MxToolbox Inbox Placement
What MxToolbox Inbox Placement is
MxToolbox Inbox Placement checks whether email reaches the inbox, lands in Spam or Junk, or goes undelivered at major providers. It is part of MxToolbox Delivery Center and is accessed through a Delivery Center plan, not as a standalone subscription. It works with any email sending system; named examples include HubSpot, Mailchimp, Marketo, and Salesforce. Users can run pre-send tests to a seed list or add test inboxes to active mailing lists for continuous monitoring.
Analysis covers spam-like patterns, image counts, link issues, unsubscribe compliance, and email rendering across clients. It also checks SPF, DKIM, and DMARC configuration and compliance using headers and DNS records, tests Google, Microsoft, and Yahoo bulk sender requirements, and checks domain and IP blacklist issues. Delivery Center costs $129 a month, billed monthly, for 30 analyses per month, five domains, and 500,000 email messages. Delivery Center Plus costs $399 a month, billed monthly, for 100 analyses, five domains, and 5,000,000 messages. There is no free plan or free trial.
