Write subject lines that encourage opens

Subject lines should quickly communicate value and spark interest without sounding overly promotional. Clear and specific language tends to perform better than vague announcements.

For example, a clothing brand may see stronger open rates with a subject line like “The jacket everyone keeps asking about is back” rather than something generic like “New arrivals available.”

Testing subject lines regularly helps identify what resonates most with your audience. To learn more about A/B testing within email marketing check out this article: https://www.bluecore.com/blog/ab-test-email-subject-lines/

Use preview text to add clarity

Preview text supports the subject line by providing extra context. Instead of repeating the subject line, it should explain why opening the email is worth the reader’s time.

A clothing brand might pair a subject line about a seasonal launch with preview text such as “Three versatile pieces customers are styling right now.” This reinforces value and sets expectations.

Send emails at strategic times

Timing affects visibility. Emails sent when audiences are busy are more likely to be ignored or overlooked.

While the best time varies by audience, reviewing analytics can reveal when subscribers typically open and click. Testing different send times allows brands to align emails with real behavior instead of assumptions. Read this article to learn how automation will drive email marketing in 2026.

Segment your audience for better relevance

Sending the same message to every subscriber often leads to lower engagement. Segmenting your list allows you to tailor content based on behavior or interest.

For example, a clothing brand could send early access emails to repeat customers while sharing product education with new subscribers. More relevant messaging leads to stronger opens and clicks.

Focus on one clear call to action

Each email should guide readers toward one primary action. Too many links or competing messages can reduce conversions.

Whether the goal is reading a blog post or visiting a product page, the call to action should be clear and easy to find.

Here are some examples of a clear call to action: 
– Read article to learn how to increase email conversions
– Click link in bio to shop new arrivals

Optimize emails for mobile readers

Most emails are opened on mobile devices, so layout and readability matter. Short paragraphs, simple formatting, and clear buttons help readers quickly understand the message.

Previewing emails on mobile before sending helps ensure a smooth experience.
