How Long Should A Cold Email Be? [Based on Research]

Crafting the perfect cold email can be tricky. One of the most common questions is how long should a cold email be? Many articles talk about keeping them short, but there's more to it than that. You want to provide enough value about your business, while also keeping engagement high. So, how long should a cold email actually be? The answer may surprise you. In this post, we'll cover how long your cold emails should be for optimal outreach, engagement, and conversion rates. We'll look at how much information to include in your email and how much is too much. If you're struggling with getting responses from your cold emails, you may be making them too short or too long. Let's break it down and find out how long your cold email should be.

Why Cold Email Length Matters

When it comes to cold emailing, there's no denying that it's a powerful strategy for generating new leads and boosting sales. But like any form of communication, it requires a delicate balance. Too short, and your message lacks substance; too long, and you risk losing the recipient’s interest. Finding that sweet spot is crucial for success. 

Crafting the Perfect Length

The ideal length of a cold email typically falls somewhere between 50 to 125 words. This length is long enough to convey your message effectively, but short enough to maintain the recipient's attention. A concise email makes it easier for the recipient to digest the content quickly, increasing the likelihood of a response.

Focusing on Recipient Needs

It's also important to remember that the purpose of a cold email is to pique interest and start a conversation, not to sell your product or service outright. So, keep your email focused on the recipient's needs and how you can help address them. 

Tips to Increase the Chances of a Response

• Focus on the subject line and opening sentence — these are the first things the recipient will see, so they need to be attention-grabbing. 
• Avoid overly salesy language and instead, opt for a personalized touch that demonstrates your value to the recipient. 
• A cold email should be long enough to convey your message effectively while maintaining the recipient’s interest. 

By finding that delicate balance, you can increase the chances of a response and ultimately, a conversion.

How Long Should A Cold Email Be According to Research

The length of a cold email matters significantly. The consensus among experts is that a cold email should range between 50-125 words. That translates to approximately 5-15 lines of text. Keeping it concise ensures your message gets read without overwhelming the recipient.

Research Findings on the Ideal Length of a Cold Email

1. Response rates to emails that were 75-100 words long were a whopping 51%, a study by Boomerang which surveyed up to 40 million emails reported.

2. Another study conducted by email software, Constant Contact, revealed that there was a 16% click-through rate for emails that had approximately 20 lines of text.

3. According to Octopuscrm.io's study examining up to 40 million emails, response rates between 75 and 100 words were staggering at 51%. Another study found that emails with about 20 lines of content had a 16% click through rate.

What Are The Four Elements of an Effective Cold Email?

Deliverability

To make sure your cold email reaches the recipient’s inbox, you must follow best practices for domain setup, warm-up, and sender reputation. Nowadays, many domain providers make it difficult for users to send emails, as a way to prevent spam. That’s why it is essential to have a clean sender reputation and a well-set domain. To do this, you need to maintain high standards of sender reputation through an email service provider, which is why domain setup and warm-up are so important. 

Targeting

Identifying the right audience and building a quality email list are critical elements of successful cold emailing. Having a good email list can be even more important than having a good email. There are multiple ways to gather information for outbound emails, such as database mining, scraping tools, and even purchasing email databases. There’s a hidden gold mine of potential leads you can reach out to. This is known as warm emailing. 

Immediate Appeal

The subject line is the most important element of your email, as it is the gateway to the rest of the email. Most recipients will decide whether to open your email based solely on the subject line.

The greeting is the next most important part of your email. It’s easy to spot a canned greeting from a mile away, and your recipient will easily recognize this as well. The key to a good greeting is personalization. You must say something about the recipient in order to engage them. 

Value

Conveying value is the final and perhaps most important element of a cold email. If you don’t offer the recipient something valuable in the email, they have no incentive to respond to you. Some ways to demonstrate value in your initial email are to clearly explain the benefits of your service, product, or offering and provide a specific call to action.

How To Craft Your Cold Email for Increased Open Rates

Subject Lines That Intrigue

To hook your prospect's attention, personalized subject lines are essential. The recipient sees the subject line first, so it must be compelling. Here are a few examples that could intrigue a prospect:

• "Idea for [Prospect’s Company]’s Q3 Strategy"
• "Question re: [Prospect’s Company] Marketing Goals"
• "Your latest article was spot on!"

Personalized Greetings and Unique Content

To stand out in inboxes, steer clear of generic templates. Always include a personalized greeting; doing so demonstrates you’ve done your research. Offer something unique that your competition hasn’t yet. Think about it from your prospect’s POV; make sure your content is relevant to them.

Clearly Defined Value Proposition

Your cold email should highlight the value you’re offering, whether that be a discount, a free consultation, or premium content. Benefits, not features, are the name of the game. The goal is to show the prospect what they stand to gain by clicking on your email.

Effective

The CTA should be the last thing your prospect reads. When it comes to CTAs, clarity is key. Keep them to one sentence, and be specific about the email’s purpose. The aim is to provide a straightforward directive for the prospect. 

Error-Free Emails

Before you hit send, proofread your email with a fine-tooth comb. Typos or grammatical mistakes can tarnish your professional image. Make sure your email is polished and error-free.

How To Ensure Your Cold Email Deliverability

Email Authentication

To improve the cold email deliverability rate, locking down these three essential protocols is crucial:

1. Sender Policy Framework (SPF)

This record saved in the domain name system (DNS) shows that the domain owner authorized the sending domain to send emails on its behalf.

2. Domain Keys Identified Message (DKIM)

This protocol uses cryptographic authentication to verify if the message content is trustworthy and hasn't been altered.

3. Domain-based Message Authentication, Reporting and Conformance (DMARC)

This protocol works alongside SPF and DKIM to help ensure email authentication and compliance.

Email Sender Reputation

The past performance of your emails determines how ISPs view your sender reputation. To safeguard your sender reputation, these factors matter:

1. Email Engagement

Consistent engagement with your cold emails signals relevance to your recipients, which ISPs appreciate.

2. Domains and Blocklists

Regularly monitoring and addressing your presence on blocklists is key to maintaining a good sender reputation.

Email Bounce Rate

A high cold email bounce rate can hamper your deliverability by keeping your messages out of recipients' inboxes. Reduce the bounce rate by ensuring your emails reach their destination.

Ways to Ensure Deliverability: Key Steps to Enhance Cold Email Reach and Success

1. Warm Up Your Email Account

It's crucial to use the email address for a few weeks before ramping up your cold email outreach.

2. Gradually Increase Outreach Volume

Start with a smaller volume and slowly escalate to ensure you don't trigger spam filters.

3. Verify Your Email List

Regularly clean and validate your email list to improve the deliverability of your cold emails. Consider using separate domains for cold outreach to protect your primary domain's reputation.
