Migreren van Mailjet

I am moving an email integration from Mailjet to Bird. Route through it with me.
1. Check what you already have before setting anything up. If Bird's MCP server is connected, use its tools. If the Bird CLI is installed and signed in, use that. Either one is enough, and every step below is an action you take with whichever you have. Only if neither is present, follow https://bird.com/docs/ai/set-up-your-agent.md to set one up and sign me in. Every Bird docs page serves Markdown at its own URL with `.md` appended, so fetch that rather than the HTML.
2. Read https://bird.com/docs/guides/email/migrate/mailjet.md for the payload, suppression and event mapping, and https://bird.com/docs/guides/email/migrate.md for the order the steps go in.
3. Find and list my Mailjet usage in this repository before you change anything: the POST /v3.1/send call sites and any SDK wrappers around them, the event handler and the URL it is registered at, and every domain I send from.
4. Register each of those sending domains with Bird and give me the DNS records to publish, following https://bird.com/docs/guides/email/sending-domains.md. Leave every DNS record my current provider uses exactly as it is: Bird's records are published alongside them and both providers authenticate side by side until I switch traffic. Publishing DNS affects mail for the whole domain, so show me the records and let me publish them.
5. Export my blocklist from Mailjet and import it into Bird before any production traffic goes through Bird, so my first sends do not reach addresses that already bounced or complained. Read it through the contact-management API, or from the contact statistics pages if that is what I have access to. The Bird import takes one address per request and is idempotent, so a partial re-run is safe. https://bird.com/docs/guides/email/suppressions.md has the reason taxonomy.
6. Port the send call and the event handler using the mapping tables on the provider page. Mailjet posts a Messages array of PascalCase objects, and each entry becomes either one flat Bird send or one entry in a batch, so tell me which shape my call sites map onto before you rewrite them. EventPayload becomes metadata. Bird signs deliveries per Standard Webhooks rather than Mailjet's scheme, so treat verification as a rewrite rather than a URL change: https://bird.com/docs/guides/webhooks.md and https://bird.com/docs/guides/email/events.md.
7. Run my whole integration against Bird's mail sandbox before any production traffic, following https://bird.com/docs/guides/email/testing-sandbox.md. Sandbox sends run the real pipeline without reaching an inbox or touching my sending reputation.
8. Stop and ask me wherever a step needs a decision. Do not point production traffic at Bird until I have seen the sandbox results and replied with the words cut over to Bird. Retiring the Mailjet path is a separate step that comes later: ask me again and wait for me to reply with the words retire the Mailjet path. A reply that agrees without naming what it is authorising is not authorisation. Finish by telling me what is left that only a person can do.
