Email Monster vs ImprovMX: features, pricing compared
Last reviewed: 25 September 2026
ImprovMX wins if you already own a domain and want a generous free tier of 25 aliases with 500 forwards a day. Email Monster wins if you do not own a domain and want unlimited aliases with a newsletter digest for a lower annual price than ImprovMX's paid tiers.
ImprovMX forwards mail sent to addresses on a domain you already own into your real inbox. Email Monster does the same job but on a ready made subdomain it provides for you, so there is no domain to buy, point DNS at, or maintain.
