How to Write a Warm Intro Email [+10 Ready-to-Use Templates]

A warm intro email can be a game-changer.

It only takes a few short lines to build lasting partnerships. By connecting two people together, you can skip the friction of cold outreach, create trust from the start, and open the door for real collaboration. 

But you need to be careful when sending email intros. It’s important not to compromise your relationship with either party. There are plenty of risks—but we’ll show you how to avoid them. 

In this guide, we serve up a simple 5-step process for writing warm intros that work. Plus, we’ve got 10 ready-to-use templates to make your life easier. 

When to use warm intro emails

Warm intro emails are powerful tools for building professional relationships by connecting two people who could mutually benefit from getting to know each other. These emails work well in situations like client referrals, partner referrals, mentorship introductions, or when someone in your network has expressed interest in another’s expertise. 

Sales reps in particular love warm intros because they bypass the difficulties of cold outreach and enable meaningful conversations with high-quality prospects. You can trade warm introductions with vendor partners, tech partners, and consultants so that clients can benefit from trusted relationships within a service ecosystem.

How to get more warm intros

Getting more warm introductions starts with tapping into your network effectively. Cold calling has its place, but a warm intro gets you real-life connections built on mutual trust. 

Try requesting intros from people in key roles—investors, tech partners, ecosystem partners, consultants, C-suite leaders, and colleagues working in departments that match your ideal customer profile. You can also check your LinkedIn connections to identify mutual contacts, so you’re doing some of the legwork and not relying solely on others to find warm leads for you.

Commsor’s Go-to-Network (GTN) platform makes it a lot easier to uncover valuable connections across investor circles, portfolio companies, and partner networks. With Commsor, you can bypass the guesswork, finding warm opportunities automatically and at scale.

What to consider before sending a warm intro email

Proceed with caution. Your professional relationships are some of the most important assets you have. Consider these factors before sending an intro email. 

• Do you really want to send this intro? Just because you have a mutual connection, doesn’t mean it’s a good idea to send the intro. Do a quick gut-check and make sure you feel comfortable before deciding to move forward. 
• Is the intro mutually beneficial? Are you sending the intro purely as a favor to one party? Are you putting your relationship with the other party at risk? If it’s not a win-win, don’t hit send.
• Do you have permission to send this intro? Unless you have an established partnership where you’re exchanging intros regularly, you should probably get permission. You don’t want to put your relationships at risk. We include a request template below.
• Do you have the context you need? Make sure you have all of the information you need to write the warm intro email. If you find yourself uncertain about what to write, get more context. 

Once you’re good on all of the above, you’re ready to write.

How to write a warm introduction email

Follow these simple instructions to craft a compelling introduction email. 

Step 1. Write a clear subject line

A clear, professional subject line helps set the context immediately and guarantees high open rates. Personalization is known to be effective, so go ahead and throw first names in the subject line.

A simple example would be “{Name 1 <> {Name 2} introduction”. Be sure to check out our warm intro email templates below for more example subject lines.

Step 2. Get to the point fast

Start the email body with a quick sentence that explains why you’re making the introduction. This clarifies the email’s purpose right away, keeping it concise and engaging.

Step 3. Introduce both parties concisely

In general, it’s good form to provide a short introduction for both parties. Offer brief backgrounds that highlight why the connection might be valuable.

But for some warm intro emails, it’s not necessary. For instance, with a job referral, you’d typically only describe the experience of the candidate—not the hiring manager.

Step 4. Suggest next steps or let the recipients take the lead

If it makes sense, you can suggest the next steps, such as hopping on a call or sending over a one-pager. 

In most cases, however, you should encourage the parties to continue the conversation on their own. You can write something like, “I’ll let you take it from here,” to signal to both parties that they can remove you from their replies to the email thread, or start a separate thread without you. 

Step 5. Proofread carefully

Double-check names, titles, and other details to ensure accuracy. Small errors in a warm intro email can come off as careless, so take a moment to make sure everything is correct.

Mistakes to avoid when sending warm intro emails

Want to keep things from getting messy? Avoid these mistakes when sending warm introduction emails.

• Getting caught in the middle of ongoing conversations - Separately ask the person who’s going to take over the conversation to leave you out of the rest of their emails. If they forget, you can always give them a reminder via Slack or email. 
• Failing to clearly state the purpose of the introduction - Everyone is busy. Everyone has too many emails and too much on their plate. Avoid sending introductions that lack a clear purpose, otherwise you’ll tarnish your own reputation and be seen as someone who’s good at wasting time. 
• Oversharing or providing irrelevant background information - When sending your intro, don’t provide more information than is necessary. The only context needed is why you’re sending the introduction and how the intro is beneficial to the recipient. Make sure not to share too many personal details or write overly complicated introductions. 
• Sending follow-ups - In general, it’s best to avoid sending follow-ups, unless you know the two people very well and have gotten explicit permission. Before sending the intro, come to an agreement on follow-ups with the person hoping for a potential collaboration. Let them know if you don’t want them to follow-up to the email thread, or if you’re comfortable with them following up once.

Mastering the art of warm introductions transforms your network into a powerful asset, unlocking meaningful connections for you and the people you know.
