Subscribe functionality from Casper theme not consistently working: "Please enter a valid email address!"

Looks like someone had a very similar issue here and solved it by ensuring their mail configuration is setup correctly:

Local Ghost 3.0 - subscribing does not work

There is no email provider setup, the blog sends emails “Direct”-ly. It worked for a @gmail.com address (it also works for the blog’s domain), but it doesn’t work for a @hotmail.com address. The blog’s email address is the domain’s address, meaning @secareanu.ro. Emails usually end up in spam, even though the DO droplet has a fixed ip.

Local Ghost 3.0 - subscribing does not work

I’ve done the AWS SES/SMTP setup and now it seems that the subscriptions work fine (at least there is no more error message about invalid email address, need to check if it sends the confirmation messages). Yes, it works now.
