If your IP address is blacklisted, any emails you send will bounce back until you’re removed from the blacklist. That means you won’t be able to contact anyone by email until you’re able to resolve the issue.
If you’re just an individual, being blacklisted could be very inconvenient. It’ll mean you can’t answer any emails, or contact anyone using your email account. This can be very annoying if you need to reply about an interview or if you’re trying to send back a recent purchase.
If your company’s account has been blocked and you rely on marketing emails to grow your customer base, this can be very damaging. This can lead to a reduction in business until you can get the issue fixed.
If you’ve sent emails to a number of different addresses and they’ve bounced or been rejected, then it’s worth checking if your IP address has been blacklisted. If it has, you’ll want to resolve the issue as soon as you can.
