5 tips for email subject lines in retail

In retail, email marketing is an indispensable tool for effectively reaching and retaining customers. The design of the subject line plays a decisive role here, as it is usually the first point of contact with the customer and determines whether an email is opened at all. Similar to the headline of an article, the subject line must immediately arouse interest and convince the recipient that it is worth opening the message.

Retail companies should consider the following tips when designing their email marketing subject line:

1. clarity over creativity

A clear and direct subject line is often more effective than an overly creative, playful or ambiguous one. Consumers appreciate directness, especially in retail. A subject line must make it clear at first glance what the customer can expect when opening the email. The challenge is to grab attention without being misleading. A meaningful subject line clearly stands out from the multitude of transactional emails, which can be a decisive competitive advantage. The length of the subject line is an important aspect, especially on mobile devices, where often only the first 30 to 40 characters are displayed. Most successful subject lines are between 26 and 50 characters long.

2. use personalization

The personalization of subject lines plays another crucial role in the success of email campaigns. By addressing the recipient directly, e.g. by integrating their name and specific interests, the open rate can be significantly increased as the recipient feels directly addressed. This has also been proven by studies: according to Optimizely's Email Marketing Benchmark Report , addressing recipients personally in the subject line of an email increases the average open rate by 22% compared to non-personalized subject lines. In individual sectors such as tourism, the email open rate with personalized subject lines reaches peak values of 47 percent. But even lower values, such as 20 percent in the fashion industry, are still a remarkable result.

Personalized subject lines not only promote customer loyalty, but also increase the likelihood that the email will be opened. Over 90 percent of successful email campaigns use personalized subject lines.

3. arouse curiosity

Curiosity is a powerful motivator that also pays off in email marketing. A well-formulated question or the hint of interesting content without giving it away completely can motivate the recipient to open the email to find out more. However, caution is advised here: The content of the email should always deliver what the subject line promises in order not to undermine trust and credibility.

4. convey urgency and exclusivity

"Today only", "Exclusive offer" or "Last chance": Subject lines that convey a sense of urgency or exclusivity are very effective as they play on consumers' fear of missing out. However, they should not be used excessively to avoid losing their impact.

5 Test and optimize

The perfect subject line does not happen overnight. It requires experience and a good feel for the target group. Continuous testing of different subject lines is therefore a must in order to find out what resonates best with recipients. A/B tests are particularly valuable here, as they enable a systematic comparison of different approaches and identify those that achieve the best open rates. The use of AI in email marketing can be worthwhile here to quickly generate different subject lines and then test them.
