What is the best way to send the same kind of email again and again with AI?
The short version: Write it from notes each time and let the tool fill in the specifics. Opsis writes your next line wherever you type: Slack, Gmail, Outlook, Teams, Notion, Google Docs and AI chats like Claude and ChatGPT. Press Tab to keep it. It can also draft a whole reply from a few notes, using facts from your own work: what's on your screen, the apps you connect (Gmail, Calendar, Drive, Slack, Notion, GitHub, Linear, Outlook) and your history. For repeat emails that means you type the point once, and it drafts the rest, using what is on screen (the profile, the thread, the calendar) so the name and details are right.
Templates save typing and cost you personalisation. Mail merge costs you the reply. Opsis aims for the middle: each email is drafted for that person, and you read it before it goes. It doesn't send anything on its own.
How it compares.
Handling repeat email, as of November 2026
| Approach | Personalised | Effort per email | Risk |
|---|---|---|---|
| Opsis | Yes, drafted from notes and what's on screen. | A few words, then read and Tab. | A draft can miss a fact. You read it before sending. |
| Saved templates and snippets | Only where you edit. | Low, if you remember to edit. | Forgotten edits and stale details. |
| Mail merge | Name and fields only. | Low per email, high setup. | Reads as bulk. |
| ChatGPT in another tab | Yes, if you paste context. | High: switch, paste, prompt, copy. | Pasting other people's details into a chat. |

Who it's for.
Recruiters, sales development reps, customer success managers and executive assistants who send many similar messages a day.
Your data.
Opsis only follows the apps you share. Private windows and password managers are never recorded. When assistance is on, the text it needs is processed in the cloud with your consent, encrypted in transit and at rest, with zero data retention at our AI providers. Opsis isn't a screen recorder. You can pause, disconnect an app or delete your history whenever you like. Read the privacy policy · How Opsis handles data.
Where this works and where it doesn't
It works when the email is similar in shape and different in detail: interview scheduling, follow-ups, onboarding answers, client updates. It doesn't help with bulk sending or sequences. Use your sales tool for those.
