What is a Warm Email?

A warm email is a personalized message sent to someone with whom you already have some connection. This could be a: 

• Mutual contact

• Previous interactions

• Shared communities

• Demonstrated interest

The purpose of warm emails is to build on existing rapport and increase the likelihood of engagement or conversion. Warm emails are about connecting with people who have shown some interest in your business by: 

• Visiting your website

• Signing up for your newsletter

• Doing something similar

In warm emailing, you have the prospect’s consent to receive email conversation by showing some interest in your product. Hence, the goal of a warm email is typically to nurture the relationship, provide value, and move the conversation forward in a more personalized and meaningful way.

How to Write a Warm Email That Your Prospects Will Open

Understand Your Email’s Purpose: Start a Conversation

Many sales reps never see success through their email prospecting efforts because they try to do too much in each message. When sending warm emails, you have one purpose and one purpose only: to start a conversation, preferably on the phone, with your prospect. That’s it. In that sense, warm emails are no different than cold emails: You’re not trying to make a sale. You’re not trying to convince the recipient to start their free trial or prove that my company’s offerings are better than the competition. I’m simply trying to book a phone call or schedule a meeting with them. When you understand this, everything becomes much easier.

Know Your Prospect: Research for Relevance

Now that you understand the purpose of your email, it’s time to do research. You need to “know” the person you’ll be contacting: 

• Which company do they work for, and what position do they hold

• The problems they have that my company’s product can solve, etc. 

You can find many of these details via LinkedIn. The more you know about your prospects individually before contacting them, the better. Research allows your messages to sound highly relevant and personalized. It’s how you turn traditional cold emails into a strategic warm email prospecting system.

Keep It Short: Pay Attention to Email Length

Brevity is essential when conducting warm email prospecting. Keep your warm emails short and sweet, around the 125-word mark, give or take. Remember, your prospect didn’t ask me to contact them. They’re probably busy, and if they open my message and see a giant wall of text, they’ll delete it without reading anything. 125 words should be enough to state the value my company brings to the table, establish some credibility, and ask to connect on the phone.

Get on Your Contacts’ Radars: Pre-Contact Outreach

As we mentioned earlier, a pre-contact touch makes your recipients more familiar with you and more willing to open your initial email. That can take several forms: 

• Use your recipients’ email addresses to create a custom ad audience on Facebook or LinkedIn, and run an ad for your company targeting all the people I plan on contacting the following week. 

• Send connection requests to my recipients on LinkedIn before emailing them. 

• Viewing their profiles without making a connection request could get them curious about who I am, so they look at my profile. 

• Ask a mutual connection to send out an introduction email. If my company uses direct mail assets such as postcards or catalogs, send something to my upcoming recipients before I reach out to them personally.

Establish a Meaningful Connection in Your Warm Email

Effective outreach begins with establishing a meaningful connection that resonates with the prospect. This involves identifying a point of commonality, whether business-related (such as a shared frustration with current tools or a recent company achievement) or personal (like a mutual interest). This initial connection aims to build rapport and trust, creating a bridge between the sender and the recipient. By understanding the prospect's challenges or interests, communicators can personalize their outreach and increase the likelihood of engagement, ultimately fostering stronger professional relationships.

Craft an Engaging Email Subject Line

An eye-catching subject line can distinguish between a prospect opening your email and ignoring it altogether. One of the most successful approaches reported by marketers is to personalize the subject line, including your recipient’s first name. For the best results, try to keep your subject line below 50 characters and steer clear of using overly “salesy” language that could be mistaken for spam, like “Buy this now!” or “Hurry before this limited offer expires!” Sales teams can utilize free, AI-powered subject line testing software to see the potential open rates of their emails.

Include Your Warm Email Value Statement

The value statement should be a concise (one to two sentences) articulation of what the company offers, for whom, and its key differentiator. It is crucial to resist the urge to enumerate all features or comparative advantages at this initial stage. The primary goal is to pique the prospect's interest and warrant further discussion, such as a phone call. To maximize impact, the value statement should directly address the prospect's identified pain points, demonstrating a clear understanding of their needs and highlighting the relevant benefits of the solution. This targeted approach increases the likelihood of resonance and engagement.

Build Trust Through Credibility

I must include what Ed calls a “credibility-building URL.” This title is slightly misleading. I don’t necessarily need a link, but I need to share some credibility boosters. A link is just the easiest way to do it in most circumstances. What kinds of things build credibility? It depends on what I’m selling, but I can never go wrong with customer testimonials or case studies. I’ll share if my company has a section on its website containing these materials. I’ll share the stories most relatable to my prospect when sharing case studies. For example, if my prospect works in the health care industry, I’ll send them case studies featuring my other customers. By adding credibility to my warm email prospecting efforts, I’ll convince my prospects that a phone call with me is worth their time.

Add a Clear Call to Action (CTA)

I must end my warm email with a strong call to action (CTA). Fortunately, this step is quite simple. I don’t need to concoct some elaborate CTA or rack my brain trying to come up with the most enticing phrase. Instead, I’ll keep it simple and end my warm email with an invitation to connect. This is best done in the form of a question. For example, “Does it make sense to connect on this?” or “Would you be interested in scheduling a 15-minute call soon?” I always recommend ending my email with a question. Why? Because, as humans, we’ve been trained our entire lives to answer the questions asked of us. Ending my message with a quick query is a small psychological trick to boost my response rate.

Time Your Email Prospecting Well

A well-timed email will likely see more opens and responses, and understanding your audience is the first step to timing my email prospecting well. My email service provider should provide basic email tracking tools that help me determine what days of the week and times of the day prospects most interact with my emails. I’ll use this information to adjust my strategy and send emails at times I think will offer the highest open and response rates.

Remember to Follow Up on Emails

One of the primary reasons for a failed email prospecting campaign is that sales team members often fail to follow up on the emails they’ve sent. In reality, follow-up emails frequently receive a higher response rate than the initial warm email. Ensure I have a structured follow-up strategy to send subsequent emails to my prospects after the first email. While I’ll want to avoid harassing my prospect, it’s also important not to give up and to persevere for as long as possible. Don’t be afraid to use a multi-channel follow-up strategy either. For example, with a text messaging feature added to my CRM, I can follow up using SMS, increasing the chance of my prospect responding.

Optimize Using A/B Testing

Industry benchmarks are a great way to gauge my email campaign’s performance. I can take things further by using A/B testing to optimize my warm email outreach for my target audience. To test and enhance my emails, I’ll create two versions where I change only one element, such as my CTA button placement or the email subject line. I will select two small portions of my target audience segment to receive each email version and use my email tracking metrics to determine which performs better. Then, I’ll send the most successful variant to the remaining prospects on my email list to ensure optimal results. Continual testing in this way will offer deeper insight into what works and what doesn’t, helping me improve my prospecting emails and response rate over time.

Best Practices for Warm Email Outreach: What You Need to Know

Warm email outreach can be a highly effective strategy for garnering new business. Executing a warm email campaign requires strict adherence to best practices to ensure your emails are effective and well-received by your audience. Here are some tips to keep in mind when crafting warm emails. 

Understand Your Audience

Before you start writing warm emails, take the time to understand your audience. 

• Who are you contacting, and why? 

• What do they do? 

• What are their interests? 

• What kind of information are they looking for? 

Segment your email list to organize recipients with similar characteristics. This way, you can personalize your outreach to address the needs of specific groups, helping improve your email open and response rates. 

Craft Relevant Email Content

Once you identify your target warm email recipient and segment your audience, it’s time to start writing. Warm emails should be engaging, provide value, and highlight the recipient’s benefits. Use your research to create relevant content that will resonate with your audience. 

Optimize for Mobile

Did you know that roughly half of all emails are opened on mobile devices? If your emails aren’t optimized for mobile, you risk losing half of your audience. Take the time to ensure your warm emails are responsive and look great on all devices. 

Compliance with Regulations

Even though warm emails are less intrusive than cold emails, you should still adhere to legal requirements. For instance, the CAN-SPAM Act in the United States and the GDPR in Europe lay out rules for sending commercial emails, including warm ones. Following these regulations will help you avoid penalties and ensure your emails reach the intended audience. 

Measuring and Analyzing

Warm emails can enhance your cold email outreach by establishing rapport and trust. It’s essential to understand that warm emails are still a form of email marketing. Like any email marketing campaign, you should track the success of your warm email campaigns through open rates, click-through rates, and conversions to refine your approach. 

Tools for Effective Warm Email Outreach

Implementing the best practices for warm emails can enhance the effectiveness of your outreach campaigns. Utilizing email marketing tools can help you achieve success even faster. Here are some email marketing tools to consider when writing warm emails. 

Email Automation Platforms 

Email automation tools like Mailchimp, HubSpot, or Brevo can simplify your warm email outreach. These platforms allow you to: 

• Automate your email campaigns

• Schedule messages to send when appropriate

• Segment recipients

• Track analytics to measure success

A/B Testing Tools

A/B testing tools allow you to test different versions of your warm emails to determine what resonates best with your audience. Platforms like Mailchimp and HubSpot also include A/B testing features to help you refine your emails for better performance. 

Analytics and Reporting Tools 

Consider integrating tools that provide in-depth analysis and reporting on your warm email campaigns, enabling you to make data-driven decisions. For instance, if you use HubSpot for your warm email campaigns, you can easily track performance metrics and generate reports to help optimize future outreach efforts. 

Considerations for Warm Email Outreach

When sending a warm email, the goal is to build trust and rapport with your recipient. Therefore, it’s essential to personalize your messages based on your recipient’s needs, preferences, and existing relationship with your business. 

Personalization Tools

Use personalization software to personalize at scale, creating individualized content that resonates with your audience. For instance, you might include unique details about your contact’s business, such as recent company news or information about their product or service offerings. 

Customer Relationship Management (CRM) Systems

Customer relationship management systems like Salesforce or Zoho CRM can help you track previous interactions and tailor your warm emails accordingly. These platforms allow you to log communications with prospects and customers to reference past conversations in your warm emails to jog their memory and reinforce familiarity.
