Inbox whodunit: Algo or alibi?
Someone at BrowserStack Is Leaking Users' Email Address
No spam promise in flames as Apollo points at BrowserStack
TLDR: A BrowserStack-only email surfaced in Apollo’s system; Apollo said it came via BrowserStack’s data-sharing network, sparking outrage. Commenters are split between “hack” and “shady sharing,” joking about the “proprietary algorithm” and guessing the teased “very big company” is Amazon—either way, trust just took a hit.
One user set a trap: a unique email used only for BrowserStack. Days later, that address got cold-emailed. The sender said they pulled it from Apollo.io. Apollo first waved a “proprietary algorithm” wand, claiming they guessed the address from public info. The crowd cackled: “How much AI does it take to guess firstname.lastname?” When pressed, Apollo allegedly changed tune and said the email came from BrowserStack via its “customer contributor network.” Cue the popcorn.
Commenters split into two feisty camps. The “It’s a hack, folks” crew insists the simplest answer is a compromise: “their db/email list has been compromised,” says one, echoed by others who point to recent leaks and warn that breaches are common. Another faction calls it shady data sharing dressed up with corporate buzzwords, roasting the “No spam, we promise” tagline as meme fuel and calling the situation “beyond outrageous.” One user drops a spicy theory linking this to other browser companies and even wonders if a shared “headless browser” flaw is at play—pure speculation, but it stoked the thread.
Meanwhile, everyone’s guessing the “very big company” teased for the phone-number leak—one bold pick: Amazon. The mood: suspicious, outraged, and very online, with folks side-eyeing vendor “contributor networks” and demanding receipts while waiting for BrowserStack to say anything at all.
