FAQ
Why switch away from GlockApps? Almost always price. You pay for an enterprise-grade feature set while using a handful of features. For GlockApps specifically, switching to mail-tester saves $1,020/year versus GlockApps's sticker price.
Are cheaper tools worse? For most users, no. The gap is usually in extras you may never touch — advanced permissions, dedicated account managers, or compliance certifications. Check the Cons under each pick to see exactly what is missing.
Can I switch back later? Yes — nothing here locks you in. Start on a free plan or trial, migrate at your own pace, and keep your current tool until you are confident.
