It does not accept & in email address

As far as I understood you want to add a subscriber that contains the & symbol as part of the email address?!

Ah yes, I think that is called a subscriber in Enlish.
addresses like jan&piet @ website.nl
(without the spaces)

Ah okay! We’ll take a look and get back to you soon on that.

Any news?

Hi Elja,

Sorry for the delay. We’ve run some tests and this character is accepted on our subscriptions forms.

Please get in touch with us here: https://support.mailpoet.com so that we can ask you specific and private details, okay?!
