I will setup email, spf, dkim, dmarc and bimi records

Your sending email domain is correctly set up for better email delivery and avoid going to spam. You have to use the email authentication method.

SPF is very important, and it MUST be fixed. It is an email authentication method that helps to verify the message is being sent from an authorized server. Setting up SPF helps to prevent spoofing, spam, and improve message deliverability.

DKIM it adds a signature that gets verified by the receiving server to ensure the messages are not forged or changed during transit.

DMARC it tells the receiving server to checks SPF and DKIM to verify the emails are coming from the authorized servers.

BIMI (Brand indication message identification) is a new standard to show your logo on every email so recipients can recognize and trust your brand.

Your email is essential for your business communication. Don't let it land to spam or someone spoof that.

Also, I can check and fix other DNS related problems;

MX record - mail server like Gsuite, Outlook, Office, Zoho

NS record - name server like Squarespace, Wix, Webflow, Siteground

CNAME or TXT record for Lemlist, Sendgrid, Mailgun, Klaviyo

Thanks
