Email Marketing Tool Tips: The Most Popular Spam Filter Testing Tools0
Getting caught in the spam folder is an email marketer’s nightmare, but it’s more common than you might think. If you’re not watching and paying attention, it’s easy to get your emails blocked or blacklisted and not know it. Or there might be issues with your infrastructure or the content of your email that can trigger spam filters, preventing your messages from being delivered to the inbox.
But how do you know if your email is at risk of being sent to the spam folder? Spam filter testing tools are instrumental in getting this critical visibility.
We asked thousands of marketers if they run their emails through spam filter tests before sending—and which tools they use to do so. Here’s what we found.
The majority of brands use spam filter testing tools
53.8% of all marketers say they rely on spam filter testing tools to test their emails for potential spam issues before they send, according to our State of Email research. Third-party spam testing tools are the most popular, with 37.7% of brands using them. Another 16.1% of brands rely on the spam testing tools provided by their email service providers (ESPs) for pre-send spam testing.
Marketers who use spam filter testing tools have better visibility into blacklistings
Marketers who use third-party spam filter testing tools are 50% more likely to report being blacklisted (22% vs. 15%) than those who don’t.
But that doesn’t mean that those brands get blacklisted more often. It’s safe to assume that most of these differences are due to tool users having much better visibility into their deliverability. After all, you can’t report or resolve a blacklisting if you aren’t aware of it.
Here’s another stat that supports that theory: Brands who use spam filter tests before sending emails reported an ROI of 51:1, while those who don’t report an ROI of 39:1. Having better visibility into blocks and blacklistings means you can take action more quickly—and that leads to better email program performance.
