I have recently launched a new website and now I'm having a problem with gmail blocking all email sent from my website. I'm not sending spam, just confirmation emails to the users who post on my website. The emails are specifically blocked because they have html and links (I know because I tried to send plain text emails and they were delivered successfully). Unfortunately, using plain text is not an option for the confirmation emails.
Any suggestions on how to avoid gmail spam filters that blindly block my emails?
