I’ve used a bunch of these tools when setting up client campaigns and cold outreach sequences. Testing SPF and DKIM records especially can get confusing, so having these tools to confirm things are configured right saves a lot of headaches. Sometimes even one small error can mess up deliverability big time.
Lately I’ve been using an email verifier website that gives me a quick idea of which addresses are risky or fake before sending out anything. It’s made a big difference in bounce rates and open rates for me.
