There is no way to recall messages sent from SFMC - nor really from any ESP. Even the 'recall' options in Outlook, etc. are very flimsy as they only work depending on many variables with the default being failure of recall.
This is a great quote (It is about Marketo, but is definitely relevant for SFMC as well) for why this is so difficult/not possible:
There are a few reasons why this isn't very feasible. Let's start with
stating the obvious, that an email is really just a text file shipped
from one ESP to another, routed to your user account and stored there.
The emails are received regardless of who they're from - there's no
middle-ware gatekeeping the email from shipping from one box to
Once it arrives, the ESP chooses what to do with it: deliver, block,
or move to a folder (ex: Spam). There's some validation done to see if
it's really from that sender (DKIM, DCAR) but in reality most emails
are received unless the IP sending it is blocked.
Now you have the email somewhere in your email program, be it an
inbox, spam folder, etc. Most email programs then take the step of
downloading it to your device so you have it for off-line reading.
This is one MAJOR barrier to recalling. You can recall, but I'm on a
plane not connected to internet. I'm going to receive that message.
Another reason is that, as you know, anyone can say that an email is
from anyone else. Any one of us here could quite easily send, for
example, your mom an email from your email address and she'd be none
the wiser. Because there's no REAL credential matching and because
Marketo is often used to send emails from different email addresses,
there's no way to know that the request to delete the email is real.
For such technology to work, you'd need a way to verify to my email
service provider that you delivered the email and that you want to
delete it. As stated earlier, an email is nothing more than a text
file delivered from one IP address to another and in many cases a
person can switch IP addresses at any point in a day so there's no way
to certify that you're authorized to delete it.
Now, these two come down to a MAJOR security no-no, which is
authorizing a system to remotely delete files from a device without
authorization. If technology existed (and I'm not saying it
doesn't...) that would allow me to access storage on your phone and
choose to delete a file without your consent then what's to stop the
Evil Russian Hackersfrom accessing other files and deleting or
In reality, it's very much similar to postal mail. If you accidentally
send me a blank check for $10,000 that you meant to send to someone
else, you don't exactly have permission to break into my house and
take it back, nor am I obligated by anything other than my morals and
scruples to return it to you upon request.
