I just tried to send a message to VAST support multiple times and got this in response from Google:

This message was created automatically by mail delivery software.

Hi Joachim,

How are you sending this? What is your email client and version?

We have in recent months updated our DNS records for GSuite to use DMARC and DKIM.
In fact there is a thread here about it because Google turned on some new stuff that was flagging our emails everytime we did a forum post

Just FYI,

Others have been sending in support cases today and I just sent a test support case message and received it.

Sounds like your email client, but if you give me the details I would be happy to help if I can

I'm using Thunderbird 60.6.1 (64-Bit) on a Mac with Mojave.

The mail included a few screenshots, but the error message doesn't really indicate my mail was flagged as spam or such...

I've communicated with Mariano using the same mailer and address just two or three days ago...

Are you able to try it from a web-based client?

turns out this is most likely missing an SPF record on our domains, not a problem on Instantiations' side. Recorda are updated, will see tomorrow or the day after if it solves the problem.

The problem occured first with mails to Instantiations, but in the meantime I found out I cannot send mails to anybody on gmail. Which hasn't been the case just a few days ago.

Yes, Instantiations had similar troubles recently as gmail was marking our emails from this forum with big “could be spam” warning messages. And we had to start adding all these new DNS records for dmarc/dkim/spf. Furthermore, any other service that sends mail from instantiations must also be included in the dns record.
I very nearly sent out our update letter recently which would have ended up in everybody’s spam bucket had I not added Mailchimp to the dns records. I had to do the same for FogBugz
