- Not legal or financial advice
- Cannot change outcomes for accurate items

Mailjet
Mailjet is a Sinch-owned email platform handling both marketing campaigns and transactional sending from one account. It offers a collaborative drag-and-drop editor, an email API with SMTP relay, AI generation and segmentation, and EU-based data centres.
- One sending reputation to manage instead of two across separate vendors
- Real-time co-editing removes the export-and-reimport handoff that slows email production
- EU data centres and ISO 27001 clear European procurement that US-hosted rivals stall at
- Certified Sender Alliance participation is a concrete deliverability advantage in DACH
- Competent at both marketing and transactional rather than exceptional at either
- Sibling product Mailgun may fit better if you only send transactional email
