Yes, I'm following the opening of my outgoing emails ...
I notice that the number of openings has also decreased significantly.
In addition, Gmail often transfers my messages to spam (I send them from MS Outlook, and I use a professional email address).
Spam flag: Send email to various different people at Gmail, people you know, and let them know and ask them to flag them at not spam. With some luck you might get better results.
Otherwise, unfortunately if you send many emails /outbound, Gmail will eventually flag them anyway.
Regarding market: 2021 is still weird so far, in my opinion. Was looking at last month's sales report post, 4-fig sales seem to be low and in small value to me. While 5-figs and more are pretty much booming.
Corona: Offtopic somehow, but please take this into account as well. I took the shot as well (second coming soon) BUT I don't think this will fix the problem. Even if everyone else in the more wealthy part of the world does, a rampant situation like India will eventually spread all over the world fast - because the changes will become so fast that our vaccines can't keep up. Also antivax is growing.
Sorry for the bad perspective but I've been personally researching this a lot and we're still on track to the same situation as with Spanish flu, except slowed down by vaccine. Whoever doesn't understand what's going on
exactly, has to look at science and history (edit: real, not viewed through politician's lenses as seen on TV), preferably both.
We've been sold a fast solution via vaccines but in practice, while good for personal health, from the economic viewpoint it's only a false hope that our governments have sold us.
Keep calm though, and carry on domaining.
