Choose Immune when

Public and shared inboxes are the pain

  • Cheap per-seat filtering still leaves support@ full of human-looking junk.
  • You want a customer-facing challenge experience, not only a quarantine digest.
  • Virtual addresses should route straight into the tools your team uses.

SpamTitan may still fit when

You need something else

  • An MSP needs one inexpensive filter across hundreds of mailboxes.
  • The main goal is malware and bulk spam at the lowest seat price.
