Mailgun's “State of Email Deliverability 2025” report surveys 1,100 email senders globally, highlighting the importance of adapting to new inbox requirements from providers like Gmail and Yahoo. Key findings include challenges in deliverability, lack of list hygiene, and inadequate monitoring of email blocklists. The survey indicates a need for better email practices, with significant awareness of authentication requirements but many senders not implementing necessary changes. Prioritizing deliverability improves not just email success but overall customer experience.
