Improve email deliverability: SPF, DKIM, DMARC & newsletter infrastructure.
Many business emails and newsletters fail to arrive reliably because domain, mailserver, and authentication aren't configured properly. Often it's not the content — it's the technology.
Check email deliverability / newsletter delivery →Emails land in spam or don't reach Outlook, Hotmail, GMX, Web.de, or T-Online at all. Newsletters get delivered worse than expected. Usually it's missing or misconfigured authentication, weak server reputation, and neglected mailing lists.
With properly configured SPF, DKIM, DMARC, and Reverse DNS, mail providers can verify that an email truly comes from an authorized server — this improves deliverability and protects against sender spoofing. Many extortion emails appear to come from your own address; only the visible sender is forged. Add proper bounce management: remove invalid addresses and spam traps, maintain reputation. On request, via your own mailserver with dedicated IP — as an alternative to expensive external newsletter providers. A self-test for deliverability is planned as a future service.
