Every hour
Labeled emails as calendar events
Every hour, Leta adds a Google Calendar event for each labeled conversation in Gmail, read from its newest labeled email, then removes the label.
Gmail + Google Calendar integration
Combine Gmail + Google Calendar and move meetings into your inbox. Just ask Letaido's AI agent and watch it do the work.
Best Gmail and Google Calendar integration jobs to start with
Use this Gmail Google Calendar integration to turn emails into events and book meetings.
When you ask
Book the meeting agreed in an email
Leta books the meeting time you agreed by email, if it's still open, invites everyone with a Meet link and drafts the confirmation.
When you ask
Reply to a meeting request with open times
Ask Leta to answer a meeting request; it reads the email, finds three open times on your calendar and saves a reply draft offering them.
Every weekday at 7:30am
Meeting prep brief in your inbox
Each weekday morning, the agent reads your recent emails with today's outside guests and emails you one short prep brief.

Read the full comparison
| Option | What starts it | Good for | Keep in mind |
|---|---|---|---|
| Letaido AI agent | A schedule, or when you ask | Any email you label added as an event, meetings booked at the time agreed in a thread, reply drafts offering your open times, a morning prep brief from your email history | Neither app has an event trigger in Letaido, so a new email can't start a job; the label job checks every hour. Gmail needs your own Google Cloud OAuth client |
| Events from Gmail and Create event | Gmail spotting a booking email, or you, one email at a time | Flights, hotel and restaurant reservations and ticketed events added on their own; any other email turned into an event from the message's More menu, with its subject, text and recipients copied | Events from Gmail only covers confirmations, not emails you're cc'd on or sent to a mail list, and is off by default in the EEA, the UK, Switzerland and Japan. Create event works one email at a time |
| Gemini in Gmail | You, from an email or a draft | An Add to calendar button on emails that mention an event, and Help me schedule, which suggests times when you and your guests are available in your reply | Needs an eligible Google Workspace or Google AI plan. Add to calendar is English and web only and adds no other guests |
| Zapier | A Gmail trigger such as New Labeled Email or New Email Matching Search, or a Google Calendar event | Fixed recipes such as creating Google Calendar events from new Gmail emails. Replying with open times needs a multi-step workflow you configure, using Find Busy Periods in Calendar and Create Draft Reply | You build and maintain one workflow per job. Gmail triggers poll on an interval, and reading a date out of an email needs Quick Add Event or an extra AI step |
Gmail and Google Calendar: the old way vs. Letaido
- 1Open each email with a date in it
- 2Work out the time and time zone
- 3Create the event in Google Calendar
- 4Copy the details into the description
- 5Archive or relabel the email
Every hour, find the emails I've labeled 'To Calendar' in Gmail. For each labeled conversation, read the date, time and place its newest labeled email gives and add an event to my primary Google Calendar: a short title, the time in the time zone the email states, the location if there is one, and a description with the sender, the subject and a two line summary. If the email gives only a date, make it an all-day event that doesn't block my time. Don't invite anyone. Then remove the 'To Calendar' label from that conversation. If an email has no clear date, leave its label on and tell me.
Calendar, tab New events
Nov 12, Webinar: Email benchmarks 2026 (Larkspur Studio), 11:00am to 12:00pm ET
Nov 18, Brightline Marketing Summit, All day, doesn't block time
Both conversations no longer carry the To Calendar label. Still labeled: "Coffee soon?" from priya@bluefin.example, which gives no date.

Frequently asked
Does Gmail integrate with Google Calendar? +
Yes. Google adds flight, hotel, restaurant and ticket confirmations from Gmail to your calendar, and you can create an event from any email one at a time. Letaido adds jobs with judgement on top: Leta turns the emails you label into events, books meetings agreed by email and drafts the replies.
How do I connect Gmail and Google Calendar to Letaido? +
Connect Gmail with your own Google Cloud OAuth client, then connect Google Calendar on Google's consent screen. After that, describe the job in chat, or paste a prompt from a job on this page.
How do I automatically add events from Gmail to Google Calendar? +
Label the email To Calendar in Gmail. Every hour, Leta adds one event for each labeled conversation, reading the date, time and place from its newest labeled email, then takes the label off. It works for any email, not only bookings and tickets, and a conversation with no clear date keeps its label.
Can a new email in Gmail start a job? +
No. Neither Gmail nor Google Calendar sends events to Letaido, so a new email or a calendar change can't start a job. Jobs run on a schedule, such as every hour, or when you ask.
Does it send emails or invites for me? +
Replies and confirmations are saved as Gmail drafts for you to send, and the label job invites nobody. The prep brief is the one email Leta sends, and only to you. When you ask Leta to book a meeting agreed by email, the guests get the invite because the request asks for it.
How is Letaido different from Gemini in Gmail or Zapier? +
Gemini in Gmail adds an event or suggests times when you click, and needs an eligible Google Workspace or Google AI plan. With Zapier, you build and maintain one workflow per job, and replying with open times needs a multi-step workflow you configure. Leta reads both apps in one job and uses judgement, like reading a time zone from an email or checking you're still available before it books.
Will it ask before it changes Gmail or Google Calendar? +
Yes. Allow all read operations once per app; approve each kind of write once.
