|---|---|---|
| Hosting | France (dedicated infrastructure) | Cloud (UK servers) |
| Custom domain | ✅ All plans (from free) | ✅ Paid plans only |
| Built-in mailbox | ✅ Yes (read, reply, compose) | ❌ No (forwarding only) |
| Free plan | 1 domain, 10 aliases, 100 emails/mo | Unlimited aliases (shared domain), 10 MB/mo |
| Paid entry price | €9/mo (Pro) | $1/mo (Lite), $3/mo (Pro) |

AnonAddy is especially generous on its free plan: unlimited aliases on its shared domain (@anonaddy.com or @addy.io), ideal for personal use without your own domain. The main limit is bandwidth (10 MB/month of received email).
SMTPy bets on your own domain from the start: 1 custom domain, 10 aliases, 100 emails/month. If you already have a domain and want a professional email identity, SMTPy clearly wins.
AnonAddy is built for pure forwarding: emails are relayed to your primary inbox, with no storage or reading interface. You manage aliases from a dashboard, but you do not read your email inside addy.io.
SMTPy includes a full web mailbox (shared inbox): you can read, search, reply, forward, and archive email directly in the interface — a significant advantage for centralizing your communications.
addy.io is a UK service, also self-hostable (a Laravel install) if you want to run your own server. SMTPy takes the opposite bet: a managed service hosted in France, with no server to administer — your data stays in the EU and your addresses stay on your own domain.
AnonAddy is cheaper ($1/month for custom domains). SMTPy costs more but offers more: a built-in mailbox, advanced analytics, webhooks, multi-user teams, and a full API.
