## ToolGPA grades

**GPA: 1.8 out of 4**, graded Nov 13, 2026. Inbound is an email API for receiving, parsing and replying, with sending added, from $9 a month for 5,000 emails. There is no free plan or trial, and the pricing page says nothing about bulk or marketing sends.

- **Value for money: B.** $9 a month for 5,000 emails is at the edge of the cheaper quarter of email tools. Extra domains are $3.50 each and extra capacity $16 per 50,000.
- **Free plan and trial: F.** No free plan and no trial are listed, so every email is paid for from the first one.
- **Features: C.** Email to webhook, address routing, threaded replies, API and CLI, spam filtering and retries. It does that narrow job fully, and does not describe bulk sending.
- **Ease of use: C.** No rating on record. It is an API and CLI product, so setup means DNS, webhooks and code.
- **Platforms and integrations: C.** Web dashboard, API and CLI only. No integrations list is shown.

## Keep it, or make your own?

**Keep it.** To replace Inbound you would be making mail servers with a good name among inbox providers. That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 42 of the 50 other email sending services grade higher. It costs $108 a year.

- You could not: Mail servers with a good name among inbox providers.
- You could not: An AI agent, with the models and the safeguards behind it.
- You could not: An API that other software can build on.
