What makes good sales email subject lines?

The best email subject lines for sales should set clear expectations and respect the reader’s time. To avoid emails ending up in the spam folder, consider these tips:

• Keep it short: Mobile screens cut off long lines, so aim for about 30 to 40 characters or four to seven words. Put key terms first, such as “price update today.” The example below shows subject lines that are being cut off after about 33 characters:

• Lead with value: State the benefit for the reader right away, which could be time saved, discount, outcome, or a new drop. A line like “New report template inside” works great.
• Ensure relevance to the buyer: Match the subject line to the reader’s recent action and ensure that this is reflected in the main message. If they viewed pricing, then reference pricing for consistent messaging.
• Use personalization carefully: Context is more meaningful than simply dropping the recipient’s name. Mention their last purchase or recently viewed products. 
• Make preview text work: Preview text acts as a second subject line that the recipient quickly scans. Add timed power words, and avoid repeating words.
• Test variations: A/B testing different variations for sale email subject lines helps you see what works better before rollout. Test subject lines based on urgency vs benefit or direct vs curiosity.

Subject line mistakes to avoid

The effectiveness of even the most compelling offers can be undermined by mistakes in the subject line. If you want to witness an improvement in the performance of your emails, avoid these common mistakes:

• Using misleading clickbait: When the subject of the email does not match the actual content, the reader becomes suspicious. They are likely to dismiss other emails from the sender too.
• Overusing ALL CAPS or excessive punctuation: Emails such as “READ THIS NOW!!!” are likely to be marked as spam.

• Being too vague: Obscure phrases like “Big News!” give no reason to open. You need clear and direct context, such as “New pricing update.” 
• Making it too long: Long lines get cut on mobile devices. Key details vanish, leaving readers confused.
• Overpersonalizing or sounding intrusive: Referencing sensitive behavior or data can feel unsettling and intrusive. This can damage your credibility.
• Using fake urgency: False deadlines may get you a reaction the first time. However, subscribers won’t fall for it in the future.
• Ignoring preview text: The preview text should not repeat itself and should not contain filler. This is just wasting precious space that could have been utilized.
• Not A/B testing: Lastly, not A/B testing the subject lines can cause confusion about what works and what does not with your audience. It is essential to know what works before rollout.

How to choose the right sales subject line

Choosing the right sales subject line starts with a simple rule: match the wording to the reader’s context and intent, not just the offer. Here’s what to consider:

Consider the buyer’s stage

Cold prospects respond to relevance or mild curiosity that shows you understand their problem. Warm leads react better to direct value or timing cues. 

Meanwhile, existing customers notice product launches, rewards, or restock alerts.

Therefore, find a balance that fits various target groups. Keep wording focused on helping them make a decision. Avoid aggressive urgency tactics this early as that may overwhelm your early-stage prospects.

Segment your audience

Email subject lines for sales must be relevant. Messages tied to actions like viewing a product often outperform broad emails.

Fortunately, many platforms support this level of segmentation. For instance, Omnisend allows targeting by behavior, order data, engagement patterns, and more, as shown below:

Align the subject line with the message

Your subject lines must match the email content and tone. For example, if they promise an update or offer, the email should clearly show that. Always test and refine based on performance data to ensure consistency.

Conclusion

The best subject line for sales is the one that gets your email noticed. However, what works today may not work tomorrow. You have to keep tweaking it as buyer behavior continues to change.

The best way to do this is through constant testing. It works because there is a tendency to observe a pattern when testing multiple variations.

Omnisend offers the opportunity to segment further, test subject lines, and more. Start testing out your subject lines with the examples we’ve given.
