Why Email Domain Authentication
Email Domain Authentication has a huge positive impact on your reputation as a sender and your email deliverability. It tells email providers that you are a real business and Zenler has your permission to send emails on your behalf. You are also explicitly showing your recipients that this email comes from you, so they are less likely to mark your mail as spam.
How to Authenticate Email Domain
Go to Site > Integrations and click on the button 'Email Domain Authentication' shown under Zenler Mail section.
If you are already added a Custom Domain, you can find the option to authenticate your email domain under Site > Site Settings > Custom Domain section also.
Clicking on the button, the Email Domain Authentication window will show up.
Click on the button 'Authenticate Your Domain'. A window Authenticate Your Domain will be shown.
Your Domain: Enter your email domain to authenticate here. While entering the domain name, you need NOT add www, http, https etc.
Use automated security: When this option is set as On, it generates 3 different CNAME records.
If this option is set as Off, it generates 1 MX record and 2 TXT records.
In a later step of setting up domain authentication, you can give these records to your DNS provider.
If your DNS provider does not accept underscores in CNAME records, you will have to turn this option OFF to use MX and TXT records.
When you click the Proceed button, the Verify Your Domain window will be shown up. You can see the records on the window. You can copy these records by clicking on the 'copy' icon near each record and add the same to your host's DNS section.
If you are not using automated security, the MX and TXT records will be shown on the Verify Your Domain window. You can copy and use the same in your host's DNS section.
After adding, set the option "I've added these records" ON and press the Verify button.
Note: Please wait and check back later as sometimes it may take several hours for us to be able to validate.
After the verification is done, you can see the details of the authenticated email domain under Site > Integrations > Zenler Mail.
The Remove button will remove the email domain authentication you have set up and revert back to default Zenler Mail sender authentication.
Note: If you have multiple sites, only one Zenler Mail is supported per account. I.e at the moment you can authenticate only one email domain across all your sites.
