Good technical checks

4.30

The SPF/DKIM/DMARC validation is very useful, though the design of the tool could be more modern. Functionally, it’s excellent.

Reliable but a bit slow

4.20

The analysis works great, but sometimes the tool takes a while to process larger campaigns. Still worth it for the insights.
