Summary
What email marketers say9Marketer opinions
Email marketer from Medium suggests implementing user agent filtering to identify and block bot traffic. Analyze the user agents associated with clicks and opens. If you find user agents that are commonly associated with bots or automated systems, you can filter them out to improve the accuracy of your email marketing metrics.
Email marketer from MarketingProfs recommends implementing rate limiting on your website to prevent bots from overwhelming your servers with click requests. Rate limiting can help identify and block bots that click links at a high frequency. This also ensures that legitimate users have a better experience on your site.
Email marketer from StackOverflow recommends setting up a bot trap by including a hidden link in your email. If a user clicks the hidden link, it's likely a bot. You can then automatically unsubscribe or flag these users to prevent them from skewing your metrics. Regularly monitor your analytics to spot unusual patterns.
Email marketer from HubSpot shares that analyzing the time-to-click metric can help identify bot activity. Bots tend to click links immediately after receiving an email. By monitoring and filtering out clicks that occur within a few seconds of email delivery, you can reduce the impact of bot traffic on your email marketing metrics.
Email marketer from Litmus explains that identifying bot clicks often requires analyzing patterns. Look for clicks that happen immediately after email delivery, multiple clicks from the same IP address within a short period, or clicks originating from known data center IP ranges. Also, engagement metrics like unusually high click-to-open rates can be indicators of bot activity.
Email marketer from Mailgun shares that adding unique tracking parameters to your links helps in identifying the source of clicks. By analyzing these parameters, you can filter out clicks originating from bots based on user agent, IP address, and time of click. Implementing reCAPTCHA on landing pages can also prevent bots from artificially inflating click rates.
Email marketer from Reddit recommends implementing honeypot links in emails. These are links invisible to humans but easily crawled by bots. Clicks on these links indicate bot activity, allowing you to filter out those engagements from your legitimate metrics. Also, consider excluding known bot IP ranges from your analytics.
Email marketer from Email on Acid recommends monitoring IP addresses that interact with your emails. If you see a high volume of clicks or opens from a single IP address, it could indicate bot activity. You can then block these IP addresses from future campaigns to improve the accuracy of your metrics.
Email marketer from Quora recommends using reCAPTCHA on landing pages to differentiate between human users and bots. This prevents bots from artificially inflating click rates and ensures that only genuine clicks are recorded in your analytics. This is a simple but effective way to reduce bot traffic.
What the experts say8Expert opinions
Expert from Spamresource.com shares that monitoring the reputation of IP addresses clicking your links can help filter out bot traffic. If you identify clicks originating from IP addresses with a poor reputation, it's likely bot activity. Use IP reputation databases to identify and block these IP addresses from future campaigns.
Expert from Wordtothewise.com explains that reviewing engagement metrics, such as the time between email delivery and click, can help identify bots. Bots typically click links immediately upon receipt of an email. Monitoring these metrics and setting up alerts for unusually fast clicks can aid in identifying and filtering out bot-generated traffic.
Expert from Spamresource.com explains that analyzing user behavior patterns can help in identifying bot clicks. Look for inconsistencies in how users interact with your emails, such as unusually fast click times or high click rates from specific IP addresses. Segment your audience based on engagement behavior to better identify and isolate bot-like activity.
Expert from Email Geeks explains that NHI opens are nearly impossible to detect accurately due to caching and privacy measures. However, NHI clicks can be identified because they are not cached and are used for spam/malware filtering. Devices doing NHI clicks try to look like humans to bypass defenses but don't aim to deceive senders about human interaction.
Expert from Email Geeks shares that you can do a crude cleanup of stats by looking at timestamps, as NHI clicks are often at delivery time. If serving content, analyze user agent behavior on the landing page for bot-like activity.
Expert from Email Geeks explains that it is up to Sendgrid and their customers to decide if they want to start proactively removing bot clicks, but that it would make sense for them to do so.
Expert from Email Geeks shares that there's no need to retroactively tidy up click data because it's relatively easy to adjust the counts as they're received.
Expert from Email Geeks states that Sendgrid engineers are not talking to Microsoft about this issue, as everyone is aware of what is happening. He adds that NHI has been a problem for years if you're trying to use clicks as a metric and also that it's not just a microsoft issue.
What the documentation says5Technical articles
Documentation from IETF explains that regularly updating user agent lists is essential for identifying bot traffic. By comparing user agents accessing your links with known bot user agents, you can filter out a significant portion of bot-generated clicks and opens. This approach requires maintaining an updated database of bot user agents.
Documentation from Google Analytics explains that using custom segments, you can filter out bot traffic. Set up segments based on known bot IP addresses or user agent patterns. This helps you analyze your website traffic without the skewing effects of bot activity, allowing for more accurate insights.
Documentation from SparkPost explains that monitoring engagement metrics, such as time between email sent and first click, can help identify bots. Bots often click links immediately after the email is received. Setting up alerts for unusually fast click times can help you detect and filter out bot activity.
Documentation from Microsoft Docs explains that the SmartScreen filter in Outlook scans emails for suspicious activity, including links that might lead to phishing sites or malware. While it doesn't directly identify bots, it can block or flag emails with links frequently clicked by bots, reducing the impact of malicious bot activity.
Documentation from Cloudflare explains that using a bot management tool helps in identifying and blocking malicious bots. Cloudflare’s bot management service analyzes traffic patterns, user behavior, and other factors to differentiate between human users and bots. This ensures more accurate email marketing metrics.
