Straight Answers
How do you know who sold my data?+
Each alias is bound to exactly one company. If a message ever arrives from any other sender, that sender is by definition using an address only that one company ever had. We log it and name them.
Can I reply to emails from an alias?+
During the beta, whosold.me is receive-only: mail forwards to your real inbox and you reply from there. Reply-masking is on the roadmap.
Does this impact delivery speed?+
No. We relay over standard SMTP in milliseconds. Mail lands in your inbox as fast as any forward, ARC-sealed so it passes authentication.
What do you store?+
The sender, the subject, and the time. Never the message body, never attachments. Nothing to sell, nothing to breach.
