Domains getting blacklisted should be a major cause of concern. EmailGuard monitors well known blacklists to check if your domain is blacklisted.
Some common reasons for your domain being blacklisted include:
Your domain was compromised and used to send unsolicited emails and spam
You forgot to clean your mailing lists and got a high bounce rate
You unknowingly interacted with spam trap email accounts
You did not have proper email authentication for your domain
You may have a shared IP from your webserver or host. This may have been blacklisted in the past, and now that your domain is pointing to it, your domain is also blacklisted
Each blacklist has its own methods of removal. Some remove your domain automatically after some time, while for others, you will need to manually reach out to the blacklist providers and request to be delisted.
You can maximize your chances of staying off blacklists by following the list below.
Use EmailGuard to monitor and protect your domain
Make sure your SPF, DKIM, and DMARC records are valid
Use EmailGuard's DMARC reports feature to ensure your domain is not getting a high number of DMARC failures
Use EmailGuard's contact verification feature to clean all of your uploaded contacts
Monitor your bounce rates for email campaigns and don't email these accounts in the future
If you are doing cold email outreach, or marketing outreach, consider using separate domains for each use case
Use EmailGuard's Hosted Domain Redirects feature to route your domains through a clean private IP address. This is especially important for any secondary domains you may be using
