Shroud Email cons:

- service saves emails marked as spam. If email address gets spam, then alias can be deleted by the user. Alias deletion prevents spam. Competitors do not store any emails, because it is better for privacy.

- If you respond to reverse alias then the recipient knows you use Shroud.email (text: via Shroud.email). Less private solution.

- the service adds additional its own text to email content like "Shroud.email didn't find any trackers."

- How user data are encrypted?
