1. Brevo
Best like-for-like: marketing plus transactional in one
What it does better than Mailjet
Brevo, like Mailjet, unifies marketing campaigns and transactional email via API and SMTP, but adds stronger automation, SMS, a built-in CRM, and unlimited contacts on send-based pricing. Its marketing feature set is considerably deeper. It's the most natural upgrade if you want to keep both jobs in one tool.
Where Mailjet still wins
Its transactional deliverability, while solid, isn't as specialized as a dedicated provider like Postmark.
Best for: Teams wanting marketing and transactional email unified with more features.
