Allow duplicate email address


We have a list of subscribers where one email address could represent multiple subscribers.

And we want to send a personalized email to each of them, using that ONE duplicate email address.

how can we create subscribers with duplicate email addresses please ?

Kind reagrds,

each subscriber needs to have a unique email address, and you can only send one email per campaign to a confirmed subscriber.
So in the case that multiple users have one email address, it won’t let you add the second or later subscriber with the same email address as another subscriber
