In this guide, we’ll break down 5 working ways to fix emails going to spam and make sure your message actually gets seen.
Are your important emails ending up in your customers’ spam folders instead of their inboxes? You’re not alone.
Email filters have become stricter than ever. Even legit emails are often flagged wrongly.
You just need the right fixes, and we’re giving you five of the fastest that work in 2025.
Let’s go in.
Why Emails Go to Spam in 2025
Before we fix it, let’s quickly understand why it’s happening.
Here are the top reasons your emails end up in spam:
- You’re using too many salesy or trigger words (like “Buy now”, “Free gift”, “Act fast”)
- Your sender reputation is low
- You don’t have proper authentication settings like SPF, DKIM, or DMARC
- People don’t open or click your emails (low engagement)
- You’re sending to bad or old email lists
Now let’s go into how to fix emails going to spam fast.
1. Authenticate Your Email Domain (SPF, DKIM, DMARC)
This is the number one thing email filters check.
What to do:
- Set up SPF (Sender Policy Framework)
- Enable DKIM (DomainKeys Identified Mail)
- Use DMARC (Domain-based Message Authentication)
Most email platforms (like Gmail, Zoho, Mailchimp, etc.) have guides for this.
Why it works:
Email providers like Gmail want to know your email is really from you. These records prove that you’re not a scammer.
Without them, even your best email can go straight to spam.
This is a must-do if you want to fix emails going to spam permanently.
2. Clean Your Email List Regularly
Old, inactive, or fake emails hurt your sender reputation.
What to do:
- Use email verification tools like ZeroBounce, NeverBounce, or MailerCheck
- Remove emails that bounce
- Delete subscribers who haven’t opened in 3+ months
Why it works:
When you send emails to people who never open them, it tells email providers your content is unwanted. Cleaning your list boosts your open rate, which helps prevent emails going to spam.
3. Avoid Spammy Words and Formatting
Certain words and formatting scream “spam” to inbox filters.
Watch out for:
- Too many CAPS or exclamation marks!!!
- Words like “FREE”, “LIMITED TIME”, “WIN BIG” in the subject
- Red fonts or yellow background
- Using URL shorteners like bit.ly
What to do instead:
- Write like a human, not a robot
- Be clear and personal
- Use natural formatting and normal punctuation
This simple change can fix emails going to spam more than you think.

4. Ask Subscribers to Whitelist You
This is a very easy and underrated method.
What to do:
- Ask new subscribers to add your email to their contacts
- Give simple instructions on how to do it (especially for Gmail)
Why it works:
When someone whitelists your email, it tells the email provider “this is a safe sender.” It becomes almost impossible for your emails to go to spam again.
This small action can fix emails going to spam for good with your subscribers.
5. Warm Up Your Domain and Maintain Good Sending Habits
If you just bought a new domain or you haven’t sent emails in a while, don’t blast 1,000 emails on day one.
What to do:
- Start small (20–50 emails/day) and increase slowly
- Use tools like Instantly, Mailwarm, or Lemwarm to warm up
- Always send value, not just sales content
Why it works:
Warming up builds trust with inbox providers. It shows you’re not a spammer. Good sending habits mean high open and click rates, which keeps your emails out of spam.
So if you want to fix emails going to spam, build your reputation slowly and steadily.
Bonus: Use a Spam Score Checker
Before sending your next email, test it with a tool like Mail Tester or GlockApps.
These tools tell you:
- If your email is likely to go to spam
- What issues you need to fix
- A score you can work to improve
It’s like proofreading your email before hitting send. And it’s one of the easiest ways to fix emails going to spam.
