may take longer depending on the number of contacts you have and how often you send emails.

But generally speaking, it’s a good idea to start sending a few messages daily from your new email account and gradually increase the email volume over time.

Additionally, you should focus on increasing engagement rates with your recipients by ensuring that your messages are relevant and interesting.

If you do this, you should start seeing improvements in your email deliverability rates over time.

So, warming up new email addresses is essential to ensure a reasonable deliverability rate and avoid getting blocklisted.

However, once an email address is warmed up, it will be easier to get your messages delivered to inboxes.

The goal is to gradually increase the volume of emails sent so that ISPs (Internet Service Providers) recognize the sender as someone who sends legitimate email communications.

ISPs use various signals to determine whether or not an email sender is legitimate, so it’s essential to make sure all your communications are consistent with that of a trusted sender.

How many emails will be sent while I am warming up my email?

The number of emails you need to send when warming up your account will depend on several factors, including

  • The size of your email list,
  • Your sending frequency, and
  • Your goals.

Typically, we recommend sending a few messages daily from your new email account and gradually increasing the email volume over time.

On the other hand, the number of emails you send when warming up your email will depend on how many new contacts you add to your list each day.

If you’re adding many new contacts, you must increase the daily emails you send.

However, if you’re only adding a few new contacts, you can probably get away with sending fewer emails. But as a general rule, you should aim to send at least 1-2 emails daily when warming up your email.

This will help ensure that your messages don’t get flagged as spam and that your contacts have a chance to engage with your content.

Of course, ensuring that your emails are high-quality and relevant to your audience is the most important thing.

If you’re sending unsolicited or irrelevant messages, you’re likely to see a decrease in engagement, regardless of how many emails you send.

Is email warmup safe for my email account?

Email warming is the process of sending progressively larger volumes of email from a new or recently-changed IP address to establish a good reputation with mailbox providers and ensure deliverability.

Warming up an email account gradually reduces the risk of flagging your emails as spam and can improve your overall deliverability rate.

However, it’s important to note that there is always some risk involved in sending email, and there’s no guarantee that your messages will always be delivered.

If you’re concerned about the safety of your account, we recommend that you consult with an experienced email marketer or deliverability consultant before starting any type of email campaign.

They can help you determine the best way to warm up your email accounts safely and avoid any potential problems.

When I should stop warming up my email address?

The answer to this question depends on many factors, including your sending and receiving volume, email list quality, and overall deliverability.

If you’re sending a high volume of emails (more than 500 messages per day), you may not need to warm up your email address for very long.

On the other hand, if you’re sending a lower volume of email (less than 500 messages per day) or having trouble maintaining good deliverability, you may need to continue warming up your account for a more extended period of time.

Ultimately, it’s up to you to decide when to stop warming up your account.

We recommend closely monitoring your sending and receiving deliverability and making changes to your sending strategy as needed.

To sum up, any email campaigns without an email warm up is always a failure. Especially in cold email marketing, you must warm up your email inbox before sending the campaign.

Your inbox and email reputation depend on the email warm up. Otherwise, your email campaigns will either land in the spam folder or get lost in the way.

However, without email warm up, you will get a hard bounce, and you will be detected as a spammer or get banned for getting multiple hard bounces.

Therefore, choose one of the best email warm up tools for your business growth. But, each email warm up tool provides different features and functionalities. 

So, select the one that is affordable and most suitable for your business.
