Email going to Spam / low MailGenius Score

I’ve recently realized that my email is going to recipient’s spam folder. This is awful since I’m trying to run a business. There are 3 major issues specifically with Mango Mail:

1. The outbound mail server IP is missing a valid Reverse DNS (PTR) record matching the mail server domain. Could you please look into your IP routing and update the PTR record for this IP?
2. Reverse DNS of the Mail Server IP does not match the HELO command. Please update both the PTR record and HELO configuration for this outbound node so they align correctly.
3. My exact IP address is currently listed on 1 major blacklist. Could you please migrate my account to a clean outbound IP node or work with the postmaster to get this IP delisted?

Can someone please help me with these issues?

Thank You.
