5 Top Reasons Your Emails Get Blocked

5 Top Reasons Your Emails Get Blocked

There are a number of reasons your emails may get blocked entirely (or sent to the spam folder). Here are 5 top reasons your emails get blocked:

1. Reputation

Your email reputation consists of both your IP address reputation AND your sending domain. More and more providers are relying more heavily on the sending domain. Gmail is one that we're seeing domain reputation playing even more of a role than IP reputation. What this means is that simply the presence of a bad domain in your emails may cause the message(s) to go to the spam folder... What's worse, the notification that Gmail provides won't even tell you that's the problem!

2. Content

We've talked about message content time and time again and this is one of the biggest factors that determines what happens to your email messages. It's important to test your content BEFORE sending AND to make sure the content you're sending to your list is what they want!

3. Frequency

Sending TOO MUCH mail can cause your emails to get blocked at the network level OR submitted to a blacklist. One of the first things people do when they see a decline in sales is send more often to try to make up for it rather than look at underlying problems like message to market match, engagement, list building, etc.

4. Volume

Sending too much mail at once can get your email blocked. This is why we provide a specific warm up schedule and recommendations with regard to number of IPs for volume. We also recommend using common sense when adding more subscribers to your list. If you are mailing to 20,000 people and then all of a sudden, you send out to 100,000, it may appear to the network providers that someone is launching an attack on their mail server or sending out spam. Use common sense when adding to your list and once you have completed your warmup, your list growth should be organic and grow over time. If not, this is an indicator that you are not following proper list building practices and are asking for deliverability problems.

5. List Quality

You need to be constantly cleaning your list. Old lists and purchases lists are likely to get your emails blocked or blacklisted entirely. There will likely be bad addresses, bad domains, spam traps, and the like. Many of these people have not signed up of your email and/or don't want it. This can block the connection before it ever even leaves your server! List hygiene and proper list building practices are essential.
