Posting an update to this community thread as we are releasing some new bot detection software for marketing email. We have had a solution to bots in email for a while now. It was an IP based approach that worked fine but had some flaws. As we have dug into this problem it has become clear that increases in bot activity is an issue felt not just by HubSpot, but the entire email industry.
This week we are rolling out new tools for bot detection to HubSpot customers, and here are some notes on it:
- The new tools take a behavioral-based approach. We look for patterns in the open or click events that indicate a likelihood of being generated from a bot.
- We will be rolling this out to all HubSpot accounts this week.
- No action is needed. If bot filtering is turned on for your account then it will just work.
- This does not change any email campaigns sent in the past. It only impacts emails going forward.
It is impossible to capture all events generated from bots. If you believe you are still seeing bot activity feel free to post comments here or open a ticket with our support team. Our engineering team is continuing to monitor bot activity on our email and will take appropriate additional steps if they are needed.
