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":[]}},"dynamicMarkdocComponents":[],"compilationErrors":[],"ast":{"$$mdtype":"Tag","name":"article","attributes":{},"children":[{"$$mdtype":"Tag","name":"Heading","attributes":{"level":1,"id":"spf-and-dkim-validation","__idx":0},"children":["SPF and DKIM validation"]},{"$$mdtype":"Tag","name":"p","attributes":{},"children":["SPF & DKIM are authentication systems that tell Internet Service Providers (ISPs), like Gmail and Yahoo, that incoming mail has been sent from an authorized system, and that it is not spam or email spoofing.
