InboxTrue ranks #4 of 47 for “inbox” in ChatGPT directory search, behind Inbox Monster at #1. For “verification” it's #35 of 49 and Easy Email Verification leads. It doesn't show up for “notification”, where Mailopoly Inbox ranks #4.
InboxTrue checks whether an email address can actually receive mail before you send to it. It inspects the address's domain and talks to its mail server, then reports a clear verdict: valid, maybe valid, invalid, ambiguous, or a temporary or permanent error, with a retry hint when a server asks us to try again later.From the plugin’s directory listing
