Comparison
DeliverSight vs GlockApps
Similar bundles — spam testing, DMARC aggregation, reputation and uptime monitoring — at very different prices. DeliverSight starts at roughly a third of GlockApps’ entry plan, puts API access on the mid tier rather than reserving it, monitors certificates and MTA-STS as well as records, and keeps all data in the EU.
GlockApps details checked 2026-07-29 against their own published pricing. We have not linked to them; the figures are here so you do not have to go looking.
Why teams pick DeliverSight
- Entry price is roughly a third of theirs for the monitoring-and-DMARC use case.
- Monitoring goes wider than DNS records: certificates, MTA-STS, TLS-RPT, nameserver and RDAP changes.
- API access on the mid tier rather than the top one.
- A genuinely usable free tier with no account required for a one-off test.
- EU-only data: the controller is an Estonian company and the infrastructure is in Finland, so submitted message content never leaves the EEA.

Choose DeliverSight if…
You want authentication, reputation, content and DMARC covered with monitoring and alerts, without paying for placement testing you would not use — and you would rather your customers’ message content stayed in the EU.
Check it against your own mail
Our free tier is 3 tests a day with no account and no card, which is enough to judge the report depth and set a domain up for monitoring before you decide anything. If it turns out you specifically need folder-level placement data, you will know quickly — and so will your budget, at three times the entry price.
