Setting a DMARC policy to 'reject' or 'quarantine' without proper SPF and DKIM configuration can cause emails to be blocked or sent to spam. Reviewing and adjusting DMARC policies is essential.

Expert from Word to the Wise (Laura Atkins) responds that GSuite may be caching old reputation data related to the domain, especially if it was previously used for less reputable activity. She recommends contacting Google Workspace support to inquire about the domain's reputation within their systems and requesting a review.

Expert from Spam Resource (John Levine) explains that while a TLD itself isn't typically a direct cause for spam filtering, newer or less common TLDs like .is might face increased scrutiny initially due to lack of established reputation. He suggests focusing on building a positive sending reputation and ensuring proper authentication.

Expert from Email Geeks asks if the Icelandic domain is the only domain associated with that G-suite account, implying this could be a factor.

Documentation from DMARC details that DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that builds on SPF and DKIM to provide domain owners with control over how email receivers handle unauthorized email. Implement and monitor DMARC records to enhance deliverability.

Documentation from DKIM details that DKIM (DomainKeys Identified Mail) adds a digital signature to outgoing emails, which can be verified by receiving mail servers. This helps ensure that the email has not been tampered with during transit and can improve deliverability.

Documentation from GSuite Admin Support provides advice on troubleshooting deliverability issues including checking sending limits and reviewing any unusual activity.

Documentation from Google Workspace Admin Help details best practices for preventing mail to Gmail users from being blocked or sent to spam.
