Hi there - we experience huge problems with bounces to all @t-online.de address (which is Germany’s biggest online provider, hence a big problem for as as Germany is our key market). Essentially all e-mails to @t-online.de bounce for several months already, and we now have several thousand suppressed profiles because of that.
I contacted Klaviyo several times and they always say they will look into it (and trying one more time now), however the problem persists.
Does anyone have any advice on how to best address this? Is this something Klaviyo needs to fix (i.e. is Klaviyo getting blocked), or is our domain the problem? Note we just started to set up our own domain in Klaviyo (have added DNS accordingly), but no results yet.
Also does anyone know how I can un-suppress the profiles in bulk?
Thanks for the help, any advice highly appreciated!
