Is there any free email providers?

[heart2hack]

Hello.
My server IP is blacklisted for emails, and all my emails land in spam specifically for Gmail.
I want to change the server of the entire web hosting account, is there any free alternative that I can use?
I can use Zoho mail, but that is for each domain zoho offer 5 free email accounts after MX record change, but that is not efficient, I want to change the entire server when I create an account for a domain so that email services are used by default.
need guidance, how I can achieve this, and which service provider is best which can work with CWP itself for all accounts?

thank you.
regards.
hassan.

You will have to get a backup mail exchange -- one that does store & forward.

I don't have any particular recommendations, since it's been more than 12 years since I've needed one. Last one I used was:
