Where is the record of Email --send now (50 or less)
Using the "quick email" function (aka "send now to 50 or less") bypasses CiviMail - so they won't show up on CiviMail reports.  If you need CiviMail functionality (e.g. reply/click-through tracking, reporting, reuse, scheduled emails, etc.) you must use CiviMail.

However, you can still pull up a record of these emails, either via Advanced Search or Activity Report.

Advanced Search


Search menu » Advanced Search.
In the "Activities" section, specify "Email" as the Activity Type, and some way of identifying the email in question - perhaps the subject line (see screenshot), or the date.
