Why e-mails from your domain land in spam, and how to fix it. We explain SPF, DKIM, DMARC and MX records in plain words, with example DNS entries. Articles show common mistakes such as too many SPF lookups, missing DKIM selectors or a DMARC policy that is never enforced. Each guide ends with the exact records to add or change. We also cover how to protect your domain from people sending e-mail in your name. Good e-mail authentication makes invoices, offers and password resets reach the inbox.
