Gmelius vs Mailtwine

Gmelius is a Gmail-native platform for creating AI agents that carry out defined team jobs across connected tools. Users describe an agent’s task in plain language, choose the inbox it monitors, connect tools, and decide which actions need approval, without writing code. Meli, described as an AI Chief of Staff, supplies agents with context about a team’s clients, history, and priorities. Gmelius also provides shared Gmail inboxes and labels, shared drafts, email notes and mentions, delegation, templates, analytics, calendar tools, and scheduled sending. Listed integrations include Google Groups, Google Workspace Admin, Meet, Calendar, Salesforce, HubSpot, Slack, Trello, Nicereply, Zapier, Make, and Relay.app. The Gmail extension supports Chrome, Microsoft Edge, Brave, and Opera; listed platforms also include Android, iOS, API, and web. There is no free plan, but a seven-day trial gives access to Growth; afterward, users must choose a paid plan or the account is suspended. Prices start at $19/user/mo (annual).

Mailtwine is an email service for Android, iOS, Linux, macOS, web, and Windows. Its inbox triage tools help sort messages, and AI can draft replies. Thread summaries condense email conversations, while automatic sending and follow-up actions cover additional parts of email handling. The listed regular pricing model is paid, and there is no free plan. A beta offer called “Unlimited for FREE Beta access” costs nothing, billed at $0 during beta. It includes all features without plan limits during beta, and beta users are eligible for early-bird pricing. That beta offer is distinct from the paid product: the paid-plan price will be announced before launch. The listed platforms span mobile operating systems, desktop operating systems, and web access. For readers comparing email tools, the key distinction is between the no-cost, unrestricted beta access and the later paid service, whose price is not yet specified.
