Problems with sending emails

[backupchiquipoli]

Hi, I am trying to use plugins like GoSMTP and WP Mail SMTP, with both the test sending message says that it went well, however they do not reach the destination.
WP Mail SMTP gave me this message:
Domain Check Results
error icon
spf
Action Needed: It doesn't look like the SPF record required by your SMTP server has been added to your domain. Please contact your SMTP server provider for details on how to find the SPF record, and how to add this record to your domain's DNS.

warning icon
dmarc
Action Recommended: It doesn't look like DMARC has been set up on your domain (chiquipolis.com). We recommend using the DMARC protocol because it helps protect your domain from unauthorized use. Please check out this step-by-step guide for details on how to add the DMARC record to your domain's DNS.

and doing a test with mxtoolbox.com, it answers me: No DMARC Record found

These aren't set up by default. What domain do you need these set up on?
