Hi @Joseph Morgan! When you say you’ve used Klaviyo for 3 days, what exactly does that mean? Is your domain also new (<90 days old)? Were you using a different email marketing software prior on the same domain, and if so, for how long?

We have the same issue. 
Our emails bounce and the error message we receive is:
“The sending IP is listed on https://spamrl.com/. Please resolve this and retry.”

I checked and saw the IP is on 5 blacklists. We deliver our digital products via Klaviyo emails and lately we’ve been receiving more and more complains of users not receiving their digital products and when I check why it because they bounced because of blacklisted IPs. 

Is there a way to resolve this issue? 

On a shared IP pool, your account will be sending from a variety of different IP addresses within the pool of IPs shared amongt other senders. Because of this, third-party tools such as Google Postmaster will evaluate the IP reputation based on all the IPs in the pool, including ones that are on a blocklist that may not be in use. To put it another way, these tools deem the entire bunch of apples as “bad” because one apple in the bunch may be rotten.

It’s also important to note that inbox providers pay much closer attention to the sending domain reputation versus the sender IP reputation. Because of this, tools such as Google Postmaster are great at helping to identify or catch potential deliverability issues, but they don’t do a great job conveying the larger picture at the actual cause of these issues.

Klaviyo continually monitors our IPs on a number of blocklist providers and frequently have them de-listed. That said, IPs being blocklisted are not uncommon. This has to do with how widely available blocklist providers are and because of this, typically holds no impact on one’s deliverability.

I am still seeing people complain about this same problem for new accounts in social forums. Some tools I’ve used before have strict policies about spam so their shared IPs stay clean. Does Klaviyo do anything on its end to update or monitor their IPs? If a few bad apples spoil the whole bunch, that’s bad news for everyone.
