Check for existing contacts before adding another
When a new contact is discussed, ask Notis to search for a matching Dialmycalls entry and report possible matches before you decide what to do.
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
List Contacts
Tool to list all contacts in your contact list. use when fetching paginated or filtered contact data for review (e.g., after adding or updating contacts).
Why this helps
Duplicate contacts create extra cleanup and make recipient lists harder to trust.
- Check for a likely existing entry before creating another.
- Use details stated in Slack to guide a contact search.
- Keep the final decision with the person requesting the check.
Setup
Build it in a few focused steps.
- 1Connect Slack and Dialmycalls to Notis once in the portal.
- 2Create an automation in the portal or ask Notis to check for an existing contact when requested in Slack.
- 3Write one plain-language instruction: search using the provided phone number or name and report possible matches without adding or editing contacts.
- 4Choose the channel-message trigger and reporting channel, then test with one real duplicate-check request.
