Add-on: Spamhaus blocklist checks
Spamhaus runs the blocklists that many mail servers use to decide what to refuse. Spamhaus doesn't allow free commercial use, so these checks are a paid add-on on any plan:
| Per domain | £5 a month |
| Up to 10 domains | £15 a month |
Every plan already checks the free public blocklists.
