PRINT OUT THE EMAIL THAT HAS YOUR DTV VISA.
That's what you should do... print it out.
You may have to show PROOF of your DTV Visa to airline staff on check-in for your flight βοΈ to Thailand...even to the connecting airline staff.
Upon arrival into Thailand, show the DTV visa to the Thai Immigration Officer and look at the STAMP placed in your passport to be sure you are STAMPED in for 180 days.
