In recent years, many have begun to question the power and effectiveness of cold emails. With ongoing disputes about their legality and a growing disdain towards spam-like tactics, it’s no wonder that cold emails have gained a somewhat notorious reputation. However, our extensive experience with cold email campaigns, cultivated over many years, tells a different story. When a cold email is crafted thoughtfully, paying close attention to all the recommended strategies, it can prove to be incredibly effective.
In this article, we’ll dive deep into one of the most critical aspects of cold email campaigns – the subject line. A well-formulated subject line not only catches the attention but also sets the stage for the message’s acceptance. We’ll explore the best practices for writing compelling subject lines, discuss which types perform better, and provide 25 proven examples that have yielded success in our campaigns.
Understanding Cold Emailing
Cold emailing is a technique used primarily in sales and marketing where emails are sent to potential customers who have not previously interacted with the sender. Unlike warm emailing, where there’s already some established relationship or prior contact, cold emails reach out to new leads or prospects with the aim to initiate a conversation, promote a product, or propose a collaboration.
The purpose of cold emailing is to open new business opportunities, increase brand awareness, and ultimately, drive sales or partnerships.
The subject line in a cold email holds unprecedented importance. It acts as the first impression and often the deciding factor in whether an email is opened or ignored.
A compelling subject line serves multiple crucial roles:
- Captures Attention
- Sparks Interest
- Sets Expectations
- Enhances Deliverability
Crafting the Perfect Subject Line
Key Elements of a Successful Subject Line
A good subject line is far more than a catchy phrase; it’s an important element of your email marketing plan that calls careful thought. The following are the main components for a strong topic line:
- Your subject line should succinctly and clearly capture the contents of your email. Try for simplicity; subject lines with less than 50 characters usually shine since they are quick to glance over.
- Including the recipient’s name or allusions to their particular industry, company, or interests will help to raise open rates. Personalizing the email gives it more of a tailored feel and less mass mailing resemblance.
- Encouragement of urgency or scarcity among recipients will help them to act right away. Phrases like “limited time offer” or “last chance” demand quick attention and response.
- Posing a question or generating a curiosity gap will inspire ideas or interest, therefore increasing the likelihood that the recipient will open the email in search of the response.
- Clearly stating a benefit in the subject line will allow the recipient to understand the need of opening the email. Tell them what more reading will help them to get.
What to Avoid in Your Subject Line to Prevent Being Marked as Spam
There are some mistakes to avoid in developing your subject lines to guarantee your cold emails find the recipient’s inbox instead of the spam bin.
- Steer clear of regularly used spam-related words and phrases including “free,” “guarantee,” “no risk,” and “this is not spam.” These can cause email filters to turn on and reduce deliverability.
- Writing in ALL CAPS or using too many punctuation marks like several exclamation points (!!!) can be considered as aggressive or spammy, which would cause spam filters or deter recipients.
- Check that your subject line fairly captures the contents of your email. False subject lines not only annoy receivers but also over time compromise the deliverability and reputation of your brand.
- Steer clear of too broad or unclear subject lines that fail to convey the particular email goal. More often than not, generic comments are overlooked and less likely to captivate the recipient.
Passing Through Spam Filters
Successful email campaigns depend on your cold emails reaching the recipient’s mailbox instead of being trapped in spam filters. These techniques and advice will help your email to be more deliverable.
✅ Use email authentication rules like DMARC (Domain-based Message Authentication, Reporting, and Conformance), DKIM (DomainKeys Identified Mail), and SPF (Sender Policy Framework). These confirm that your email isn’t being faked and comes from a reputable source.

✅ Eliminate inactive members and incorrect email addresses to routinely clean your email list. Important elements for evading spam filters are your general engagement rates and sender reputation, so this increases both of them.
✅ Choose a credible email service provider (ESP). An ESP with a solid standing guarantees that big email providers will probably accept your emails.
✅ If you are sending a lot of emails, use “warming up” your IP address—that is, progressively increasing the quantity of emails sent across time. This maintains the reputation of your sender without frightening the spam filters. You can use email deliverability tools, like Warmy.io to warm up you domain.
✅ Set up feedback loops with ISPs so that, should recipients mark your email as spam, reports are generated. This input can help you change your approach and lower spam complaints.

Creating Catchy and Interesting Subject Lines
How to capture attention quickly.
Capturing attention quickly is crucial in cold emailing, where you often have just a few words to make an impression. A subject line must be immediately engaging to stand out in a crowded inbox. The key is to spark curiosity or offer a compelling benefit that resonates with the recipient’s needs or interests. For instance, starting with action-oriented verbs or posing a provocative question can grab attention faster than a generic greeting.
The balance between intriguing and clear messaging.
Balancing intrigue with clarity in your messaging is equally important. While it’s tempting to use clever or mysterious phrases to pique interest, the subject line must still give a clear indication of what the email contains. This ensures that even if you attract the recipient’s attention, you also set the right expectations, leading to better engagement with the content of the email. This balance helps maintain trust and interest, encouraging the recipient to read on without feeling misled.
Increasing Email Open Rates
Several strategies can be used rather successfully to increase open rates through subject lines:
👉 Including the recipient’s name, address, or other particular information will help the email to feel more relevant and personalized, therefore raising the possibility of the email being opened.
👉Subject lines that express urgency or shortage force readers to respond swiftly. Lines like “Ends Tonight,” “Limited Availability,” or “While Supplies Last” inspire instant opening.
👉Use lists and numbers; typically, they grab the attention faster than words. Including figures, like in “5 Ways to Improve Your ROI Today,” will help the subject line jump out and offer quick, practical ideas.
👉Subject lines that raise pertinent questions can pique interest and encourage the recipient to open the email looking for responses. This method starts them in a kind of mental conversation.
👉Connecting your email subject to a popular issue, recent news, or current occurrence can help it to be more relevant and underlined in terms of urgency.
👉Using A/B testing on several subject lines can help you to find which appeals most to your readership. Open rates will rise gradually if you always improve your strategy depending on actual data.
When used carefully, these methods can greatly improve your email open rates so that your messages not only land in the inbox but also generate enough curiosity to be opened and consumed.
A/B Testing and Optimization
A/B testing is a fundamental method in email marketing to determine the most effective elements of your campaign, especially the subject lines. It involves sending two variations of your subject line to a small percentage of your total recipient list to see which one performs better in terms of open rates and, potentially, other metrics like click-through rates or conversions. This method is crucial because even minor changes in the wording, tone, or format of a subject line can significantly impact the effectiveness of your email campaign. By systematically testing these variations, you can refine your approach based on empirical evidence, leading to more successful email campaigns.
How to Conduct A/B Testing
Conducting A/B testing for email subject lines involves several steps:
Identify the Variable. Decide on one element to change in your subject line, such as different calls to action, the presence of personalization, or the tone of the message.
Create Two Variants. Develop two different subject lines (A and B) that only differ in the variable you have chosen to test.
Segment Your Audience. Split your email list into two random, yet statistically significant, groups to ensure that the results are not biased by audience differences.
Send and Monitor. Dispatch your emails with the different subject lines to the respective groups at the same time to avoid variations due to timing.
Measure the Results. Focus primarily on the open rates, but also consider secondary metrics like click-through rates or conversion rates, depending on your campaign’s goals.

Leveraging AI and Automation
Artificial intelligence (AI) is revolutionizing how marketers create and polish email subject lines, hence increasing the data-driven and effective nature of the process. By examining enormous volumes of past email marketing, artificial intelligence systems may identify subject lines that appeal most to particular audiences. Natural language processing (NLP) and machine learning techniques allow artificial intelligence (AI) to create subject lines best for better open rates depending on trends and patterns it finds in user involvement.
Moreover, artificial intelligence can enable mass personalizing of subject lines. To greatly raise the possibility of the email being opened, it can automatically incorporate personal information such the recipient’s name, recent purchase, or browsing history in the subject line. AI systems can also test several emotional tones and phrase combinations, learning constantly which methods produce the greatest outcomes.

One effective strategy is to incorporate industry-specific keywords, which not only grabs attention but also demonstrates your familiarity with the field. Highlighting industry-relevant pain points can also make your emails more compelling by showing empathy and understanding of common challenges.
Mentioning recent news or trends in your subject lines can make your email feel more timely and relevant, thereby increasing its appeal. Including data or statistics relevant to the industry can add a layer of credibility and intrigue, prompting recipients to open the email to learn more.
