But before getting into the most astonishing stats, I would like to acquaint my viewers with the importance of analyzing these statistics.

Importance of Statistics:

1. Increased Open Rates

With a proper analysis of these statistics and trends, businesses can increase their open rates by around 20-22%.

By analyzing data, they can figure out ways like including the recipient’s name in the subject line, which is a simple yet one of the most effective tips for increasing open rates.

Also, businesses should set realistic targets by using the industry average open rates. According to different studies and research, open rates range from 15.22% to 28.46%. This range varies by industry.

Cold email open rates can also be increased by including catchy subject lines. According to studies, 30% of people open the email based on its subject line. Therefore, spending time on creating a personalized subject line actually pays off. Also, a short cold email subject line is preferable as most of the recipients check emails on their phones. Sometimes long subject lines can even form a belief in your prospect’s mind that the email sent is spam. So, avoid using such language in your Emails.

Apart from this, another method is Split Testing. It refers to squaring one Email off against the other to see which one gets the best results and using it as a new test to create another variation. All this information is available in the previous years’ statistics.

2. Improves your Targeting

Stats also help businesses improve their targeting by making several changes in their target lists. The target lists should be concise and properly defined. Think of it as sales emails. Along with the open rate, it’s important to monitor the response rates as well. If your open rate is around 80-90% and your response rate is far below 5%, it is not a good indicator. You need to revisit your subject line rather than give up on cold emailing, as it is an amazing email outreach method.

3. Controls Costs

Stats help find strategies that can be effectively implemented to ensure that when you send a cold email, it is not ignored and produce productive results. The increased open rates, thus, help in reducing costs that can incur due to unopened emails.

Also, sometimes, the emails are undelivered due to the wrong email addresses. The target list can be prepared with the help of these stats, and the addresses can be verified to ensure zero undelivered mails.

4. Improves Reply Rates

Personalized emails help in improving the reply rates of your Emails. Add Personalized bits like using the first name of the recipient or his/her company name and a proper email subject line. This gives a notion to the recipient that you have spent time on writing this Email, and you are able to directly address him/her.

Personalized Emails are a popular feature these days. The recipient feels that the sender has spent ample time writing the Email. A little bit of research on your clients can increase your response rates to a great extent. You should also know the best time to send emails to get a higher response rate. 

General cold email statistics help in combining all the necessary data that eases your work to the maximum extent. Also, follow-up is the most important thing to increase the reply rate in cold emails.

So these are some of the advantages of analyzing Cold Email Statistics.

5. Email Subject Line Statistics

The usual advice to write subject lines is to keep it short to be seen fully on a phone screen. After digging some data and crunching some numbers, some recommendations to the users show that you have to make it very short or long but specifically 45 characters to improve open and reply rates.


The open rates for different subject line word limits are:


3-12 characters : 44% open rate

81-86 characters: 43% open rate

98-111 characters: 54% open rate


It’s a 4-Rule Formula!

1. Identifying Intent:

Identifying the intent of your potential customer holds great importance. If you know that a client has visited your website and has searched for information about your product or service, then it’s a sure sign that they are interested in your product.

Trying to identify their problems and giving them a sure-shot solution helps to grab the deal!
Therefore, sending cold emails to such prospects always yield results.

2. Evaluating Fit:

Not everyone who has shown some intent is satisfied with your product/service. As marketers, you must be capable of identifying your target market and building buyer personas.

3. Choosing the right channel:

It’s not always necessary that Email is the right channel to contact your customer. So if a customer has reached you through your website, try engaging with them on the same platform through messaging rather than sending loads of emails in their inbox.

4. Personalization:

Personalization has become a very popular method these days to pitch your client. Sending a personalized message relevant to a person who will engage with it increases your chances of converting the deal.

And I’m sure by now you know where to get such personalized messages!

7. Rates depending on Content-Length

Content length also affects the statistics, specifically, the open rates. The length of the text should also be just like subject lines, making it short to the point and very specific.

Who wants to work on weekends? The worst time to send someone a work email is on weekends. Your prospect must be spending time with their families, and they are least bothered to check their mails. Your emails will slide down and thus goes unnoticed.

Therefore, try sending emails on working days only. Research shows that the best time to ensure high open rates is Tuesday.

Usually, the bounce rate is expected to be under 3%. If it exceeds, then your email campaigns are affected negatively.
