Unsubscribed user is not getting resubscribed although shown to him

[fussel132]

Version:

• listmonk: v2.4.0
• OS: Docker on Debian

Description of the bug and steps to reproduce:

1. Create a new list (I chose "public" and "double opt-in", but also happens on "single opt-in")
2. A user subscribes and confirms the subscription by mail
3. After sending a campaign, the user might decide to unsubscribe. If he does, he gets marked as unsubscribed (as intended)
4. If he now tries to opt back into an unsubscribed campaign, he will be presented a "subscription successful" screen (no matter if single or double opt-in) although he won't receive any mails as he is still shown as "unsubscribed" in the admin panel. The only way to opt-in is to manually remove him from those campaigns in the admin panel.

I found a similar issue #588 which described the same issue

That's rather inconvenient. Also I noticed, those admin confirmation mails as well as the "double opt-in" confirmation mail use a template where the site's logo is displayed up top which in my case doesn't look very well. Is there any way to edit those templates?

Thanks in advance,
