There's a lot of ignorance out there from marketers and IT professionals when it comes to email deliverability and inbox placement. Most companies simply believe it's a simple process where by you send the email… and it gets where it needs to be. It doesn't work that way – internet service providers have a number of tools at their disposal to verify the source of the email and validate it as a reputable source before that email is ever delivered to the inbox.

We've been amazed at the improvement in our deliverability, inbox placement, and subsequent performance of our own email strategies since utilizing 250ok inbox placement monitoring, blacklist monitoring and troubleshooting tools. That's related directly to a far improved return on investment of our email marketing program.

What is Email Authentication?

Email authentication is the process by which internet service providers (ISPs) ensure emails are really from the rightful sender. It confirms that the email message itself hasn't been modified, hacked or forged on its journey from the source to the recipient. Emails that are not authenticated will often end up in the recipient's spam folder. Email authentication improves your ability to have your emails delivered to the inbox rather than the junk folder.

Ensuring you have DKIM, DMARC and SPF records properly deployed can vastly improve your inbox placement – resulting directly in more business. With Gmail alone, it can be the difference between a 0% inbox placement and a 100% inbox placement!
