Let’s jump right in and make your first email spam tests with our top tools.

What is an email spam checker tool?

An email spam checker is a handy software that scans your emails to identify any content or elements that might trigger spam filters

This tool helps you make sure that your emails reach your recipients’ inboxes rather than getting lost in the spam folder. It’s like having a virtual assistant that double-checks your emails to improve deliverability and engagement.

Why should you check your emails for spam?

Checking your outgoing emails for spam is incredibly beneficial for a number of reasons.

The most important are:

You avoid deliverability issues

When you check your emails for spam, it helps you prevent deliverability issues. For instance, if you send a newsletter to your subscribers without spam checking, it might get flagged as spam due to certain keywords, and your subscribers may never see it in their inboxes.

Maintain sender reputation

Sender reputation is absolutely crucial for email marketing. Provided that you regularly spam-check your emails, you can maintain a positive sender reputation. For example, if you consistently send emails with spammy content, email service providers might blacklist your domain. Fixing this issue is a painstakingly long and difficult job.

Improve open rates

Do you know how you can have a higher chance of landing in the recipients’ primary inbox? It’s possible exactly by avoiding triggering spam filters. This can significantly improve your open rates

Imagine sending a product discount offer that goes unnoticed because it ended up in the spam folder – a spam check could have easily prevented that.
