I am using FastComet as a hosting provider and sometime back then started using SpamExperts to check emails going form their servers. After their implementation of SpamExperts I had to use SMTP and after that all my emails stopped going from my website. Recently, I got time to check around everything and did some research that how I can make my emails pass spam checks. Because right now my emails are being considered as spam. Although when I checked in various "Email testers" then the content is found to be spam free but, as soon as I added unsubscribe link then it showed email as spam.
So I finally, tested email from my hosting and sent an email both with and without using Unsubscribe link in them. And there it is, the email without the link reached to be just fine but the email with the link again stopped because of spam.
Is there a workaround for this? I also want to know how to add my address to email to make it more legit.
Note: In the above text, I am talking about mass emailing from Q2A. But, all my emails are stopped (even new member verification emails are stopped) so it's a dire situation right now and I need a fix for this.
