How Does an Email Spam Filter Work?
All the email providers, like Gmail or Yahoo, have a strict spam policy. Millions of people are using spam emails as a tactic to sell their products, like sex drive pills, fake-brand appliances, or many other things.
To tackle this issue, the email provider uses an algorithm that can detect malicious links, nude images, or any suspicious doorways and send them directly to the spam folder of the email owner.
This is a good thing, and it helps people like us to stay away from this fake and unethical stuff. However, this becomes a headache as well when your dozens of hours of effort go into this folder.
A spam-detection algorithm is a computer system that can make mistakes. So sometimes it sends the emails that are not spam into the spam folder. It happens due to mistakes of the sender.
How to Improve MailerLite Email Deliverability?

I also had to combat this issue when I started email marketing back in 2015. However, soon I found ways to avoid this issue. So here are the steps that I personally take whenever I get into this trouble. And believe me, the results become positive soon after using these steps.
1) Use Your Own Domain to Send Newsletters:
Many people make a mistake to sending emails from email providers like Gmail, Yahoo Mail, and other similar platforms. You need to understand that these email platforms can be detected as spam, so avoid them.
You should always use a domain email like marketing@zupanta.com to send commercial or marketing emails. MailerLite allows you to set up an email domain and send emails in bulk.
2) Pick a Correct ESP:
Your email service provider is very depended in your deliverability ratio. If you use a weak or outdated ESP, your emails may act like shy students in a classroom. They hide in the corner and never talk to anyone.
MailerLite gives you a strong base. It sends your emails through trusted servers and keeps your sender score in good shape. It also follows global email rules, so inbox providers trust your messages more.
If you want good deliverability, do not switch between random ESPs every few months. Stick with one reliable platform. Build a clean sender history. A stable sending reputation helps your emails land in the inbox more often.
3) Warm Up Your Email Domain:
Never start sending bulk emails on day one. Slow and steady wins here too. Start with a small number of emails. Increase your sending volume every few days. This lets inbox providers see you as a real person and not a spam bot with rocket-speed hands.
MailerLite also offers warm-up guidance. Follow it. It helps your domain create a good reputation with Gmail, Yahoo, and Outlook.
4) Clean Your Email List:
A dirty email list is like rotten fruit in your fridge. It affects everything. Remove inactive users, fake emails. Remove people who never open your messages.
MailerLite has a built-in list cleaner. Use it. A clean list reduces bounce rates. Low bounces tell email providers that you are a safe sender.
5) Avoid Spammy Words and Triggers:
Inbox providers hate aggressive sales words. They treat them like red flags. Avoid phrases like “Free!!!”, “100% Guarantee,” or “You Won a Prize.” These lines attract spam filters faster than cookies attract kids.
Keep your subject lines simple and honest. This builds trust with your subscribers and with email filters.
6) Add a Clear Unsubscribe Option:
Do not hide your unsubscribe button. If people cannot find it, they may report your email as spam. That hurts your deliverability badly. A clear unsubscribe link keeps your list safe and clean.
MailerLite already gives you simple unsubscribe tools. Use them in every email.
7) Use Double Opt-In:
People who confirm their subscription are more engaged. They open more emails. They click more links. Email providers love this behavior. It shows that your audience wants to hear from you.
MailerLite lets you enable double opt-in with one click. It is a small step with a big impact.
8) Send Emails Consistently:
Do not disappear for months and then return with a blast of messages. Your audience will forget you. Email filters will find this behavior strange too.
