That one website that checks if your emails will land in spam

Why it's the pick

Mail-tester gives you a one-time address: send it your real email or newsletter and it scores it out of 10, flagging missing SPF, DKIM or DMARC records, blocklisted servers and spammy content. Three tests a day are free with no account; more cost a small fee.
