IP Address Blocked TT406 sending to talktalk.net and tiscali

[Darren_Braze]

Hi, 

I hope you're doing well.

I'm from the Deliverability team here at Braze. We've noticed that our client is seeing the following bounce: 

"Sorry, we’ve identified a number of outgoing emails from your email provider as spam so we haven’t been able to send your email to its intended recipient. Please try again later or using an alternative email address. For more information visit our help article (link: help2.talktalk.co.uk/{hash}) (TT406)"

The impacted IP is 137.22.229.197

Domain: content.jacksflightclub.com

Any assistance to remove this block would be greatly appreciated.

Thanks, 

Darren

Hi Darren, I've added this to the list and reraised it to the network team. I've still not had the answers we're looking for though.

TT406 indicates a block on incoming mail because, as the message says, your email service, Sparkpost Mail / MessageBird has been detected as sending spam to TalkTalk Mail users. So it's really down to the sender to improve their reliability.

How are your other three cases where your clients were getting TT902 Spam protection bouncebacks? TalkTalk's CloudMark was obviously fingerprinting some mail messages as potential spam. I'm just wondering if this is the ongoing reason for blocking Sparkpost Mail senders?

Have you had any feedback from TalkTalk email admins?
