Yes, we have a free plan. You can create a free account and run 3 email tests to try the service. We will also give you 10 000 credits for DMARC Analytics. You can activate this tool in your account, publish our DMARC record in the domain’s DNS, and collect DMARC reports. DMARC reports will tell you if the messages sent by your legal sources are authenticated and show email authentication issues that you must fix.
If you want to continue testing your messages and sender reputation with GlockApps after free credits are used, you must subscribe to a paid plan. You can see all our plans and prices here.
