Without DKIM setup for your domain, your sending domain will look like it's coming via one of tinyEmail's delivery domains.

Say your sender identity is [email protected]. If you set up DKIM with tinyEmail, instead of your emails showing something like the following, it will all be your domain.

Why does authenticating your domain matter?

DKIM authentication is how Internet Service Providers, (ISPs), like Google, Yahoo and Microsoft scan email for spam and spoofed addresses. Authenticated emails are less likely to be sent to spam or junk folders.

Spam filters and ISPs examine links in emails to decide if the email is trustworthy enough to deliver. By setting up DKIM authentication for your domain. you increase the chances of your emails landing in the inbox.

How to authenticate your domain with DKIM signing.

Authenticating your domain with tinyEmail is relatively simple and there are two main steps; set up the right records with your domain registrar and let us know so we can verify your settings.

Step 1: Set up your DKIM with your domain registrar.

To sign your email with tinyEmail by adding the following CNAME records to your DNS settings:

HOST: tec1._domainkey.YOURDOMAIN VALUE:
HOST: tec2._domainkey.YOURDOMAIN VALUE

Remember to replace YOURDOMAIN with your actual domain name without any http or https added.

Step 2: Get in touch with us to have your setup verified

Chat with us live from inside tinyEmail or send us an email to [email protected] to let us know that you have updated your records. We will then verify the settings from our end and if all looks good, you are good to go!

That's it, you have now authenticated your own domain as the sender of your emails. If you have a good domain reputation with ISPs, the likelihood of your emails landing in your subscriber inboxes should significantly improve.
