What are spam emails?

When marketers send worthless emails in bulk without personalization in the hopes of getting a few clicks, they’re considered spam emails. Marketers who send spam emails don’t prioritize users. They just want to catch a few fish without putting in the effort to nurture them.

But we know you’re not a spammer and care about your customers. So why do ConvertKit, Google Postmaster, or email tracking tools you use show your spam rate as high? This may happen due to unknowingly exercising spam practices or issues caused by the ESP.

We have revealed the main reasons for your high ConvertKit spam in the upcoming sections. But before that, you’ve to be clear about what spam rate actually means. Let’s uncover that mystery first.

What is spam rate?

Spam rate is the number of people who marked your email as spam out of the total number of people who received that email. Confused? Here is an example.

Suppose you’ve got an email list with 500 subscribers. There is an upcoming holiday, and you decide to send them an email with holiday discounts. After you prepare your email and send it, if 5 people out of those 500 people marked you as spam, your spam rate would be 1% which is an acceptable level.

So coming back to your high ConvertKit spam rate, there might be many reasons why that is happening. Here are the likely reasons.

Reasons for high ConvertKit spam rate

Here’re a few common reasons why your ConvertKit emails may end up in spam.

Not excellent deliverability rates

ConvertKit Email Deliverability

The image above shows you a deliverability test that identifies the percentage of emails that end up in spam, go to inbox, or get lost. As you can see, ConvertKit delivered 81.44% of emails to the inbox. While that number isn’t bad, it can still be significantly better. And if it were high volume commercial emails instead of low volume test emails, that 14.54% of spam emails would’ve bought significant money if they were delivered to the inbox. This may be the hidden reason for the recent hike in your ConvertKit spam rate.

Possessing a poor sender reputation

Similar to how people give you a social reputation based on your past actions, inbox providers also give a reputation to the sender's IP and domain based on their past actions. If a particular IP and domain had a history of spam, surely they’ll get a poor IP reputation and domain reputation. And no inbox provider will accept emails from such sources and direct them to spam. So poor reputation is another major factor in your ConvertKit spam rate.

Not setting up SPF and DKIM

Inbox providers need to know whether an email is coming from a legitimate source, so they use Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) to check its authenticity. So if you don’t set SPF and DKIM, you’re indirectly telling inbox providers, “Hey, I’m not what I claim to be. Please put me in spam.” So if you don’t have SPF and DKIM set up, the hike in your ConvertKit spam rate is self-explanatory.

Interacting with the wrong audience

Suppose you’ve put two hours into a perfect email with nice colors, layout, and content for your awesome shoe products. But if the end-user is not interested in shoes, no matter how cool your email is, it’s all in vain. They’ll not interact with your email and, at worst, mark you as spam. So if you see irrelevant subscribers in your email list, you know why your ConvertKit spam rate is high.

How to reduce the ConvertKit spam rate?

Here are the steps you can take to reduce your ConvertKit spam rate.

1. Improve your sender's reputation

You can start by switching to a dedicated IP address from a shared IP address. Using a shared IP address is no different than living in a robber's house. You may be a good marketer, but spammers who send emails with the same shared IP as you will take its reputation downhill. So move away from a shared IP and switch to a dedicated one on which you have complete control of how its reputation is going to be.

2. Set up SPF and DKIM

You already know the importance of SPF and DKIM from previous sections. So to set up SPF and DKIM, you need to generate their records through online tools such as Easy DMARC. Then you’ve to configure these records in your system and verify them.

3. Interact with the right audience

Your hours of effort will produce more results when you target the right audience. If you sell shoes, target shoe fans. If you sell cricket merchandise, don’t tell football fans to buy them; instead, target cricket fans. It’s all about who you know and who knows you.

4. Use platform activity to send highly relevant content

You may have gathered data about how your users view your product, which pages they checked out, and what features they’re interested in. So don’t let that research go to waste and use it to personalize emails so it’ll anticipate their interests.
