I'm with a doubt and I dont find reliable information about this, so I came here to ask you.
I'm using phpmailer class to send emails, and everything is working fine.
But I wanted to avoid that emails dont go to spam folder.
So I found some people saying if we use date in our message, avoid this.
This technique really works? And if yes, is really necessary? Even using phpmailer?
I'm asking this that because I think that all email providers, in every email, appears the date, so I think a bit repetitive to put also date in my email message.
Something Like this:
<p>Email sent at '.date('d/m/Y H:i:s').'</p>
