HeyOtto sorts your mail by priority, writes replies in your style and turns follow-ups into tasks — for Microsoft 365 and Gmail. You review and send; HeyOtto never sends automatically.
It's not about effort — it's email overload. HeyOtto takes over sorting, replying and following up, so you keep your attention on the work that matters.
Hundreds of messages, and the important ones vanish in the noise.
Mails that deserve a reply go cold until it's too late.
Rewriting the same replies every day costs real hours.
Connect your mailbox in under two minutes. From then on HeyOtto works in the background — and you keep full control.
HeyOtto reads every incoming message and files it in a clear category — with a confidence score, so you always see why. Important mail sits on top; noise is quietly filed away.
HeyOtto learns your writing style and signature and prepares a full reply — in four tone variants. You choose, review and send in one click. Never automatically.
Action points in your messages become tasks — linked to the source message. Everything syncs two ways with Microsoft To Do, so nothing slips through the cracks.
Start your day with a concise overview instead of a mountain. What needs a reply, what's a task, what can wait — HeyOtto sums it up for you.
From triage to teamwork. Every feature works from day one — and scales with your business.
Every mail straight into the right category, with a confidence score per decision.
Replies prepared in four tones. You review and send — never automatically.
