IncrediMail
IncrediMail is an email client which produces multimedia e-mail.Its free ad-supported version is available for download at its website. The paid version, IncrediMail Premium, removes its advertisements.
The product is intended to be user-friendly, and it employs a Graphical User Interface and multiple templates. The program offers both audio and video embedding in e-mail messages.
IncrediMail-authored e-mails do not require the program to exist on recipient machines, but the e-mail servers do need to enable the Incredimail formats.
The program increases message sizes (and consequently download times for recipients) and uses more bandwidth than text-only or HTML mail. Therefore, some people find use of programs such as this annoying and the features employed by them as so many geegaws.
