Up until this point, you&#8217;ve been failing \u2014 but since Gmail&#8217;s current policy has been not to penalize that failure, it&#8217;s <em>possible<\/em> it hasn&#8217;t been having a noticeable negative effect on your deliverability.<\/p>\n<p>If you&#8217;ve been seeing any DMARC-related blocks, it makes sense to turn this on.<\/p>\n<p>Also: If you&#8217;ve set up and verified whateveryourusernameis.gmusers.net at your SMTP provider, there&#8217;s a possibility you <em>might<\/em> see your email authenticated by whateveryourusernameis.gmusers.net rather than by your SMTP&#8217;s default signing domain (e.g., sendgrid.net). For instance, at SendGrid, that could happen if you&#8217;ve selected whateveryourusernameis.gmusers.net as your default domain under Sender Authentication &gt; Domain Authentication.<\/p>\n<p>In that case, you have two options. You might want to keep signing your emails via sendgrid.net for the time being, since it has an established reputation \u2014 if so, make sure whatever.gmusers.net is not the default domain at your SMTP provider. Or, option two, turn on domain replacement in the GMass settings to start passing DMARC.<\/p>\n<p><em>Why you might want to turn if off?\u00a0<\/em>The two reasons you might want domain replacement off are (1) you don&#8217;t want your shared domain showing up as your From address and you&#8217;re willing to risk failing DMARC for it or (2) you don&#8217;t want to change what&#8217;s already working.<\/p>\n<p>Again, this will all be moot once Gmail updates their DMARC policy to quarantine, but for now, it&#8217;s something some users might want to consider.<\/p>\n<h3>What we do if your Gmail address has a dot (.) in it<\/h3>\n<p>When we create your personal From domain and stand-in email address, we do use your Gmail username (everything before the @ in your address). You can see the examples in the screenshots above (samquick1992.gmuser.net and samquick1992@samquick1992.gmuser.net).<\/p>\n<p>However, there&#8217;s one case where we handle this slightly different, and <strong id=\"setup-instructions-i-dwta\">that&#8217;s if you have a dot (.) in your username<\/strong>. For instance, if your email address is cool.guy@gmail.com. In those cases, we do not use the dot in the subdomain, as a subdomain with four or more parts can look like spam and it&#8217;s definitely messier.<\/p>\n<p>So in those cases, your subdomain would be either coolguy.gmuser.net if you&#8217;re using our in-house server or coolguy.gmusers.net if you&#8217;re using your own third-party SMTP server. Your stand-in email address keeps the dot, so it would be cool.guy@coolguy.gmusers.net.<\/p>\n<h2>Setup Instructions If You\u2019re Using GMass\u2019s In-House SMTP Server<\/h2>\n<p>If you\u2019re using one of GMass\u2019s in-house SMTP servers (either our own SMTPGM server, or our Amazon SES account), there\u2019s pretty much <strong>nothing<\/strong>\u00a0you have to do to make this work.<\/p>\n<p><em>Wait\u2026 what are your in-house SMTP servers?<\/em>\u00a0GMass allows some users (those sending opt-in emails) to apply to use our SMTP servers rather than signing up for their own.
