They do this, we do not
- Inbox-placement tests, content spam checks, and contact verification are in the plans. InboxMonitor does none of those.
- Spamhaus Intelligence credits appear on Pro, Business, and Agencies. InboxMonitor does not query Spamhaus unless a paid key is configured.
- The free plan includes weekly authentication and blacklist checks for one domain.
We do this, they do not
- Checks run daily, not weekly.
- The result is one score with the finding that moved it, including PTR and domain age.
- InboxRescue is a separate one-time report. EmailGuard's page also offers setup help; the two are different products.
Questions
Is InboxMonitor an EmailGuard alternative?
Only for scheduled SPF, DKIM, DMARC, and blacklist checks. EmailGuard also sells placement tests, content checks, and contact verification, which InboxMonitor does not do.
Can I use both?
Yes. EmailGuard can run a placement test and a content check. InboxMonitor can watch the DNS record every day and email you if PSBL or 0spam lists an address it checks.
How is pricing different?
EmailGuard's free plan is one domain, and Pro is $49 a month for 25 domains. InboxMonitor's free plan is 3 domains, and Starter is $39 a month or $390 a year for 25 domains. The paid trial is 14 days and does not need a card.
