Problem: When creating announcements and checking the “send email” box, the resulting email message body may contain HTML tags. This has been confirmed to occur when using “Smart Text” with the text editor off, but may happen with the visual editor as well.
Solution: There is no solution available at this time, however Bb has indicated that this is resolved in a future release. The workaround is currently to avoid using HTML formatting where possible when creating announcements that need to be sent as emails.
