Selzy

Pros:
- simple configuration
- many email templates
- letterhead supports unicode

Cons:
- Page loading is too slow
- WP plugin doesn't work, installing the second website doesn't even appear
- The configuration process is still complicated, embedding the code from selzy shows up, but when trying to subscribers, it says a campaign is missing. After installing the campaign, go back to configuring the form. But still error.
- After completing the campaign, there is still an error that the user cannot register, but it is not allowed to fix it, it can only be copied for duplication
- Complicated email configuration instructions, no instructions when sending emails from subdomains
- Cannot change domain name after user subscrib., after entering email, still points to selzy domain name

In short, there should be a list of required steps right on the Dashboard, avoiding having to go around many steps.

If possible, pls integration add GoZen Forms.Ai & OpenForm

P/s: I've spent 4~5 hours configuring it, but it's still not done, the page is slow + the process is very circular!
