Yes. Mailendy InboxCheck is a free email checking tool designed to help you review your email subject line and body before sending.
Does this tool guarantee inbox placement?

This version focuses on email subject and body analysis. A future Mailendy tool will check SPF, DKIM, DMARC, MX records, and domain deliverability setup.
