How to use them
Start with the domain. Without correct SPF, DKIM and DMARC records even good copy lands in spam, so the DNS checker comes first. Then paste the first email of your sequence into the spam checker and fix what it flags. Leave the calculator for last: it answers how much you can pay for a lead for outbound to pay off, not what a lead costs.
None of the tools stores what you enter. You leave a work email only when you want the full report or the fix instructions.
