How to take care for content in envelope (call to action: put cd in computer, play the video)?

Follow these tips and help your envelope do its most important job: to get opened!
CHECK CD/DVD WORKING:
While sending the CD’s to companies, firstly you have to check while the CD is working properly or not
Check the disc surface before recording, and after recording check while the CD is working properly or not.
Remove dirt, fingerprints, smudges, and liquids by wiping with a clean cotton fabric in a straight line from the center of the disc toward the outer edge before packing them in envelop
Store discs upright (book style) in plastic cases specified for CDs and DVDs.
Use a non solvent-based felt-tip permanent marker to mark the label side of the disc.
For archiving recordable (R) discs, it is recommended to use discs that have a gold metal reflective layer.

ADD SOME COLOR:
Instead of the traditional pristine white envelopes typically used for business correspondence, make your envelopes more interesting by using color. Using colored envelopes would cost a bit more than the regular white ones, but it’ll be well worth the extra dollars if it means your envelope gets opened instead of being tossed to the junk mail pile.

CHANGE THE SIZE:
Similar to the impact of using colored envelopes, you can use an envelope that is anything but the standard #10 size. Go smaller with greeting card-sized envelopes, or go bigger to get to command immediate attention and stand out from that stack of mail.

USE HANDWRITING:
A handwritten name, contact details, email id on the envelope make it look personal, which increases the likelihood of it being opened. Using handwriting or equivalent would be a matter of discretion though, as some businesses would prefer to keep the overall look formal.

USE TEASER COPY:
Why not give your recipient a hint of what’s inside? Use a provocative statement. Rouse curiosity with a question or catchy headline that promises answers/details inside. Take teaser copy a step further with messages targeted at specific audiences by using phrases that speak about to your customers’ identity or interests. Envelopes can do more than just keep your material intact until it reaches your desired recipient.

It is getting increasingly hard to find computers with CD drives, and the best case scenario is that the corporate boss is going to ask someone lower in the rung to watch it and the chances of that happening is very low.
