Outlook and Gmail can both store replies you send often, but each keeps them inside its own application. Here is where each feature is located, what it supports, and how to handle replies used in multiple applications.
Gmail: turn the feature on first
Gmail calls them Templates and ships them switched off. Settings (the gear) → See all settings → Advanced → enable Templates → Save Changes.
After that, write the reply in a compose window, then use the three dots at the bottom right → Templates → Save draft as template. To use one, open a compose window and pick it from the same menu. Gmail can also insert one automatically through a filter, which is the closest thing here to a real auto-responder.
Outlook: it depends which Outlook
- Classic Outlook — Insert tab → Quick Parts, or Insert → My Templates. Quick Parts keeps formatting, images and tables; typing a block’s name and pressing F3 inserts it without touching the menu.
- New Outlook — Insert tab → My Templates, and Quick Parts as well if your build has received them; Microsoft returned the feature during 2026 and it arrives by update. What did not come back with it matters if you are moving a library across.
- Outlook on the web — the same My Templates panel from the Insert menu of a message.
What each one cannot do
| Gmail Templates | Outlook My Templates | Outlook Quick Parts | |
|---|---|---|---|
| Works outside that mail app | No | No | No |
| Keeps images and tables | Yes | No — about 34 KB per template | Yes |
| Insert without leaving the keyboard | No | No | Classic Outlook only, with F3 |
| Fills in today’s date automatically | No | No | No |
| Moves with you to another tool | No | No | No |
The last row matters when you answer support tickets in a helpdesk, sales mail in Outlook and partner messages in Slack. Each built-in feature belongs to its application, leaving you to maintain three libraries with three different menus or keep a separate document for reusable text.
The same idea, one level down
Text Replacements stores the replies in Windows rather than in a mail client. You give each one a short trigger and it expands the moment you press Space, Enter or Tab — in Outlook, in Gmail in a browser, in Slack, in a helpdesk, in a form, in a document. There is no menu to open and no per-app library to maintain.
Two things it has that none of the built-in features do. For a date macro, put {date} or {time} in a snippet and it fills in the current one, so “I will get back to you by {date}” is correct each time it is used. It also imports and exports JSON or CSV, allowing you to move, back up and share a library instead of losing it when you change tools.
What it inserts is text. A template with a logo and a formatted table is a Quick Part, not a snippet, and for those Outlook is the right tool.
What to put in first
Useful starter snippets fall into these groups:
| Trigger | Expands to |
|---|---|
;ty | Thank you, I’ll get back to you shortly. |
;followup | Following up on my previous message… |
;meet | Would [time] work for a quick call? |
;decline | Thank you for reaching out, unfortunately… |
;ooo | I’m out of office until {date}… |
;sig | Your full sign-off block |
Start with the five you actually send daily rather than building a catalogue. A snippet you cannot remember the trigger for is slower than typing the sentence. A fuller set for support work covers what to add once the first five are automatic.
