Note: Verified 2026-11-11 from glockapps.com/pricing/monthly/bundle/, /pricing/annual/bundle/ (the default /pricing/ page shows annual), /pricing/monthly/spam-test-credit-packs/, /spam-testing/ and /inbox-email-tester/. Inbox Insight tests placement (Inbox, Spam or sub-folders) and scores mail against SpamAssassin, Barracuda, Microsoft Exchange Online Protection, Proofpoint and a Google filter. One spam-test credit is one email sent to the full or partial seed list; automatic tests also spend one credit each. A single subscription can test multiple domains and mailboxes. API access is listed on all plans, including Free. The free spam checker does not require an account; the Inbox Insight product page says no credit card is required, and the free-checker page says the first 2 Inbox Insight tests are free. HubSpot is listed as a supported ESP for mailbox integration (with Gmail, Google Workspace, Amazon, Mailgun, Sendgrid, Outlook, Mailjet, Klaviyo and Sparkpost); Salesforce is not listed there. Standalone DMARC Analytics plans billed monthly are Essential $55, Growth $95 and Enterprise $199; annual prices for those standalone plans were not verified today. High-volume and custom annual plans are sold through sales.
