How to Protect Your IP Reputation and Avoid Blacklisting

When sending emails to customers, many things can go wrong. Email addresses get entered incorrectly at signup. ISPs can block an IP address even when you have a great reputation. Multiple complaints from recipients can ruin a good reputation in a short amount of time. Unfortunately, these are all very common problems that affect the viability of your program when you focus on quantity instead of quality at the expense of deliverability.

The most common reason ISPs block IP addresses is that they have a poor reputation. ISP spam filters work by checking an email’s header and body for keywords, such as “Fast Cash” or “Credit Cards,” which indicate that the sender is likely to send spam. This can happen even if your company has a good reputation elsewhere – if one of your emails goes out to just the wrong person at the wrong time, it could end up on the blacklist and cause all of your other emails to be blocked as well.

Another reason why ISPs block IPs is because recipients have complained about receiving too many emails from them (or from one particular sender). Spam complaints are often made directly to an ISP when someone receives an unsolicited email or feels like they are being harassed by marketers trying to sell them something; sometimes people will even make false claims against companies just because they don’t like what they do! Whatever the reasons may be behind these complaints, when enough people file one against you then it becomes harder for you to send future messages through their network since those messages would come with an inherent risk of being caught in filters due simply based on who sent them out before (even if you were sending legitimate messages).

That’s why it’s essential to establish your sender reputation when you first start emailing contacts. We call this process IP address warm-up, and it is one of the most important steps in any email marketing plan. Building a good reputation with ISPs takes time and effort, but it is worth the investment.

When you send your first batch of emails, ISPs will see that IP address is sending spam and block it. To prevent this from happening, you need to establish a sender reputation. We call this process IP address warm-up, and it is one of the most important steps in any email marketing plan. Building a good reputation with ISPs takes time and effort, but it is worth the investment.

That said, there are some ways you can speed up the process:

Several factors contribute to your sender reputation, including engagement rates, spam reports and bounce rates. A lot of businesses make mistakes when sending emails to their contact, this may result in poor engagement and delivery issues. For example, sending too many emails at once or sending too many emails in a short period of time (like over a week). These tactics hurt your IP address’s reputation because ISPs see them as reckless behavior for sending emails to subscribers who aren’t engaged with your content or may not be real subscribers at all.

Here are some tips for keeping your reputation clean:

  • Start with a clean IP address. Make sure you have an IP reputation that’s in good standing before you start sending emails.
  • Limit the number of sends you send in a short period of time to new subscribers or those who haven’t engaged with your content. ISPs look at these kinds of behaviors as reckless and may block your IP address from sending emails altogether if they see it happening too often or over an extended period of time.
  • Check feedback from customers regularly so you can improve engagement rates, which will also help increase opt-ins and reduce spam complaints.
  • Keep bounce rates low by ensuring that unsubscribes are removed from lists immediately after they occur (or manually removing them yourself).
