ZeroBounce revealed that email remains a dominant communication tool despite the rise of new digital channels. With 93% of people checking their email daily, businesses must refine their strategies to keep pace with evolving user behaviors. The report highlights key trends shaping email engagement in 2025, including personalization, mobile optimization, and shifting user preferences.
According to the report, email use is expected to continue growing, with more individuals integrating it into their daily routines. 42% of people check their email three to five times a day, while nearly one in five checks more than 20 times daily. This heavy reliance underscores the importance of email marketing and communication strategies that keep pace with changing user preferences.
One major trend is the increasing need for personalization in email marketing. As inboxes become more crowded, generic mass emails are no longer effective. Instead, 46% of users say they open all emails from a brand when the content is consistently relevant to them. Businesses that tailor messages based on user behavior, preferences, and engagement patterns are more likely to capture attention and drive conversions.
Another key finding is the growing importance of mobile optimization. With 64% of users primarily checking emails on their smartphones or tablets, businesses must ensure that their email designs are responsive and easy to navigate on smaller screens. Poor formatting or difficult-to-read emails can lead to lost engagement and unsubscribes.
The report also highlights user habits around email organization. 86% of respondents have at least three email addresses, often separating work, personal, and promotional emails. This means marketers must carefully target their campaigns to reach the most relevant inboxes and avoid being ignored or filtered out.
Email length preferences are another critical factor. 67% of users prefer short, concise emails, while 28% say length doesn’t matter if the content is personalized and relevant. This suggests that while brevity is generally preferred, businesses can still engage users with longer emails if they are well-targeted and valuable.
Deliverability remains an ongoing challenge, as 76% of users check their spam folder, though 25% do so only a few times a year, and 14% never check it. This reinforces the importance of maintaining strong sender reputations, avoiding spam triggers, and following best practices to ensure messages land in primary inboxes rather than being overlooked.
ZeroBounce’s findings provide a roadmap for businesses looking to optimize their email strategies in 2025. By focusing on personalization, mobile optimization, concise messaging, and improved targeting, businesses can increase engagement and maintain effective communication with their audiences. As email habits evolve, companies that adapt to these trends will be best positioned to reach their customers and maximize their email marketing impact.
