Tools for the part of outreach that happens before you send

Free, with no signup and no email required to see a result. The site earns a commission when someone starts a lemlist trial through one of our links, and that is what pays for building them. The model only works if the free thing stands on its own, so the checker will tell you your setup is fine and you need to buy nothing, when that is the honest answer.

The deliverability report card. It reads your live DNS and grades what is actually published, so you find out whether the problem is your configuration before you spend a month rewriting copy. Once authentication passes, the warm-up calculator gives you the ramp schedule for lifting volume without tripping a filter.

Scope, not accuracy. The report card audits every record that affects delivery and grades the domain A to F. Each single-record checker answers one question, such as whether your SPF is valid or your DMARC policy is set to anything meaningful, and shows only that result. Use a checker while you are fixing one record and want a quick confirmation. Use the report card when you want to know where the domain stands overall.

Yes. Everything these tools read is published in public DNS, so a domain you do not control resolves for us exactly as it does for anyone else. Running a check on a prospect before a conversation about their sending setup is a legitimate use, and a fairly common one.

It makes you eligible for the inbox, which is a smaller promise than it sounds. Authentication decides whether a mailbox provider can verify who sent a message. Reputation, list quality, and content decide what it then does with it. A domain that passes SPF, DKIM, and DMARC and still lands in spam has a reputation problem or a list problem, and the guides are where that half is covered.
