Verification code delivery issues
Incident Report for Fluid Attacks


An unknown number of users experienced issues accessing the platform as they were not receiving the verification code in their emails. The issue was reactively discovered by a customer who reported the problem to one of our engagement managers [1] indicating that they could not access the platform. The problem was resolved in 1.1 days (TTF) [2].


We use SendGrid to send emails to our users. Each email includes a link for globally unsubscribing from all SendGrid emails. Some email providers have automated programs that click on all links in emails, leading to unintended global unsubscribes for our users.


A new functionality was implemented requiring users to confirm their intention to unsubscribe. Users are now redirected to an endpoint where they must explicitly confirm their desire to unsubscribe from our emails [3].


To address this, a new functionality was created requiring users to confirm their intention to unsubscribe, preventing accidental opt-outs. THIRD_PARTY_ERROR
