Frequently asked questions
Is GlockApps free?
Yes, GlockApps has a free plan with 2 spam test credits per month and 10,000 DMARC messages per month. Paid plans start at $59/month (billed annually).
What does 1 spam test credit cover?
One spam test sends your email to GlockApps' seed list (115+ addresses) and returns placement results across all providers in a single report.
Can I use the same subscription for multiple domains?
The $59 Essential plan supports only 1 sending account. You must upgrade to Growth ($99/month) for 10 sending accounts or Enterprise ($129/month) for 20 accounts.
Do my unused credits roll over?
No. Unused test credits expire at the end of each month with no rollover, which users report as a frustrating design choice.
Is GlockApps good for cold email?
Not ideal. GlockApps uses seed lists designed for newsletters, not one-to-one cold outreach patterns. Users report seed results don't translate well to cold email sequences.
