Read the full comparison
| Option | What starts it | Best for | Watch out for |
|---|---|---|---|
| Letaido AI agent | A schedule, someone mentioning @Letaido in Slack, or when you ask | Jobs that need judgement: triaging a shared inbox with reply drafts, posting real lead emails to #sales, follow-ups for unanswered emails, emails drafted from a Slack thread or channel | Gmail has no event triggers in Letaido, so emails reach Slack on the job's schedule, not as they arrive. Gmail needs your own Google Cloud OAuth client. These jobs save drafts, they don't send |
| Slack for Gmail add-on | You, from the Slack icon in Gmail's side panel | Sharing one email with a channel or a teammate, with a note and its attachments | One email at a time, by hand. Up to 1 MB of headers and body, 30 MB with attachments, and 20 attachments. A Google Workspace admin may need to approve it |
| Slack channel email address | An email sent or forwarded to the channel's own address, for example by a Gmail filter | Posting every email that matches a filter into a channel or DM | Channel and DM addresses need a paid Slack plan; forwarding to your own Slackbot DM works on all plans. Each email is posted as it is, with no sorting or summary. Slack does not specify delivery timing |
| Slack Workflow Builder | A new Gmail message, or a form someone fills in Slack | Gmail templates such as posting a new Gmail message, or filling out a form in Slack to send a Gmail message | Only on paid Slack plans. Each workflow does one fixed thing. A new Gmail message can start it, but Slack doesn't say how quickly it posts |
| Zapier, Make and similar | A Gmail event such as a new email, a new labeled conversation or a new attachment | Fixed recipes such as sending new Gmail emails as Slack channel messages, DMs for new emails, or a daily email digest with AI steps | You build and fix one workflow per job. Zapier checks Gmail for new mail every 15 minutes on its lowest plan. Adding judgement means extra AI and digest steps |
Slack and Gmail: the old way vs. Letaido
- 1Open the shared inbox
- 2Read every new email
- 3Decide what needs a reply
- 4Copy the important ones into Slack
- 5Write each reply
Every weekday at 8am, go through the emails that reached our shared hello@ inbox in the last day, skipping promotions, social, updates and forums. Sort them into urgent, needs a reply and FYI. For each one that needs a reply, read the whole thread and save a reply draft in it. Then post the list to #inbox with sender, subject, one line on what they want and whether a draft is waiting. Don't send anything.

Frequently asked
Does Slack integrate with Gmail? +
Yes. Slack's own Slack for Gmail add-on shares one email at a time with a channel or teammate, and a channel email address posts every email you forward to it. Letaido's AI agent, Leta, adds jobs on top that need judgement, like triaging a shared inbox or posting only the real lead emails to #sales.
How do I connect Gmail to Slack with Letaido? +
Connect Slack and Gmail once in Letaido. Gmail connects with your own Google Cloud OAuth client. Invite the Letaido bot to each channel it should read or post in, then describe the job in chat, or paste a prompt from a job on this page.
Can a new Gmail email start a job? +
No. Gmail has no event triggers in Letaido, so emails reach Slack on the job's schedule, not as they arrive. A job can also start when someone mentions @Letaido in Slack, or when you ask. To post every matching email, forward it to a Slack channel email address.
Will Leta send the emails for me? +
No. The jobs on this page save drafts in Gmail, such as reply drafts, follow-ups and client updates. You read, edit and send each one yourself.
Is there a way to turn a Slack thread into an email draft? +
Yes. Tag @Letaido in the thread with an email address, and Leta reads the thread, saves a Gmail draft to that address with what was agreed and the next steps, and replies in the thread. Mention jobs need the app_mention event switched on in your Slack app.
Can Zapier send Gmail emails to Slack? +
Yes. Zapier runs a fixed recipe you build, like sending each new Gmail email as a Slack message, and you build and fix one workflow per job. Leta runs a job you describe and can sort emails, skip newsletters and pitches, and draft replies before it posts.
Do I have to approve what it posts in Slack or saves in Gmail? +
Allow all read operations once per app; approve each kind of write once.
