A/B testing different subject lines provides insights into what resonates with audiences. Avoiding spam-triggering words ensures that emails reach the inbox rather than being filtered out. Preheader text also plays a supporting role, reinforcing the subject line’s message. As inboxes become more crowded, subject line optimization will remain a crucial factor in email success.
BEST B2B EMAIL MARKETING STATISTICS 2025 #16. Email Deliverability Challenges:
With nearly 50% of emails landing in spam and 14.3% going directly to spam folders, ensuring deliverability is a major concern.

However, excessive promotional emails may lead to fatigue, increasing the likelihood of unsubscribes. Moving forward, AI will play a greater role in predicting which content is most likely to drive conversions for each individual user. Businesses that balance promotional content with value-driven messaging will see stronger long-term success.
BEST B2B EMAIL MARKETING STATISTICS 2025 #19. Email Frequency Preferences:
Since 44% of consumers unsubscribe when they feel they receive too many emails, maintaining the right frequency is crucial. Overloading inboxes can damage brand perception and lead to higher opt-out rates. Businesses should analyze engagement data to determine the optimal sending cadence for different audience segments. Allowing subscribers to set their email frequency preferences can improve retention. Segmenting highly engaged users for more frequent emails while reducing frequency for less engaged users can enhance overall performance. AI can help monitor user behavior and automatically adjust sending patterns to prevent fatigue. As email volume continues to rise, respecting consumer preferences will be key to sustaining engagement.
BEST B2B EMAIL MARKETING STATISTICS 2025 #20. Mobile Optimization Importance:
