My emails are going to recipients’ spam
I use my PM address for work and have been notified that many of the emails I’m sending are going to recipients’ spam. This seems to be a problem when I email big organisations running MS enterprise. Gmail and Gsuite recipients are fine.
I know that recipients can mark my emails as safe and that should help train their servers, but the problem is persisting. Is there anything I can do on my end to prevent this?
