 * Hi, is there a way to block unreal emails or Certified Emails from being inserted
   into the field of the emails?
 * for example block gmail.it or glail.com or other stuff giving error to the mail
   server, and in italy we have also certified emails like pec.it that are not normal
   emails and they give erorr to the smtp server, and when the errors are many the
   smtp server is blocking also all other emails for a while..
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fblock-wrong-emails%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hello Matteo,
 * you can simply use 2-step subscription and the whole problem will be solved.

 * Yes, but for the 2 step subscription, I still have to send an email and if many
   emails are wrong, my mail server get blocked, so if someone want to make a bad
   joke to all the newsletter plugin users, is enough that he subscribe few false
   dozen emails and they all get the email server blocked probably for a while, 
   caused from multiple wrong emails sent from the mail server..

 * Hello Matteo,
 * if those are spam submissions, a captcha may help in mitigating the issue. If
   those are real submissions, it is highly unlikely that there would be a high 
   number of non existent or incorrect addresses that would block your sending capabilities.
   Anyway, take a look [here](https://www.thenewsletterplugin.com/documentation/subscription/antiflood/)
   to check which tools Newsletter offers to help you with these spam issues.
 * Thanks, 
   Michael
