Send welcome email after confirmation

Hi there.
I have to explicitly renew the confirmation to my newsletter, due to new rules imposed by GDPR.

I can set all my users as “unconfirmed” and send them a newsletter with the confirmation link inside (this is the easy part).

I want to encourage the confirmation, offering a discount coude on my articles, so I need to send them the confirmation email again (with the voucher inside).

Problem! It seems like the confirmation email is sent only to new subscribers and not to the renewing ones!

Can I force the standard behaviour??
