Turn External Submissions Into Email Records
Form submissions, API webhooks, and external triggers get lost in Slack. Notis creates an email draft so you have a permanent, searchable record in your email archive.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Create email draft
Creates a gmail email draft, supporting to/cc/bcc, subject, plain/html body (ensure `is html=true` for html), attachments, and threading.
Why this helps
Custom integrations and external forms fire data to Slack, but it gets buried and forgotten. You need a searchable record that persists beyond Slack's history limit.
- Create a permanent record of every external submission
- Keep data in your email archive for compliance and reference
- Reduce noise in Slack by routing forms to email instead
- Enable team members to find past submissions without scrolling
Setup
Build it in a few focused steps.
- 1Connect Gmail to Notis and get your webhook URL from the Notis portal.
- 2Configure your form or external system to send data to that URL (most form tools have webhook options).
- 3Create an automation: 'When this webhook receives data, create an email draft with the submission.'
- 4Map the key fields you want to capture (name, email, message, etc.).
- 5Test by submitting a form; you'll see a draft appear in Gmail.
Questions about this workflow
Can I send these as emails instead of drafts?
Yes. Notis can automatically send them to a team email or archive address. Great for lead capture workflows.
Does Notis handle multiple forms?
Yes. Each form gets its own webhook URL and automation, so you can route them to different Gmail labels or recipients.
What if a submission needs human review?
Keep it as a draft. Notis can also notify your team in Slack that a new submission arrived, balancing automation with visibility.
