What is Email Warm-Up?

Email warm-up is gradually increasing your email activity to improve deliverability.

When you start sending emails from a new account, ISPs (Internet Service Providers) don’t know anything about you or your sending habits. As a result, they may view your messages as suspicious and route them to the spam folder.

Warming up your email account helps you build a reputation with ISPs, making your emails more likely to be delivered to the inbox.

Why is email warm-up important?

There are a few reasons why email warm-up is important:

  1. Improve Deliverability – As we mentioned, warming up your email account can help improve deliverability. By gradually increasing your email activity, you’re telling ISPs that you’re a legit sender and not a spammer. This increases the chances that your emails will be delivered.
  2. Build a Reputation – With improved deliverability, warming up your email account can help you build a reputation as a sender. This is important because your reputation can impact things like whether or not your emails are opened and how likely people are to unsubscribe from your list.
  3. Establish Credibility – When you start sending emails, you’re starting from scratch. Warming up your account can help you establish credibility with ISPs and recipients.
  4. Avoid the Spam Folder – One of the main goals of email warm-up is to avoid the spam folder. By increasing your email activity gradually, you’re telling ISPs that your messages are legitimate and not spam.
  5. Improve Email Performance – Warming your email account can also help improve email performance. You’ll likely see better open and click-through rates by building a reputation and establishing credibility.
  6. Get More Opens and Clicks – Warming up your email account can help you get more opens and clicks. When your messages are delivered to the inbox, recipients are more likely to see them. And, if your emails are well-crafted, recipients will be more likely to open and click through.

Email warm-up has many benefits, and these are just a few of them. If you want to improve your email performance, you should consider warming up your account.

How to Warm Up an Email Account?

Here’s how to warm up your email now that we’ve discussed some of the benefits. We are going to discuss two approaches:

1. The Manual Approach:

With this approach, you’ll be manually sending emails from your account. It’s a great option if you have a small contact list or are just getting started.

The manual approach is more time-consuming but is a great way to start. With the automated approach, you can set up your account once and let the software do the work for you.

2. The Automated Approach:

With this approach, you’ll be using software to automate the process. If you want to save time or have a large contact list, this is a great option.

The automated approach is more efficient but requires some initial setup. Once your account is set up, the software will take care of the rest.

When can you stop warming up your email account?

You can stop warming up your email account once you have reached your target number of contacts or when your sending reputation is strong enough to support the amount of email you want to send. Warming up an email account is gradually increasing the number of emails sent from an account to build up a good reputation with ISPs and avoid spam folder placement.

If you’re not sure how many contacts you should have in your account before you stop warming it up, a good rule of thumb is to have at least 50% more contacts than the amount of email you plan to send on a daily basis. So, if you want to send 100 emails daily, you should have at least 150 contacts in your account.

Remember, the goal of warming up an email account is to increase your sending volume while maintaining a good reputation gradually, so there’s no need to rush the process. Just be sure to add new contacts regularly and keep an eye on your deliverability rates so you can make adjustments as needed.


Email warming increases engagement with a prospect’s email address before attempting to sell something. This approach can help you avoid spam filters and get your message in front of more prospects.
