A subscription request arrives from another system 2. Agent adds the sender with Manage List Subscription 3. Agent sets custom fields with Update Contact Properties 4. Agent sends the welcome with Send Email from a stored template 5. Agent reads Get Message History to confirm the send registered 6. Marketing channel gets a running count of new subscribers 7. A bulk send to a large audience routes for approval first ## What This Integration Enables An agent can send a transactional email through the Send API v3.1 with HTML content, attachments, and stored templates, or send up to 50 fully-formed messages in a single bulk call. It manages the Mailjet global contact database: create, read, list, update, and delete contacts, set custom property values, and add, remove, or unsubscribe a contact from a list in one call. Contact lists and templates are readable, so a flow can place a contact on the right list and render the right template. Around the send, the agent monitors deliverability. It lists processed messages, reads a single message's details and its event history (sent, opened, clicked, bounced), and pulls aggregated statistics scoped to the whole account, a campaign, or a list. Mailjet exposes no event triggers in this integration, so flows start from the systems feeding it: an inbox, a spreadsheet, or a scheduled sweep. The agent is the bridge between the systems that generate contacts and the mail that reaches them. ### Without FlowRunner **Contacts scattered**: Subscribers live in one system and the sender in another **Properties never set**: Contacts arrive with no country, plan, or name to segment on **Sends unverified**: No one checks whether a message was accepted after it went out ### With FlowRunner **One contact database**: Create Contact and Manage List Subscription keep the audience in sync **Properties set on entry**: Update Contact Properties fills the fields campaigns segment on **Sends confirmed**: Get Message History returns the event trail for a sent message ## Use Case Scenarios ### Subscribe and Welcome A [Gmail](https://flowrunner.ai/integrations/gmail-service) On New Email trigger fires with a subscription request. The agent calls Manage List Subscription to add the sender to a contact list, then Send Email to deliver a welcome message from a stored template. The subscriber is on the list and greeted in one run. ### Sync a Roster With Properties The agent reads a mailing roster from [Google Sheets](https://flowrunner.ai/integrations/google-sheets) with Get Rows, then calls Create Contact and Update Contact Properties for each row to sync subscribers into Mailjet with the fields campaigns segment on. The roster becomes a queryable, segmentable audience, not a static spreadsheet. ### Campaign Performance Report After a Send Bulk Emails run, a scheduled flow calls Get Stat Counters and logs the delivered, opened, and bounced counts to [Google Sheets](https://flowrunner.ai/integrations/google-sheets) Add Row. The marketing team gets a performance report without exporting anything by hand. ## Human-in-Loop Highlight A bulk send reaches up to 50 fully-formed messages in a single call, and a mistake in the template or the recipient set reaches all of them at once. When the agent is about to run Send Bulk Emails to an audience above the size you set, it treats the send as a [human-in-the-loop](https://flowrunner.ai/concepts/human-in-the-loop) step. It pauses, shows the template or subject, the recipient count, and a sample recipient, and routes approval to a marketing owner through Slack or email. The owner approves, and the agent sends the batch. The owner holds, and nothing goes out. Single transactional sends flow untouched; the batch that reaches an audience gets a human first. Agent processes routinely Detects exception requiring judgment Clear match Continues automatically Ambiguous Routes to human via Slack Human decides Agent resumes with decision ## Agent Capabilities 16 actions ### Sending 2 - **Send Email** Sends a transactional email through the Mailjet Send API v3.1.
