Mailmark launched 6 months ago as a cold email tool. This relaunch is a rebuild around a different job: running email for every product you ship. Each product's domain gets guided DNS setup and hourly re-checks, unlimited mailboxes, and a shared Gmail-like inbox. Send product update campaigns to your users, or send from code with the REST API and npm SDK. New: recipient verification before every send, bounce protection, and SPF/DKIM/DMARC and blacklist monitoring.
