I know everyone is having issues with t-online.de email addresses for some time now.
I’ve implemented all of the suggestions from t-online on my German clients accounts (dedicated sending domains, consistent volume, double opt it, SPF, DKIM and DMARC) and they are still bouncing.
I can live without t-online if it was the only one, but I ran an inbox placement test with Email on Acid and web.de, gmx.de, freenet.de and yandax.com are all going straight to spam too.
It appears these emails aren’t reading the SPF and DMARC records at all:
Is there any solution here? Or even something to try? Feeling hopeless & frustrated 😢
