ImprovMX forwards mail sent to your own domain to an inbox you already have, free for 1 domain and 25 aliases. It isn't a mailbox and the free plan has no sending or rules. Sending starts at Light for $50 a year. - **Value for money: B.** Free for 1 domain, 25 aliases and 500 forwarded emails a day, and Light is $50 a year, about $4.17 a month. Sending isn't in the free plan. - **Free plan and trial: B.** 1 domain, 25 aliases, 500 forwards a day, 7-day logs and API access for nothing. One person could live on it, as long as they don't need to send. - **Features: C.** Alias forwarding, sending from your domain, routing rules, logs and webhooks, and an API. It does forwarding fully, but that's a smaller job than a mailbox, and sending needs Light. - **Ease of use: C.** No store rating on record. You change your domain's DNS records to point mail at it. - **Platforms and integrations: C.** Web only, with an API and webhooks. No integrations list, phone app or desktop app. These are ToolGPA's own grades. Graded from this listing, whose facts were read from ImprovMX's own pages on 12 November 2026.

That is not a weekend's work, with an AI app builder or without one. It costs $50 a year. - You could not: Mail servers with a good name among inbox providers. - You could not: Filters that read every message as it arrives. - You could not: An API that other software can build on.
