1. Sender Address

• Does the recipient clearly recognize your sender address? A trustworthy and familiar sender address increases the likelihood that your email will be opened.

2. Subject Line

• Does the subject line spark the interest of your target audience? An engaging and relevant subject line can significantly influence the open rate.
• How about a personalized subject line? Personalization can boost interest and relevance for the recipient.

3. Quality of Address Database

• Are these contacts you’ve been nurturing for a long time, or are your recipients surprised to receive your newsletter? A well-maintained and up-to-date address database is crucial for your mailings’ success.

4. Sending Time

• When is the ideal sending time? You can determine this by observing traffic patterns on your website. On which day and at what time is the traffic highest?
• You can also find the optimal sending time through A/B testing.

5. Balance Between Images and Texts

• Are images and texts balanced? A picture is often worth a thousand words. A balanced mix can enhance the appeal of your newsletter.

6. Regular Changes

• Do you regularly change the visual and textual elements of your newsletter? Variety keeps recipients interested and can improve open rates.

7. Technical Aspects

• A lower open rate doesn’t necessarily indicate poor newsletter design. Increasingly, email clients block the automatic loading of graphics in HTML emails, which is necessary for measuring open rates.
• Recipients who view emails in plain text also don’t contribute to the open rate.
