Summary
What email marketers say8Marketer opinions
Email marketer from Reddit responds that corporate security software often clicks links in emails to check for malicious content. This can cause a large spike in clicks, particularly from internal IP ranges. Check IP addresses, user agents and timing of the clicks
Email marketer from StackExchange explains that a sudden increase in bot clicks could be due to new email security measures implemented by recipient email providers. These systems automatically click links to check for malicious sites, resulting in inflated click-through rates. Check the user agent of the requests.
Email marketer from Email Geeks asks whether the clicks are unique or total, and if recipients are clicking all available links once or multiple times.
Email marketer from MarketingProfs explains that email pre-fetching by mailbox providers and security software could be the reason for a spike in clicks. They share that filtering by IP can help in some situations but it is not always reliable
Email marketer from Neil Patel's Blog explains that identifying bot traffic involves analyzing IP addresses, user agents, and behavioral patterns like unusually high click-through rates or clicks occurring at odd hours. He suggests using tools like Google Analytics to segment and filter out bot traffic.
Email marketer from Litmus responds that Apple's Mail Privacy Protection (MPP) can inflate click rates as it pre-loads email content. This can register as a click even if the recipient doesn't actually engage with the links. They recommend segmenting Apple Mail users and analyzing their engagement separately.
Email marketer from SparkPost responds that a surge in clicks might be due to mailbox providers improving their pre-fetch link checking capabilities. They suggest monitoring engagement metrics and adjusting sending practices accordingly, but don't worry too much about it because it isn't real.
Email marketer from EmailOversight.com shares that a sudden surge in click activity might stem from new security software being implemented by receiving mail servers, automated security scans that pre-fetch links to detect threats, or even competitors attempting to skew your engagement metrics.
