    You can check if the IP address from which your emails are sent is listed on any blacklists. If you’re using shared servers, like Gmail or Outlook, it’s possible to find your IP blacklisted. This situation is common since these servers are shared by numerous users, some of whom might negatively affect the server’s reputation. However, being on a blacklist doesn’t necessarily impact your email deliverability significantly when using these large shared servers.

    Domain Blacklists

    You can also verify whether your domain has been marked on any blacklists. It’s not uncommon for domains, especially new ones or those on shared servers like Gmail or Outlook, to appear on blacklists temporarily. If you see your domain listed, there’s often no immediate cause for concern, as this may not significantly impact your overall email deliverability.
