Our verdict
A dependable inbox placement and spam testing tool for deliverability checks.

Not the right fit
Teams wanting full sending infrastructure.

Strengths

Watch-outs

- Test credits go quickly at high volume
Pricing
Free trial, then monthly plans by test volume.
Pricing summarised in October 2026 and not re-checked since. Vendors change plans often, so confirm current pricing with GlockApps before you budget.
Security and governance
Sending infrastructure holds domain and mailbox credentials. Keep domains in your own registrar account where possible, use strong admin controls, and follow sender requirements from Google, Microsoft and Yahoo on authentication and complaint rates.
How we would roll it out
- Buy separate sending domainsNever risk your main company domain.
- Set up SPF, DKIM and DMARCAnd warm mailboxes before any campaign.
- Monitor placement weeklyPause inboxes that land in spam.
