Our emails land in spam for one inbox provider but inbox everywhere else – what do we do?
Klaviyo verified TL;DR: Provider-specific spam placement usually signals a reputation issue with that provider. Set up a dedicated click tracking domain, then run a targeted warm-up for those users specifically.
Full answer: When you're inboxing everywhere except one provider, that provider's reputation score for your sending domain has likely dipped – often due to low engagement from that subset of users. Two steps help most: (1) Set up a dedicated click tracking domain so your links align with your sender address (contact Klaviyo support – it's free). (2) Run a mini warm-up targeting only your most engaged users at that provider, monitoring metrics as you go. For Outlook specifically, also check for any reputation or volume changes around when the issue started – Outlook can be triggered by sudden shifts.

Hi Shareen and Hugues
We are struggling with deliverability with Verizon (Yahoo & AOL) mailboxes. We use a professional deliverability suite and notice that all our emails land in Spam with Verizon mailboxes. With all other providers, we land perfectly in the Inbox. Unfortunately, Yahoo customer service cannot help as we cannot access the headers of the emails we send through Klaviyo. Do you have a suggestion on how we could solve this?
Thanks!
Philippe
Hello
@Philippe Schenkel ,
If your emails to Verizon mailboxes are not bouncing and are landing in the spam folder for these mailboxes, this looks like a reputation issue.
I would recommend making sure your account is using a dedicated click tracking domain.
This will ensure the links in your templates align with your sender address and sending domain, this can sometimes make a noticeable difference for your sender reputation.
If you’d like to put this in place, simply create a ticket with our support team and they will be happy to enable this for your account. This is a free functionality.Once this is done, I’d suggest starting a warming period dedicated to these mailboxes, targeting your most engaged Verizon users and monitoring the results. With your dedicated click tracking domain set up, this should help you get back in the inbox folder soon.
