Unosend sells prepaid sending credits at $4 per 10,000 emails, through a REST API or SMTP, with no subscription. It gives 3,000 credits once at signup and no recurring free plan, and the site banner says the company is being acquired. - **Value for money: C.** $4 per 10,000 emails, prepaid, with no monthly fee. The vendor does not say what a plan includes beyond sending, so this sits in the ordinary range for email APIs. - **Free plan and trial: C.** 3,000 credits are given once at signup, not each month. The page does not say whether a card is needed. - **Features: C.** REST API, SMTP relay, delivery logs, domains, webhooks and tracking. A dedicated IP is $30 a month, billed annually, and the site's own cards and data disagree on how long credits last. - **Ease of use: C.** No rating on record. It is an API and SMTP relay, so you add domains and wire it into code. - **Platforms and integrations: C.** Web dashboard, API and SMTP. No integrations list, no apps. These are ToolGPA's own grades.

The category's chart of price against score: https://toolgpa.com/charts/email-sending ## Keep it, or make your own? **Keep it.** To replace Unosend 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: 37 of the 50 other email sending services grade higher. - You could not: Mail servers with a good name among inbox providers. - You could not: An API that other software can build on.
