This is where you can find the number of messages Sent and Opened, for either the month or daily.
The Statistics Table shows Sent and Open numbers (top and bottom number on each row) for each message.
The Summary shows overall send and open rates.
Statistics is a total count for all shops. If you have multiple shops these totals will be for all. Though other menu selection items under SellerMail are specific to each individual shop, Statistics are for all.
Note: each individual message also has Sent and Opened statistics for that particular message. Click to edit any message under Messages to see the individual stats for that message.
