There are several steps to perform a comprehensive domain check:
DNS Configuration: Ensure your DNS settings are correctly configured. This includes setting up SPF, DKIM, and DMARC records. Blacklist Check: Verify that your domain is not listed in any email blacklists. Being blacklisted can severely impact your email deliverability. Email Authentication: Ensure that your domain is authenticated. This can be done through SPF, DKIM, and DMARC records. Domain Reputation: Use tools to check the reputation of your domain. A poor reputation can lead to your emails being marked as spam.
