Start a pending transaction watch from your request
When you send a request to watch pending EVM transactions, have Notis start the supported mempool subscription and report the monitoring context.
Trigger
Email Sent
Triggers when a Gmail message is sent by the authenticated user. It polls the 'SENT' label and emits metadata including sender, recipients, subject, timestamp, and thread ID.
Action
Mempool Subscription
Tool to subscribe to real-time mempool updates for evm chains (ethereum, bnb, etc.). use after constructing your graphql subscription to stream pending transactions live.
Why this helps
Pending transaction monitoring can require a separate setup step that is easy to forget after writing the request.
- Start a live watch from a written request
- Keep the chain and monitoring purpose visible
- Reduce setup friction for time-sensitive observation
Setup
Build it in a few focused steps.
- 1Connect Gmail and Bitquery once in the Notis portal.
- 2Create an automation for EVM mempool monitoring requests.
- 3Tell Notis to process sent requests for pending transaction monitoring, construct a suitable EVM mempool subscription for the named network, and report subscription status and scope.
- 4Select Email Sent as the trigger.
- 5Choose a report channel and test with a real request for a supported EVM chain.
Questions about this workflow
Which chains are supported?
The mempool capability covers EVM chains such as Ethereum and BNB. Confirm the requested network is supported before subscribing.
Does this report confirmed transactions?
It monitors pending mempool updates. Use a separate query if you need confirmed transaction history.

Supported Triggers and Actions
Notis builds workflows that link Gmail to Bitquery. A trigger fires from one place; an action lands in another.
Gmail triggers
Bitquery actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Aliases Metric
Tool to use graphql aliases to rename fields in the response for clarity and disambiguation. use when you need to query multiple metrics with identical field names in one call.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Archive Database Query
Tool to query the archive database. use when you need full historical blockchain data (delayed by tens of minutes to hours).
Email Sent
Triggers when a Gmail message is sent by the authenticated user. It polls the 'SENT' label and emits metadata including sender, recipients, subject, timestamp, and thread ID.
Combined Database Query
Tool to query the combined database, which merges archive and real-time databases. use when you need both historical and up-to-the-second blockchain data in one request.
New Gmail Message Received Trigger
Triggers when a new message is received in Gmail.
Conditional Metrics Snippet
Tool to generate a graphql metric snippet with conditional logic. use when you need to apply filters directly on metric calculations via the `if` attribute.
Count Distinct Metric
Tool to use the count distinct metric to aggregate unique values for a field. use when you need to count the number of unique occurrences in a dataset.
Count Metric
Tool to use the count metric to aggregate the number of records matching a graphql query. use when you need simple record counts.
Database Selection
Tool to select the database (archive, realtime, combined) to query at the top level of a graphql request. use after determining whether you need live, historical, or combined blockchain data.
Early Access Program Query
Tool to access streaming data across various blockchain networks for evaluation purposes. use when querying chains not available via the v2 endpoint; limited to real-time data only.
