Your spam complaint rate shows how often subscribers mark your emails as spam.
People usually report emails as spam for these reasons:
It is important to know when and why you get spam complaints because too many can damage your email sender reputation.
Unlike bounce rate, open rate, or click rate, which vary by industry, your spam complaint rate should always stay low.
No matter the industry, keep your spam complaint rate below 0.1%, that is more than 1 complaint per 1,000 emails.
Email marketing metrics help you understand how well your content connects with your audience. Spam complaint rates, for example, show whether you are following the right (legally required) practices by sending emails only to those who subscribed.
Email providers take spam seriously, and even a small complaint rate typically above 0.1% can be a red flag. However, different providers have their own limits for what they consider too much spam.
If you use email services like Mailchimp, ActiveCampaign, or Campaign Monitor, they will notify you if your campaign receives too many spam complaints.
A high spam compliant rate can make people question how you collect email contacts, whether you provide an easy way to unsubscribe, and if you regularly clean your email list. It damages your sender reputation and groups you with spammers that internet providers try to block.
If you get too many spam complaints, email providers may start marking your emails as spam automatically. Even if your content is good, your emails might go straight to the spam folder or get blocked, leading to more bounces.
When emails do not reach inboxes, fewer people open and click them, hurting your marketing results. If spam complaints continue, services like campaign monitor could even suspend your account.
If your emails are not getting delivered, check your spam rate to fix the problem.

Reduce spam complaints with email validation
If your spam is too high, here are some simple ways to lower it after using our spam rate calculator.
Use FareOf email validation
The quickest way to reduce spam complaints is by regularly cleaning your email list. FareOf email validation helps remove invalid emails that bounce and detects users who frequently mark emails as spam.
Some people have a history of reporting emails as spam, even when they signed up. FareOf identifies these “abuse emails” so you can remove them before sending your campaign. This helps prevent spam complaints before they happen and improves your email deliverability.
Keep your email bounce rate low
Email validation also helps lower complaints by reducing your bounce rate to 2% or less. Fewer bounces mean better email deliverability and a stronger sender reputation, reducing the chances of your emails landing in spam.
When emails reach the inbox, they look more legitimate and trustworthy. This makes people less likely to mark them as spam. And if someone is not interested, they can simply unsubscribe instead of reporting your email.
Include an unsubscribe link in your emails
Always add an unsubscribe link to your emails. It is so important that most email platforms won’t let you send a campaign without one.
The CAN-SPAM Act requires you to email only those who have given clear permission and to provide a simple way for them to opt out anytime.
Unsubscribe links are a must
Always include an unsubscribe link in your emails. Most email providers require it. If you do not, people may mark your emails as spam or even report your business to the FTC.
Even with a clean email list and great content, some people may still mark your emails as spam.
This often happens when someone signs up for a freebie or one-time offer and forgets they subscribed. Instead of unsubscribing, they report your emails as spam.
To prevent this, use a double opt-in for all email sign-ups. After entering their name and email, they should receive a confirmation email that explains:
This extra step helps filter out people who are not really interested, keeping your spam complaint rate low.
Your email provider may track spam complaints, but FareOf helps you stop them.
With email validation, you can quickly detect invalid emails, frequent spam reporters, catch-all emails, toxic domains, and spam traps. Regularly cleaning your email list is affordable and helps lower your bounce rate while improving email deliverability.
A spam complaint happens when someone marks an email as spam in their inbox, spam folder or promotions tab. This tells email providers that the user did not willingly sign up, and the sender might be breaking CAN-SPAM Act rules.
The spam complaint rate is the percentage of emails that recipients mark as spam. You can check this rate in your email campaign reports after sending a campaign.
The ideal spam complaint rate is 0.1%, meaning 1 complaint per 1,000 emails. While this is the safest limit, some email providers may allow up to 0.5%.
You can decrease your spam complaint rate by:
You can find your spam complaint rate in your email service provider’s campaign reports, usually alongside open, click, and bounce rates. Some providers call “abuse reports.”
Our spam rate calculator checks if your rate is safe, risky, or too high. Based on our metrics, it also estimates how many spam complaints you can reduce with FareOf email validation.
