Hello -
Check the domain with MXToolbox if you haven't all ready - it's not
impossible that the domain or servers are on a blacklist.
Also check that SPF and DKIM/DMARC records are good and set up for your
sending service and that reverse lookups are correct.
Reputation in this case applies to email and not the standing of the
domain, site or another considerations like that. It could be something
as simple as Gmail not being used to seeing a large amount of mail from
the sending servers - keeping a low level of traffic passing through
them seems to improve reputation.

Hello! Long time no see. I have a customer whose email campaign was
heavily blocked yesterday by Gmail with the error:

message is suspicious due to the very low reputation of the

I would love to speak to someone at Gmail about this because I don't
think the customer should have a very low reputation. Of course, I
could be wrong, and Gmail is seeing something I'm not seeing. The
customer has double opt-in, low complaints, good opens, lots of
purchases, and an active social media presence with a lot of
followers/fans. I think the issue is that they only send every couple
of months. They are a fashion retailer that announces their upcoming
event via email (the email we saw blocked) and their inventory sells
out during the event.
If someone could reach out to me, I'd greatly appreciate it. I'm not
sure what to advise this customer except to say that email may not
work for their business model.
Thx!
