10 Rules for Cold Email in 2025

Tag Title | PDF


Cold emailing is one of the ways to chat with potential clients - but only if done right. Many cold emails fail. Why? Because they don’t speak to the recipient’s needs, are too long or too generic.

Following some basic guidelines (aka cold email golden rules) will help make your emails more engaging and improve the chances of getting a response. In this guide, prepared by DMT Business Development team, we’ll walk through 10 cold email rules that can help make cold outreach more successful and lead to conversations.

What is the most important in cold emailing?

First and foremost, make the email about the recipient, not you. Talk about their needs, challenges, and goals.


How do I make my cold email more personalized?

Use personal connections and be relevant. Reference something personal, such as a recent post, achievement, expansion, industry trend.


How long should cold emails be?

Always keep the email between 50-150 words (=2-3 paragraphs max). Focus on what’s important, skip unnecessary introductions and lengthy explanations. Every sentence should grab attention, highlight a problem, or offer a solution.


How can I use numbers in my email?

Sure! Numbers build trust. For example, mentioning that your solution helped a company reduce costs by 20% shows measurable results and offers specific outcomes for the potential customer’s company.


How do I know the right language to use?

You can use industry-specific terms but avoid jargon that the recipient might not understand. The language should align with the recipient’s role and industry to make the message clear and relevant. If you’re unsure (well, that happens), imagine yourself as an elementary school student, if they understand what you’re talking about, you can send the email.


Why is it important to offer an easy way to reply?

Busy decision-makers don’t have time for lengthy email exchanges. Make it easy for them to respond by offering a simple, low-friction option, like asking if it is interesting or if they want to know more. Same with meetings, suggest exact time of a few time slots.


Should I focus on benefits or features in a cold email?

Benefits. People are interested in how a product will solve their problems or improve their situation, not just how it works. For example, say “Our software saves your team 30% of time” rather than “Our software automates processes”.



Writing effective cold emails is about making them (1) personal, (2) relevant, and (3) easy to respond to. By following these rules, cold emails can transition from being a one-time communication attempt to a conversation.
