As the code used for html emails is still quite basic, so that all possible email programs can read them well, and I did not want to risk using a javascript based obfuscator I had to use the mailto syntax when usually.
The MailTo command can do more than enter a single e-mail address in the “Send To” field while activating your e-mail program.
Address message to multiple recipients
, (comma separating e-mail addresses)
Add entry in the “Subject” field
subject=Subject Field Text
Add entry in the “Copy To” or “CC” field
