What this means for your email list
Is a free-provider address a problem?
Addresses at emailondeck.com are legitimate and deliverable in general. What goes wrong is the mailbox part before the @: typos, old accounts and abandoned inboxes. That is what per-address verification catches.
Sender authentication
emailondeck.com has no DMARC policy, so receivers have no instruction on what to do with mail that fails authentication. Large mailbox providers now expect bulk senders to publish one.
