- Message envelope - the friendly-from and reply-to addresses
The message envelope includes only the MAIL FROM: and RCPT TO: (RFC x21) SMTP addresses, not the From: and Reply-To: headers (RFC x22).
David,
I recently did some work for a client that showed that while they were getting circa 20% open rates it was pretty much always the same people opening the emails (we did this by analysing across about 3 months of email sends). Of their 50k emailable base, the reality is that only about 10k were even vaguely engaged. This has now lead to a pretty significant piece of work around cross channel re-engagement (combination of in store, web, social, SMS etc.)
So, there are a few things to consider:
Best of luck getting the rates up.
Regards
Jo
