Tutanota frequently appears alongside Mailgun in infrastructure footprints, indicating that organisations using Tutanota mailboxes often also use Mailgun for outbound mail delivery. Senders should ensure SPF, DKIM, and DMARC records correctly delegate to Mailgun's domains, because Tutanota's privacy-centric user base may enforce stricter authentication validation and reject unsigned or misaligned mail more aggressively than mainstream ISPs.
