In the same way you show someone your ID card to prove you are who you say you are, domain authentication is a way to let the email providers (Gmail, Outlook, etc.) know that it’s you sending emails from your address.
The process to authenticate your domain is not super technical, but it requires that you know where you bought or registered your domain address (your URL). These are companies like GoDaddy, Bluehost and WordPress.
Once you know where your domain is registered, you’ll need to provide them with two important pieces of information that you can get from your MailerLite account:
Sender Policy Framework (SPF) - Gives your email marketing tool (MailerLite) permission to send email messages on your behalf and confirms that you are the owner of the domain’s email address.
Domain Keys Identified Mail (DKIM) - Ensures that the content in your newsletters was not changed during the sending process.
Here is a quick video tutorial on where to find these two items (SPF and DKIM) within MailerLite so you can provide them to your domain company.
If you have not authenticated your domain, you should make it a priority. Spammers will often attempt an “email spoof”, where they take control of your domain to send unauthorized emails. This would damage your domain reputation and hurt email deliverability rates.
The good news is that you only need to authenticate your domain once, and you are all set to send emails from your address with a verified domain.
If you have any trouble, here are several more resources to help you authenticate your domain using MailerLite.
