A: You can monitor up to 600 domains on Tier-3 of the Allarmia product. Each Tier-3 package includes 30 domain checker playbooks, and each playbook can hold up to 20 domains. This allows you to monitor SSL expiry and domain expiry for up to 600 domains in total.

If you need to monitor more than 600 domains, we also offer additional domain checker playbooks. I'd be happy to assist you with this for free as a special offer for AppSumo users.

Here’s an example of how you can set up multiple playbooks and domain status pages: https://allarmia.com/main/viewscreen/6_485634
