Why is email marketing still relevant in 2025?

  • High rate of return on investment (ROI)Email marketing remains one of the most profitable strategies, with an average ROI of $42 per dollar invested.

  • Direct and customizable outreachEmails allow direct communication with your customers, and you can personalize them according to their interests and behavior.

    Real example: Amazon sends personalized recommendations based on your previous purchases, achieving millions in sales just by email. You can do it too!

Key steps to design an effective email marketing campaign:

  • 1. Define the objective of your campaign

    Do you want to sell more, promote a launch or win back customers? Without a clear objective, your campaign is lost.

     Practical example: A clothing store could send an email with 20% discount only to inactive customers in the last 3 months.

    2. Segment your contact list

    Not all your customers are the same. Divide your base by interests, age, purchase history, location, etc.

     With ClickPanda you can automatically segment according to browsing or purchasing behavior.

    3. Create an irresistible subject

    The issue is your first (and perhaps only) opportunity to get attention.

    Example: "We booked you something special for being our VIP customer!"
    Avoid generic issues such as "Offer available", which are often ignored.

    4. Customize the content of the email

    Use the subscriber's name, show products they have seen, speak their language.

    Example: "Hi Ana, come back to see the shoes you loved" + Product image and "Buy now" button.

    5. Include a clear call to action (CTA).

    The reader must know what to do next: click, buy, schedule.

    Effective buttons: "Get the 30% discount", "Schedule appointment", "Free download".

    6. Design a visually appealing mailing

    Use a clean design, clear images and short text. Make sure it looks perfect on mobile.

    ClickPanda Tip: our templates are 100% optimized for mobile and desktop devices.

    7. Test and measure with A/B Testing

    Send two versions of the email to see which one works better. Change subject, image, CTA, etc.

    Example: In a campaign to sell courses, the version with the CTA "Start today" outperformed the "See more" version by 25%.
