Migadu is an email hosting provider that manages inbound and outbound mail for organisations and individuals. It serves as the primary mailbox handler for a diverse range of smaller and mid-market websites globally, particularly across US-focused and international domains.
Senders reaching any broad audience will regularly encounter Migadu-hosted mailboxes. The frequent co-occurrence with Amazon SES indicates a split-stack pattern—Migadu handles inboxes whilst organisations use external services for sending—a distinction that affects how you should approach authentication testing.

Strict authentication expectations
Migadu-hosted organisations typically enforce strict SPF, DKIM, and DMARC alignment. When paired with Amazon SES, this expectation becomes more pronounced—organisations using external sending infrastructure are less tolerant of authentication failures, viewing them as misconfiguration rather than transient issues. Senders should include Migadu addresses in authentication testing, especially when targeting the smaller-to-mid-market segment where Migadu dominates.
