the Send API (v3 and v3.1) for transactional and marketing email,\n  plus contact management, segmentation, campaigns, statistics, webhooks, the Parse API\n  and the Mailjet Templating Language.\n- **Content API** - programmatic management of email templates, template contents,\n  images, labels and authentication tokens (v1).\n- **SMTP Relay** - sending through Mailjet's SMTP servers, including custom headers.\n- **API Reference** - the complete, generated reference for every endpoint, built directly\n  from the OpenAPI specifications.\n\nBase URL for all REST APIs: `https://api.mailjet.com`.\nAuthentication uses HTTP Basic auth with an API key and secret key.\n\n## Machine-readable entry points\n\nPrefer these when you need the API surface in as few requests as possible:\n\n- `/openapi/openapi-mailjet.md` - the **complete** Email API reference (every endpoint,\n  grouped by resource) as a single Markdown document.\n- `/openapi/openapi-passport.md` - the **complete** Content API reference as a single\n  Markdown document.\n- `/_bundle/openapi/openapi-mailjet.yaml` - the raw, fully bundled OpenAPI 3 description\n  of the Email API.\n- `/_bundle/openapi/openapi-passport.yaml` - the raw, fully bundled OpenAPI 3 description\n  of the Content API.\n- `/sitemap.xml` - every indexable URL on this site.\n\nEvery page on this site is also available as clean Markdown by appending `.md` to its URL."},"sections":[{"title":"Email API","description":"Sending, contacts, campaigns, statistics, webhooks and templating.","includeFiles":["docs/email-api/**/*.md"],"excludeFiles":[]},{"title":"Content API","description":"Manage templates, template contents, images, labels and tokens.","includeFiles":["docs/content-api/**/*.md","docs/content-api.md"],"excludeFiles":[]},{"title":"SMTP Relay","description":"Send email through Mailjet's SMTP servers.","includeFiles":["docs/smtp-relay/**/*.md"],"excludeFiles":[]},{"title":"API Reference","description":"Complete generated reference for every Mailjet API endpoint.","includeFiles":["openapi/openapi-mailjet.yaml","openapi/openapi-passport.yaml","docs/api-reference/**/*.md"],"excludeFiles":[]},{"title":"Migrating from Mandrill","description":"Guides for switching from Mandrill to Mailjet.","includeFiles":["docs/mandrill/**/*.md"],"excludeFiles":[]}],"excludeFiles":[]},"priority":0.8},"dynamicMarkdocComponents":[],"compilationErrors":[],"ast":{"$$mdtype":"Tag","name":"article","attributes":{},"children":[{"$$mdtype":"Tag","name":"Heading","attributes":{"level":1,"id":"send-in-bulk","__idx":0},"children":["Send in bulk"]},{"$$mdtype":"Tag","name":"p","attributes":{},"children":["To send messages in bulk, package the multiple messages inside the ",{"$$mdtype":"Tag","name":"code","attributes":{},"children":["Messages"]}," property."]},{"$$mdtype":"Tag","name":"p","attributes":{},"children":["The messages’ order is preserved from the user input, allowing you to identify which message response corresponds to your original message payload."]},{"$$mdtype":"Tag","name":"Heading","attributes":{"level":3,"id":"example","__idx":1},"children":["Example"]},{"$$mdtype":"Tag","name":"Tabs","attributes":{"size":"medium"},"children":[{"$$mdtype":"Tag","name":"TabItemFragment","attributes":{"label":"cURL","disable":false},"children":[{"$$mdtype":"Tag","name":"CodeBlock","attributes":{"data-language":"shell","header":{"controls":{"copy":{}}},"source":"# This call sends 2 messages to 2 different recipients.\ncurl -s \\\n\t-X POST \\\n\t--user \"$MJ_APIKEY_PUBLIC:$MJ_APIKEY_PRIVATE\" \\\n\thttps://api.mailjet.com/v3.1/send \\\n\t-H 'Content-Type: application/json' \\\n\t-d '{\n\t\t\"Messages\":[\n\t\t\t\t{\n\t\t\t\t\t\t\"From\": {\n\t\t\t\t\t\t\t\t\"Email\": \"pilot@mailjet.com\",\n\t\t\t\t\t\t\t\t\"Name\": \"Mailjet Pilot\"\n\t\t\t\t\t\t},\n\t\t\t\t\t\t\"To\": [\n\t\t\t\t\t\t\t\t{\n\t\t\t\t\t\t\t\t\t\t\"Email\": \"passenger1@mailjet.com\",\n\t\t\t\t\t\t\t\t\t\t\"Name\": \"passenger 1\"\n\t\t\t\t\t\t\t\t}\n\t\t\t\t\t\t],\n\t\t\t\t\t\t\"Subject\": \"Your email flight plan!\",\n\t\t\t\t\t\t\"TextPart\": \"Dear passenger 1, welcome to Mailjet!
