How to verify your own domain on mailchimp?

Question

Domain Name System

Help me figure out the authentication of an email address with your domain name [email protected] The mailbox was created on Yandex and the domain was confirmed there.
The program asks to verify the domain and writes the following:
Warning: Advanced feature
Domain authentication, also known as custom DKIM, is an optional setting. In order to proceed, you will need the ability to customize the DNS records for your domain.
Authenticate your domain with MailChimp to send campaigns that appear to come directly from your domain, instead of from our servers.
After you've made the required DNS changes, please wait 24-48 hours for the changes to propagate.
Changing domain authentication can affect your deliverability. Why?
1. Set a TXT record for areltex.com to:
v=spf1 include:servers.mcsv.net ?all
2. Set the CNAME record for k1._domainkey.areltex.ru to:
dkim.mcsv.net
After making entries:
for TXT in the HOST field: @; in the Type field: TXT; in the entry value field: v=spf1 include:servers.mcsv.net ?all
for CNAME host k1._domainkey entry value dkim.mcsv.net
There have been changes on the mailchimp site
now everything looks like this

I'm trying to verify the mailbox, but nothing comes to it!
Please help I don't know what to do!
