about email not exist

Hi, if you configure a return path on Newsletter’s main setting, you should receive notifications about delivery errors and then delete those emails. Professional delivery services manage that feedback in a more automated ways if you send with their SMTP/API services.

i dont understand could you plese explain to me more

should i use plugin” wp_mail return-path ” then what ??

The return path can be set on Newsletter’s main settings, then, on that email address you should receive the delivery error notifications. You can check them one by one and delete the failing subscribed addresses. This is for manual handling of the unusable addresses. Automatic methods need the use of the bounce addon (see the plugin site) or professional delivery services (Amazon SES, Mailget, Sendgrid, …).

Manual handling is ok if you have a few subscribers: after the first clean up you shouldn’t receive many more notifications.

please explain to me how can i do return path from main settings

send to me video of images or stpes one by one to do this please

On Newsletter’s main settings there is the “return path” setting in the same tab of the sender email address: set there a valid email address.
