@Heinz Veintimilla thanks, but it seems like that it is only for email, right? Also I’m not sure regarding cold emailing , I have a website and I get a lot of cold emails from others asking some short questions like “do you deliver to USA , Canada” or similar to this. Majority if not all, has ended up in my spam so far. How is this sufficient? There is so many in the spam. When I got the email in my inbox I blocked and reported as spam , did that make Gmail recognise these emails as spam ? How do you guys go around this?
