I received this from my hosting company, where they were referring to our (two-step) sign up process for newsletters, using your plugin…
“We are getting reports that your site is sending unwanted email correspondence. Each one of these reported messages causes harm to our email IP reputation and can cause delivery issues for our network. As a result we will need this issue to be corrected within 24 hours or your account will be suspended”
“All that has to be done is the email placed in a text box and the clicking of subscribe. This is not acceptable as Bots are using this to send your confirmation messages to users that do not want them.”
“The problem is that your site sent a email. This is what bots are abusing. You will need to configure your site in such a way that bots can not send emails by simply just putting in a email and clicking on subscribe. Captcha is a common method of doing this.
Hi, Newsletter already has an antibot system, check if it is disabled on subscription settings panel.
Have you recently sent a newsletter? And are you using the double opt in (see the subscription panel as well).
