Additional steps​

DMARC​

DMARC helps prevent spoofing of your domain and builds trust with mailbox providers. It allows you to enforce alignment of SPF and DKIM, giving you control over how unauthenticated messages are handled.

List-Unsubscribe Header​

Adding a List-Unsubscribe header makes it easier for users to safely opt out of emails. Major providers (like Gmail and Outlook) use this to display a clear “unsubscribe” option, which reduces spam complaints.

BIMI (Brand Indicators for Message Identification)​

BIMI lets you display your official logo next to authenticated emails. While not a direct deliverability booster, it increases brand recognition and signals trust when combined with DMARC enforcement.
