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. So if 200 people received your email and two of them mark you spam, your spam rate is 1%. You've to maintain the spam rate below 1% which is the industry standard.

But as you check your email tracking tool, you may notice your spam rate to be more than 1% or moving in an upward trend. But why?

So let's discuss a few major reasons for your high Sendinblue spam rate and how to fix them.

Reasons for high Sendinblue spam rate

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

• Poor deliverability rates

Email Deliverability Report has done a recent test to find out the deliverability rates of different ESPs. In this report, it was found that Sendinblue had successfully delivered 79.71% of emails to the inbox, 16.24% of emails to the spam folder, and the remaining 4.05% of emails got lost.

These aren’t the ideal stats a serious email marketer would desire from their ESP as that 16.24% of emails could bring significant business if they ended up in users’ inboxes.

• Using blacklisted IPs

Inbox providers use third-party blacklist databases to find spammers. Even if you're not a spammer but use a spammer's blacklisted IP, you'll not get any good treatment from inbox providers. And in the free plan of Sendinblue, your emails will be sent from a shared IP that may be hijacked by a spammer.

• Not warming up new IPs

Inbox providers don't really like new IPs since spammers often set up new IPs just to send junk emails. So if you start sending high-volume emails without warming up your IP address, there is a high chance that email will land in the junk folder. So you're unknowingly acting like a spammer and seeing your Sendinblue spam rate spike.

• Using spam trigger words

Apart from sending bulk emails, spammers also use certain types of content and words in their emails to deceive people. So if you unknowingly use similar types of content these spammers use, guess what will happen? Your emails will end up in spam. So this may be the hidden reason why your Sendinblue spam rate is high.

How to reduce the Sendinblue spam rate

Here are the steps you can take to reduce your Sendinblue spam rate:

1. Switch to a dedicated IP address

A dedicated IP address lets you have complete control over its reputation and other spammers won’t hurt your IP since you’re the only owner. But the requirement is that you must follow good email etiquette and practices, otherwise, inbox providers will also blacklist your dedicated IP address.

2. Warm up your domain

Warming up is the practice of making your new domain familiar with inbox providers so they won’t send your emails to spam when you start high-volume emailing. You do this by sending emails to a small number of users who will open your emails. Then after some time and initial engagement, you can eventually start sending your high-volume marketing campaigns.

3. Be aware of spam-like content

“Lottery” “Jackpot” and “$$$” are some of the words and symbols spammers commonly use in their emails. So if you unknowingly use such words in your subject line and email body, you’ll likely end up in spam. Besides that, try adding links instead of attachments since inbox providers can consider attachments as potential viruses.
