What MailMonitor is
MailMonitor is an email deliverability service for diagnosing and monitoring whether messages reach inboxes. Its placement tracking covers 400+ real inboxes across more than 90 ISPs, and it includes inbox placement, sender reputation, authentication, blocklist, and spam trap monitoring. The Deliverability Foundation plan includes an email authentication audit and blocklist monitoring. The Strategic Partnership plan adds an in-depth deliverability audit and 24/7 reputation monitoring. MailMonitor says it works with all email service providers, including Mailchimp, Sendgrid, Marketo, HubSpot, and Klaviyo. Its REST API provides programmatic access to data shown in the user interface; API access must be enabled for the account. Support varies by plan: Foundation includes analytics assistance by ticket, Strategic Partnership includes priority support access, and Enterprise includes chat communication with the team. The listed annual plan prices are $1,000 a year for The Deliverability Foundation, $2,000 a year for The Strategic Partnership, and $3,000 a year for Custom Enterprise Solution. MailMonitor is available on the web and through an API. The company says it has operated since 2010 and is based in Salem, New Hampshire.
