I had authenticate the constant contact emails with a DKIM key since sunday morning. I don't understand why the hornet security is still blocking my mails.
I checked on mxtoolbox and the DKI seems to be invalid.
Could you help me please ?
Hello @AproditeS ,
You may need to check the security settings for your system, see if you also have to safelist our domains if it's particularly aggressive with its filtering. Beyond that, I'd advise calling our Deliverability team to see if they have any specialized insight they can provide.
