Overall verdict
Why this product is good
Recommended for
Nylas Mail was particularly well-suited for users who manage multiple email accounts and need enhanced functionality beyond basic email management, such as advanced search, email scheduling, and analytics. Since it's no longer available, users with similar needs should look for other modern email clients that offer these capabilities.

As answered by people managing Nylas Mail and Coachstack.
Coachstack's answer:
Next.js and React with TypeScript, Supabase (PostgreSQL with row-level security), Tailwind CSS, hosted on Vercel.
Coachstack's answer:
Coachstack is built around the decision a coach makes before each session. One page shows how the last session went: sets done, pain reported, messages waiting, and the session planned for today next to what the client lifted last time. Load increases are calculated from the logged sets and arrive as proposals with their reasons; nothing changes the programme until the coach approves. If a client reports pain on an exercise, no increase is proposed on it until the coach has read the report.
Coachstack's answer:
Because it keeps the training record and the coaching decision in one place. Clients log every set from the phone's browser, with nothing to install, and the logger keeps working without signal. The coach can log on the same session from their own phone or tablet. Programmes and clients come in from Excel or CSV, so there is no starting from zero. It is free during the beta, in English and Italian.
Coachstack's answer:
Personal trainers who coach both in person and online: independent coaches and small studios run by one coach, with clients who train in the gym with them and on their own between sessions.
Coachstack's answer:
Many personal trainers still run their business on spreadsheets, paper notes and chat messages: the programme lives in one file, the client's sets in another, and the reason a load was changed lives nowhere. Coachstack was built in Italy to put those pieces together, so that every session is recorded once and the next one starts from what happened in the last.
