Über diesen Service
Your invoices land in spam. Your newsletter never arrives at t-online. Nobody tells you why, because a rejected mail rarely comes back with a reason.
I check the whole chain and fix what is broken.
WHAT I CHECK
SPF, DKIM, DMARC, MX and reverse DNS.
Blocklists your sending IP may sit on.
A real test send to Gmail, Outlook, GMX, Web.de and t-online, with the check result in the mail header so you can read it yourself.
WHY GERMAN INBOXES ARE DIFFERENT
GMX, Web.de and t-online run their own acceptance rules that nobody outside the German market knows. Two cases from my own work: a mail host without its own A record next to the AAAA record, so IPv4 senders find nothing. And three spaces inside a DKIM key, which quietly kills the signature.
From my own systems, 21,030 subscribers with 3,110 of them on t-online: bounces went from 7.2 percent to 4.8 percent, German core to zero. My own sending IP sat on the t-online block list once. I got it off and proved delivery with a real SMTP handshake.
You get a report with the ready DNS lines to paste and the order to set them in. German is my first language. Write in German or English.

FAQ
Do you need access to my server?
Usually not. SPF, DKIM and DMARC live in your DNS. I hand you the exact records to paste, or you give me DNS access and I set them. For the test send I need one mailbox I may send from.
Can you guarantee my mail reaches the inbox?
No, and nobody can. Providers decide per message. What I can do is remove every technical reason to reject you: authentication, reverse DNS, blocklists, and a sending setup that looks trustworthy.
My mail works fine with Gmail. Why bother?
Gmail is the easiest of the lot. GMX, Web.de and t-online are stricter and quieter about it. If your German customers stop replying, this is usually why.
Do you speak German?
Yes, German is my first language. I work from Osterode am Harz in Germany. Write in German or English, whichever suits you. Same price, same delivery time.
I am on the t-online blocklist. Does Basic remove it?
Basic finds it and tells you why. Getting the IP removed is a separate step, see the T Online Block extra. t-online decides on the request, so nobody can promise the outcome.
