Did you read the link? Does your ESP have a postmaster account? If they don't send
enough messages ("a large volume") to Gmail they won't provide any information
about reputation, except that that itself indicates that you haven't (and can't) collect
enough reputation to be other than low aka poor. SORBS certainly doesn't like that IP
address.

Mark,
The PTR record (and matching FCrDNS) clearly shows that this is an
official Shopify sending IP. Any system that blocks these, with rare
exception, probably isn't very smart? ...or doesn't mind having many
egregious false positives, where users see legit/desired messages in the
spam folder? And I don't totally fault the SORBS listing because SORBS
is purposely very aggressive, and that is why most spam filters that use
SORBS - only use it for adding a point or two to a scoring system, such
as SpamAssassin - and SORBS is very beneficial when used that way! But
blocking these based on some spams getting through Shopify, or based on
a SORBS listing - isn't very smart.
The bottom line is that Google appears to be doing horrible spam
filtering in this particular instance. Meanwhile, you should take a look
at Christine Borgia's resume at LinkedIn. For just one example, she was
THE Postmaster at AOL for several years.

So I think she knows/understands much more than what you give her credit
for - and here's the thing - even if what you said about "collect enough
information" is true - it's just not very smart for the spam filter of a
hosting platform THIS large to treat such an IP as an "island" - without
somewhat factoring in the other IPs which share common domains at the
end of the PTR records (which pass FCrDNS and where they dynamic PTR
records). In other words, a smarter system would factor into their
analysis of one single legit Shopify outbound IP, the behavior/history
of other IPs from this SAME sender, but of course not going too far with
that, since an occasional individual IP can get severely compromised.
So, in this case, it certainly APPEARS that Google did NONE of that
factoring in of other Shopify sending IPs, and treated this like an
island?
Also, even if it could be shown that a shopify user was sending some
spam out of that IP, unless that was an egregious situation - this is by
far most likely a stupid Google spam-filtering mistake that's causing
many legit/desired emails to be blocked, with probably far more such
blockage of legit/desired emails than any spam this is blocking, if any.
Quite frankly, I'm constantly amazed at how often I see assumptions from
so many - that assume Google is always right and the other entity is
wrong - even when all the facts point to the opposite.
