There are two changes we recommend when email from your domain is being identified by spam and ending up in your recipient's junk mail folder.
First we need to make your SPF record strict. To do this: login to your cPanel, then click on Email Deliverability, then click on Manage next to your domain name, under the SPF click on CUSTOMIZE, scroll to the bottom and check the final checkbox, titled "Use the “-all” Entry", and finally click on the INSTALL CUSTOMIZED SPF RECORD button.
Next we need to add a DMARC record. To do this: login to your cPanel, then click on Zone Editor, then click on Manage next domain, then click the down arrow to the right of + Add Record, select Add "DMARC" Record, select Reject for the Policy, then click OPTIONAL PARAMETERS, select Reject for the Subdomain Policy, select STRICT for DKIM Mode, and select STRICT for SPF Mode, then click ADD RECORD.
This should improve email delivery and help prevent misidentification as spam.
