Sinch Mailgun report: Companies are leaving email performance on the table
Stockholm, Sweden, April 8, 2026 Sinch Mailgun, part of Sinch, today released its Email Impact Report 2026, (https://www.mailgun.com/email-impact-report/) introducing new industry benchmarks across 10 high-volume sending sectors and revealing a gap between email performance and execution. Based on insights from more than 400 billion emails sent in 2025 and a global survey of over 1,200 email senders, the report shows that while email remains a critical, high-performing channel, poor deliverability is leaving significant revenue on the table. Nearly 18% of emails fail to reach the inbox, putting up to a fifth of potential return on investment at risk for many organizations.
