Once, a Stamp on the Envelope Was Enough

In the old analog world, we sent physical letters for more than 100 years based on a stamp with a value indicating the letter’s weight, size, and the physical distance the letter had to travel to reach the recipient.
At the post office, the stamp was marked with a postmark approving that the postage was correct, and the letter could be sent. If not, it would be returned or given penalty postage. Enough about that trip down memory lane.
Today, we send billions of emails daily, of all kinds and with varying content. The analogy is quite simple: these emails also need a “stamp” to reach the inbox on the other end. Today, these “stamps” are called SPF, DKIM, and DMARC. In short, these are identity and verification mechanisms that ensure your email is not classified as spam and thus reaches the recipient.
SMTP.dk has launched a tool you can use for free to check your email’s ability to reach the inbox. You simply copy the auto-generated email address into the email you want to check and then see the result in the browser window. There might be some things to fix to ensure optimal delivery.
