Plus your region. The free call account { op: "connections.requirements", service: "mailjet" } lists exactly what to paste. **Can an AI agent delete or change things in Sinch Mailjet?** Only if its key allows it, and only with an explicit confirmation. 16 Sinch Mailjet actions are destructive, including delete Contact List, delete a contact (GDPR) and delete Template. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it. **Will an AI agent use up my Sinch Mailjet API limit?** actionlake paces every call to the limits in the Sinch Mailjet service file: 300 calls a minute per connection. Repeated reads are answered from cache (89 Sinch Mailjet actions can be), which never reaches Sinch Mailjet. **What does a Sinch Mailjet action cost?** One upstream call, the only unit actionlake bills. A list that pages bills one call per page (176 Sinch Mailjet actions page). Cache hits, searches, dry runs and calls Sinch Mailjet refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000. **Which Sinch Mailjet API does it cover?** The Mailjet Email API v3 / Send API v3.1 / Content API v1 (OpenAPI 3.1.0 bundles) at your region's mailjet.com address, set when you connect. It is built from Sinch Mailjet's documentation as read on 23 October 2026. 176 actions in 47 areas, each one in the signed service file (version 1.0.0). **Can I combine Sinch Mailjet with my other systems?** Yes. ask joins Sinch Mailjet to HaloPSA or NetSuite on the same customer and returns the answer rather than every row. Sinch Mailjet maps crm.contact, which 192 other connectors also map. **Does actionlake keep my Sinch Mailjet data, and where?** actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Sinch Mailjet credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models. **Which AI clients can use it?** Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names. ## More connectors like Sinch Mailjet Shares the most action names with - [Twilio SendGrid 48](https://actionlake.com/connectors/twilio-sendgrid) - [Resend 43](https://actionlake.com/connectors/resend) - [Elastic Email 42](https://actionlake.com/connectors/elastic-email) - [Bird 32](https://actionlake.com/connectors/bird) - [Dotdigital 26](https://actionlake.com/connectors/dotdigital) - [Mailtrap 23](https://actionlake.com/connectors/mailtrap) Joins with, on shared entities - [Brevo 3](https://actionlake.com/connectors/brevo) - [ActiveCampaign 2](https://actionlake.com/connectors/activecampaign) - [Nutshell CRM 2](https://actionlake.com/connectors/nutshell-crm) - [ZoomInfo 2](https://actionlake.com/connectors/zoominfo) - [SMTP2GO 2](https://actionlake.com/connectors/smtp2go) - [ConnectWise PSA 1](https://actionlake.com/connectors/connectwise-psa) Browse - [All Email & messaging connectors](https://actionlake.com/connectors/category/email-and-messaging) - [All connectors](https://actionlake.com/connectors) - [How actionlake compares](https://actionlake.com/compare) actionlake is independent.
