How can I attach an audio file to an email and have it start to play as
soon as they open the email?
You can format your outbound email in one of three ways: plain text, rich
text, or HTML. With plain text or rich text, the sounds (MP3, AVI, etc.) are
usually sent as file attachments. With HTML you can imbed the sound files
directly in the body of the message so that they can be played automatically
when the message is opened or read.
The process to attach sound files varies based on your specific operating
system and email software. Also, the operating system and email software used
by the recipient will determine whether or not the sounds will be played when
the message is opened or read.
Many email programs are now blocking all file attachments by default,
especially sound or photo files, due to spam and viruses that have abused
these functions. Also, sound files tend to be fairly large so it is generally
best to avoid sending them via email.
An alternative is to post the sound files to a file sharing website like
myspace.com and then just email a link to the sounds which the recipient can
click on to listen or download as needed. This is generally the best method
as it increases the chance of your messages being delivered without being
blocked by anti-virus or spam software.
