Step 1 - Use SPF record to help with Revamp CRM email deliverability
The purpose of an SPF record is to detect and prevent spammers from sending messages with forged From addresses on your domain.
Why are SPF records important?
Adding an SPF record can help prevent others from spoofing your domain. You can specify which mail servers are permitted to send email on behalf of your domain. Then, when incoming mail servers receive email messages from your domain name, they compare the SPF record to the outgoing mail server information. If the information doesn't match, they identify the email message as unauthorized, and will generally filter it as spam or reject it. So this will make sure your emails go straight to the inbox.

Step 2 - Use DKIM (Optional)
Domain Keys Identified Mail (DKIM) allows senders to associate a domain name with an email message, thus vouching for its authenticity. DKIM uses “public key cryptography” to verify that an email message was sent from an authorized mail server, in order to detect forgery and to prevent delivery of harmful email like spam.
