In their own words
GlockApps
GlockApps helps marketers and businesses check email deliverability and investigate placement problems before sending campaigns. Inbox Insight shows whether test messages reach inboxes, spam folders, or subfolders at different providers, and checks them against SpamAssassin, Barracuda, Microsoft Exchange Online Protection, Proofpoint, and a Google filter. Reputation tools check IPs and domains against blocklists and report sender scores and placement by IP. Content analysis covers message size, images, and links, with an HTML compatibility checker. DMARC Analytics collects reports, tracks sending sources, and retains reports for a year. Uptime Monitor checks IPs, SPF, DKIM, DMARC, HTTP, TLS, and TCP, with checks configurable as often as every minute. The API supports automated testing, result retrieval, and client management by projects and folders on all plans, including free. GlockApps runs on the web and through an API. Its free plan includes two spam test credits; paid plans start at $59 a month, billed annually at $708.
Unspam.email
Unspam.email is an email deliverability platform for examining spam signals, sender authentication, blacklists, previews, and inbox placement. Spam tests assess authentication, sender reputation, blacklists, and message content, then show which checks affected the score. Inbox placement tests send a campaign to seed mailboxes at Gmail, Outlook, Yahoo, and other providers and report where it landed. Email previews cover rendering across more than 50 real clients and devices in light and dark modes. Scheduled tests can track placement and spam scores and send alerts by email when results decline. Its API has 39 endpoints across seven areas and can test mail sent through SES, Postmark, SendGrid, Mailgun, or a sender’s own SMTP setup; an MCP server lets compatible AI clients run tests and retrieve results. The free plan includes 21 tests per month, unlimited sender accounts, and 14-day data retention, but excludes DMARC monitoring and full API access. Custom costs $5 a month, with a $5 monthly minimum and pay-per-test rates.
