Never let important email attachments slip through
Clients send contracts, partners send proposals, and investors send documents. Notis creates Slack reminders when attachments arrive so nothing gets forgotten.
Trigger
New Gmail Message Received Trigger
Triggers when a new message is received in Gmail.
Action
Create a reminder
Creates a slack reminder with specified text and time; time accepts unix timestamps, seconds from now, or natural language (e.g., 'in 15 minutes', 'every thursday at 2pm').
Why this helps
Emails with important attachments get buried under other messages. Founders forget to download, review, or act on documents that were attached weeks ago.
- Ensure important attachments are processed on time without manual flagging
- Reduce the embarrassment of forgetting to review documents that were sent
- Automate attachment detection so you don't have to remember to check
- Create accountability around time-sensitive documents (contracts, proposals)
Setup
Build it in a few focused steps.
- 1Connect Gmail and Slack to Notis.
- 2Create an automation: ask Notis 'When I receive an email with an attachment, create a reminder to process it' or use the portal.
- 3Describe the outcome: 'Create a reminder with the sender, subject, and number of attachments. Set for one hour from when the email arrived.'
- 4Select the trigger: New Gmail Message Received that contains attachments.
- 5Choose a Slack channel for run reports.
- 6Test by emailing yourself a document and verifying a Slack reminder is created.
Questions about this workflow
Does this work for all attachments or only certain types?
You control it. Tell Notis in your prompt which file types matter (e.g., 'only PDFs and Word documents' or 'all files').
When should I be reminded?
Set your preference in the prompt (e.g., 'immediately' or 'at 4pm the next day'). You decide what works for your workflow.
Can I exclude certain senders?
Yes. Specify in your prompt which senders' attachments you want reminders for (e.g., 'only from clients and partners' or 'skip automated reports').
