How to fix subject line getting encoded in Sendgrid email subject line

Just spent an hour on this making sure there were no random encoding anywhere on OddsRabbit's backend on newsletter subject lines (we're currently using SendGrid).

Finally found the fix, if you're using dynamic templates, make sure you use triple curly brackets in the dynamic template's subject line ex. {{{subject}}}

This will prevent SendGrid from automatically encoding your subject line.
