Batch-check contact lists from Slack
When a channel message shares a list of addresses, let Notis send the list to Emailable for a batch check.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Verify Batch Emails
Tool to verify a batch of up to 50,000 email addresses. use when you need bulk deliverability checks for many emails at once.
Why this helps
Validating a long list one address at a time can turn a simple cleanup into a tedious task.
- Submit multiple addresses in one batch.
- Avoid repetitive single-address checks.
- Get a batch job started from the place the list was shared.
Setup
Build it in a few focused steps.
- 1Connect Slack and Emailable to Notis once through the portal.
- 2Create a new automation in the portal and name it for contact list checks.
- 3Write one plain-language prompt telling Notis to submit a clearly labeled email list from a Slack channel message for batch verification.
- 4Choose Channel Message Received, pick a channel for run reports, and test with a small real list.
Questions about this workflow
How many addresses can a batch contain?
The provided Emailable action supports a batch of up to 50,000 email addresses.
Will every address in every channel message be submitted?
Use the prompt to specify how a list should be identified, such as a message labeled for verification, so ordinary conversation is not treated as a list.
